I owned a 1969 Camaro (1981-1982) with a 350ci motor, I was 18yrs old at the time. I wish I still had that car today. I spun a bearing in the crank, sold the car for $1500 and threw in a set of 194 double hump Fuelie heads. The motor in the video is truly exceptional.
I had that same block.. 327 two bolt. Built it back balanced with very good internals and dart heads. 15 to 1 compression 650 horsepower 584 ft lb of torque. Use it in a mud truck, beanfield truck, and then a drag car. Very good block
Well if it is the L48 it's decent starting point. That the 350 295hp in '70 it was rated as 300hp but no changes were made. Decent engine back in 69 they were just quick as the 302 in the Z/28 and way more torque.
Frickin love this show. Over the years they have built so many cool engines and I love how Mike takes over the dyno and the boss man Pat makes sure nothing goes wrong. You guys kick A$$!
I've seen him wearing a t-shirt with a logo of his loaded pocket protector. Of course he uses all that stuff frequently so I don't give him any crap about it. I used to work in a parts store so I had a flashlight, plyers, screwdrivers and a knife on my belt. Everything I needed right there and no wasted time looking for it. That made the customers happy.
Can't wait for the day when I finally have time to rebuild my SBC. Guessing it will take me 30 minutes since it only takes the pros 10 minutes to rebuild one. ;)
WOW!!!!! The Trick Flow heads and intake work totally awesome!!!!! That is a great daily driver build. Great video and education!!!! I learned so much. Keep up the awesome work!!!
I don’t know why, but I like all the crossover #POWERNATION is doing with these folks. It just feels right. Thanks, y’all, for all the effort. It really is appreciated.
Would have picked up more across the board with a 64cc chambered head. Compression would have been at 10.2 to 1 and would have complimented the cam better. Nice build none the less.
@@KingJT80 That's right. It's been known for quite some time now - like 90 years or so, that all the big gains from comp come before ~ 9:1. After 9:1 the gains are still there of course but not as dramatic as they are before 9:1, in part because pumping losses from squeezing the extra comp start making the returns less. So moral of the story is 9 - 9.5:1 and go for it everywhere else and it will still make really good power. Big cam and plain ole 9:1 comp still yields big gains so long as the heads are good. With aluminum heads I'd 'risk' 10:1 though LOL (despite everything I've just said)
Nah the double heads weren't all that great for flame propagation and don't flow very good by modern standard. Plus advantages on timing alone on pump gas would make up for the bump in compression. The '71 76cc heads make more power than the older with the small or big valves, just a better chamber design. Plus the weight savings with aftermarket aluminum will help with acceleration and handling, the iron heads ~50lbs each, aluminum just over 20lbs each.
You can use those cracked blocks all day long if they where properly filled. They will run cool 😎 on the street the same way. The heat in the motor comes from the heads. If you put any power adders on those old blocks without filling them you will end up cracking the block anyways. Great 👍🏻 video to try to up sell all those different components though !!
Blocks already set up for a roller cam except they use retrofit roller lifters that are like three times the price They could have just used the stock ones with the spider and save the ton
@@BuzzLOLOL did you not see the build sheet. That’s the left over block from the 383 build. It was already .030 they went .030 more to .060 over. Which is says on the build sheet
@@BuzzLOLOL 🤣🤣🤣. I’ve bored 350 .080 over idk were the hell you heard that. I have a .060 350 in my truck been in it 10+ years. It never sees a day we’re the throttle isn’t buried. It runs 180 degrees all day long!!!!
One thing that should be done that's rarely is which is when someone plunks a good engine out for storage is pop the covers and loosen all the rockers.it seals the cylinders up and it doesn't ruin the valve springs that sit compressed. At the very least rotate the engine now n then. In the early 2000s I bought a Harley sportster engine that was completely rebuilt in 1982 (still had the tag hanging on the carb) then tossed on a shelf never run. Somehow the bores were immaculate not even flash rust but it had so much valve float it wouldn't tach much over 4500rpm. Yeah it's inconvenient to adjust the valves before running but was less work than replacing the springs. On a solid lifter Harley it only takes 10 minutes to adjust the pushrods.
@Douglas White You aren't lying. I was up last night looking up prices for a used Corvette. Black 2003, about 25k miles, for $26k. It's at a small place here in town, wondering if I can get it down to like $24k... IM ALREADY OBSESSED!
Excellent vid on a classic I'm a 283' and 327' kid back in the day never run the 350 much but them numbers I tried to achieve similar goals like this but on a all iron heads
My dad use to have a 355 in his 73 nova with the big valve camel hump heads eldebrock rpm intake flat top pistons thing it was like 11 to 1 compression 410 gears and had like a 540 solid cam with a good bit of duration it ran like 12 50
Love this build. As I am many months behind the time when these shows air and I get to see them, I am anxiously awaiting to see what Huff & Buff at Detroit Muscle install this beauty into.
FYI The Sniper handheld shouldn't flash off when you crank the engine. If it does, the 12V pink wire is going below double digit voltage when you're on the starter.
I've never er understood the "street engines usually don't go above half throttle" am I the only one who drives like I'm running from the boys in blue stop light to stop light?
That’s a very nice number, but i feel like it might be a lazy dog off the line with that big cam, how much vacuum at idle can this cam with 248@50 make in a 350 small block, unless they throw a deep gear in that bag and a big stall, not streetable anymore 😬
I love the show! But it is interesting that they used that large of a cam. HR292XE it sound like. I run one size smaller then that on my Afr headed 355 and it’s a bit much for a cruiser. That cam would probably need 3,200-3,500 stall to be happy.
442 HP and 442 Ibs of Torque out of a 350. Heck the 2011-2014 Charger Challenger SRT 392 Hemi as well as the 392 Hemi V8 in the Jeep Wrangler Rubicon 392 made 470 HP and 470 Ibs of Torque.
Sort of strange, somebody had rebuilt that engine at least once. 0.040 over bore in cylinder with pistons in pretty decent shape, but those clogged water passages in the head Im surprised the engine didnt overheat more often. If anybody is interested in that particular camshaft Im pretty sure it's the Xtreme Energy XR294HR
Sure is sad to see that block cracked. Numbers are the ones GM made the 302s out of in 1969. Not all of those blocks were 302 blocks, but that was the casting number for them. Have to look at the stamp pad on the front, to see. If it was stamped DZ, it was a 302, If not, it was a 350. That's not the OEM block for that car, and neither were the exhaust and heads, but they were good factory upgrades for it, probably at the time they were put in.
I will admit I'm impressed of the numbers it put out in the end. Being 91compression In dual plane intake. Very impressive guys I wish I could be in your shoes I would love to do that stuff all day long
13:04 You should offset your dogbone 90 degrees. Running it straight off like that increases the length of your tq wrench increasing the tq. Unless you did the math to compensate, then nevermind..
14:00 Wonder if I can buy that 10.1 oz tube of Permatex Right Stuff 1 Minute Gasket Maker around here? 3 oz. is about the same price! I usually use DAP Silicone Rubber in black but that is getting impossible to find... especially at a reasonable price... paid $2.99/10 oz. last time...
It would be interesting to have a segment explaining the machine tools. I know how to use a mill and lathe from shop in high school but I would love an explanation of the cylinder hone. Not everyone knows how to use those machines.
Would love to see how much low end torque you can pull out of a 350 chevy for a tow truck like my old 91 Suburban. High hp is fun and all for a nice Camaro but ya''ll have built some pretty torquey I-6s lately and I would love to see what you could do with a 350.
It's a 350 with similar spec's it's going to make much more torque than any gasoline inline 6, only 400 made more torque without going to a BBC. It's got 3.48" stroke and stock they were rated for 380lb-ft in 69'. My point is the 350 is great SBC truck engine. On the other hand a small turbo on the inline could make you a ton of torque with that inline 6 as it likely already has low compression wouldn't be hard or costly to do.
With a 268H roller cam and rocke3s .....10 to 1 comp with alumimum heads should be no issue with 93 octane. So much left om the table..but I get what he did Now get an Overdrive trans , rack n pinon , and 3.90 true track in that old Maro'
I would like to see you guys build the same 350 that came in the 1970 Z28 RS Camaro with the 350 double hump heads, I know that engine was alot more powerful than Chevy claimed it was, I think it was in the 400to450 hp range and same amount of torque if not more.
Love all of these videos, I've learned so much from watching. Question about the locked out distributor (15:25)... I was always under the impression locking out the distributor was more for race engines that would be operating primarily in their peak power band. Wondering if someone could explain (or direct me to another video) why a vacuum advanced MSD distributor wasn't the choice for this street engine? It just seems like this particular vehicle will be a cruiser and won't be seeing any racing, even if they did want some more pep under the hood.
love your video! I am hoping to get your opinion on something. I have a chevy 350 that I want to freshen up without machining. I specifically want to replace the main and rod bearings to increase engine longevity. So regarding the rod bearings, can I just replace them, do the clearance checks, and retorque them without having to change the rod bolts/nuts? Its just a stock, average HP late 70' engine that is just a daily driver. Thoughts on this?
They misspelled replaced!! That's not a rebuild kids!! Edit: Should have got an LS. Or put the original back together and that would have been fine for what is was.
Yes sir love your show question have 79camz28 have been sitting in garage 4yrs took it out put new gas in it crank and runs smooth but notice after let run To operating temp on pasenger side thé valve cover his is vert botter than thé drivers side does that have any thing To do with valves 350egine thé oilpressure is 60 at start up and at idle its good
Here's how to beef up your 350! Throw the block, rotating assembly, oil pan, oil pump, timing cover, heads, intake and valve train away, and get free stuff from your sponsors. So simple and easy to install!
The power was down for such a large cam and decent heads 🤔 Was it the type of Dyno they used or the 9:1CR on the aluminum heads? I've seen as much power from 224 degree cam with 9:.5:1 CR vortrec heads and a daul plane. Mabe the intake? I think it's the compression ratio and intake that are inadequate for the combination.
Was thinking the same thing, the large cam at 240’s .050 bleeds off a lot of compression so they in reality I wouldnt think they would even need 93 octane this baby would be safe to run on 87 as long as timing and load are in good ranges which they should be since they are going in a car not a truck, on the opposite side a 224 cam would be more in favor of keeping the dynamic compression relatively close to the static of 9.5:1 and give you better hp because of earlier intake valve closing event to pump that torque number
@@Matt44magnum44 yes with that size cam (bleeds off cylinder pressure) and aluminum heads (dissipates heat faster than iron);they should be able to go up to about 11:1 and run on 93 as long as the timing and fuel curve are dialed in like you said. And don't forget the converter.
@@famousinfamous2951 so now I have a question I’m building a engine with 10.5:1 compression with the cam I’m picking 230/236@.050 with 113 LSA it’ll bleed it down to 9.3:1, the block and heads need machining anyway so do you think if I get the heads shaved down to accept a static compression in the neighborhood of 12:1 only for the cam to bleed it down to high 10:1 to 11 more so high 10 with a .040 quench, aluminum heads, 2800 stall converter, 3.73 gears, piston oil squirters (which some say make a difference) and a car that weighs 3300 pounds, do you think it’ll live on 93 octane and a total timing of 36* it’s a sbc 355 btw
@@Matt44magnum44 is it EFI ? The wide lobe separation is good and chamber design? I haven't had much experience past 11:1 nominal but I would take thermostat temperature into account exhaust scavenging crankcase evacuation method and probably a little more Cam depending on how you use the vehicle. These are all the things I would consider and I would test. If I am wrong then I can only learn something.
@@famousinfamous2951 yes it’s a Holley sniper for the efi, 72cc heart shape chamber, I have a electric water pump with electric fans that will maintain 180* water temp, crankcase ventilation will be through valve covers into a nice puke can setup, exhaust scavenging will be through a x pipe, really it’s just a street motor, I’ve been speced by erson for a 226/234 with .577 .577 lift and by Mike Jones for 228/228 with .578 and .578 lift, I have dart pro 1 180cc intake runner and 75cc exhaust runner, was just looking at the comp xfi280 with the 230/236 I was talking about of course I like the 113 LSA better because of the flatter torque it would produce for street and since I have efi anyway, I would have to get it custom tho since I have a ‘75 non roller sbc.. sucks. But was really wanting more opinions on the matter before I pull the trigger on a $400 camshaft from a company lol
Ive always heard that you can what I call it here is advance the timing ahead a few notches and it would make it run alot better if you do it here and he just proved that you can do it too cool thanks for the info too now
What was the compression might have missed it? Just curious we have 350 with 11.6:1, trick flow 175s, and LT1 solid lift cam. We thought it might be around 450hp?
New block, crank, rods, pistons, heads, intake, cam... This is NOT a rebuild of a tired engine, this IS a new engine. 😆😂🤣
Well when you get your parts for free they can call it what they want. lolol

Could've followed their own advice and took a couple hours to port and match the intake for some free power

I would like to see you guys build the same 350 that came in the 1970 Z28 RS Camaro with the 350 double hump heads, I know that engine was alot more powerful than Chevy claimed it was, I think it was in the 400to450 hp range and same amount of torque if not more.
Love all of these videos, I've learned so much from watching. Question about the locked out distributor (15:25)... I was always under the impression locking out the distributor was more for race engines that would be operating primarily in their peak power band. Wondering if someone could explain (or direct me to another video) why a vacuum advanced MSD distributor wasn't the choice for this street engine? It just seems like this particular vehicle will be a cruiser and won't be seeing any racing, even if they did want some more pep under the hood.
love your video! I am hoping to get your opinion on something. I have a chevy 350 that I want to freshen up without machining. I specifically want to replace the main and rod bearings to increase engine longevity. So regarding the rod bearings, can I just replace them, do the clearance checks, and retorque them without having to change the rod bolts/nuts? Its just a stock, average HP late 70' engine that is just a daily driver. Thoughts on this?
great engine build fantastic street everyday driver and toasting most others !
This show is Great... I’ve learned so much!!!
442 and 442 SWEET!
Was expecting 500+ HP with that big cam... 9:1 compression ratio? Might only do 8 - 9 MPG...
They misspelled replaced!!
That's not a rebuild kids!!
Edit: Should have got an LS. Or put the original back together and that would have been fine for what is was.
Are the valve covers stock Chevy valve covers? I'm looking for a good set of roller rocket that will fit under my stock Chevy aluminum valve covers.
Good program, tanks for your pasion for engines best regards from guatemala.
I love to have this engine for my el camino project
When you degree a cam why not clock the cam sprocket to 0*? With the little half moon inserts that clock the sprocket? Do you know what I am saying?
Those are sweet numbers. That's a nice engine.
Yes sir love your show question have 79camz28 have been sitting in garage 4yrs took it out put new gas in it crank and runs smooth but notice after let run To operating temp on pasenger side thé valve cover his is vert botter than thé drivers side does that have any thing To do with valves 350egine thé oilpressure is 60 at start up and at idle its good
Here's how to beef up your 350! Throw the block, rotating assembly, oil pan, oil pump, timing cover, heads, intake and valve train away, and get free stuff from your sponsors. So simple and easy to install!
The power was down for such a large cam and decent heads 🤔 Was it the type of Dyno they used or the 9:1CR on the aluminum heads? I've seen as much power from 224 degree cam with 9:.5:1 CR vortrec heads and a daul plane. Mabe the intake? I think it's the compression ratio and intake that are inadequate for the combination.
Was thinking the same thing, the large cam at 240’s .050 bleeds off a lot of compression so they in reality I wouldnt think they would even need 93 octane this baby would be safe to run on 87 as long as timing and load are in good ranges which they should be since they are going in a car not a truck, on the opposite side a 224 cam would be more in favor of keeping the dynamic compression relatively close to the static of 9.5:1 and give you better hp because of earlier intake valve closing event to pump that torque number
@@Matt44magnum44 yes with that size cam (bleeds off cylinder pressure) and aluminum heads (dissipates heat faster than iron);they should be able to go up to about 11:1 and run on 93 as long as the timing and fuel curve are dialed in like you said. And don't forget the converter.
@@famousinfamous2951 so now I have a question I’m building a engine with 10.5:1 compression with the cam I’m picking 230/236@.050 with 113 LSA it’ll bleed it down to 9.3:1, the block and heads need machining anyway so do you think if I get the heads shaved down to accept a static compression in the neighborhood of 12:1 only for the cam to bleed it down to high 10:1 to 11 more so high 10 with a .040 quench, aluminum heads, 2800 stall converter, 3.73 gears, piston oil squirters (which some say make a difference) and a car that weighs 3300 pounds, do you think it’ll live on 93 octane and a total timing of 36* it’s a sbc 355 btw
@@Matt44magnum44 is it EFI ? The wide lobe separation is good and chamber design? I haven't had much experience past 11:1 nominal but I would take thermostat temperature into account exhaust scavenging crankcase evacuation method and probably a little more Cam depending on how you use the vehicle. These are all the things I would consider and I would test. If I am wrong then I can only learn something.
@@famousinfamous2951 yes it’s a Holley sniper for the efi, 72cc heart shape chamber, I have a electric water pump with electric fans that will maintain 180* water temp, crankcase ventilation will be through valve covers into a nice puke can setup, exhaust scavenging will be through a x pipe, really it’s just a street motor, I’ve been speced by erson for a 226/234 with .577 .577 lift and by Mike Jones for 228/228 with .578 and .578 lift, I have dart pro 1 180cc intake runner and 75cc exhaust runner, was just looking at the comp xfi280 with the 230/236 I was talking about of course I like the 113 LSA better because of the flatter torque it would produce for street and since I have efi anyway, I would have to get it custom tho since I have a ‘75 non roller sbc.. sucks. But was really wanting more opinions on the matter before I pull the trigger on a $400 camshaft from a company lol
I am confused by the ram's horn exhaust manifolds on a 1969 engine. If I remember right, 1967 was the last year for the ram's horn manifold.
Yall did a naturally aspirated build thTs alll
Snapon should make a tool box for that guys pocket 🤪
That's pretty badass. A Camaro would seriously haul with that under the hood.
the factory 10:1 CR 350 in 1969 was 300 gross hp, and the average ZZ crate 350 is 355 hp, so they had a real hurdle to cross there :)
I absolutely love this channel. I never get tired of their videos. You just can't beat American V8s.
That is going to be a powerful and sweet ride. a camaro with 442 horses. have mercy. !!
Would this build work on a 70’ LT1 350/370 from a corvette?
Tanks for much😉👍 nice rebuilding
I would like to see a little more on the 5.3 rebuild on an 08 pickup truck Silverado.
I love this show from phillipines
Hey salute from N.Y. U.S.A... I LOVE that you guys love guns out there.
@@CallofDoobie585 having a gun in the Philippines is like having a Lambo in the US. It's a status thing lol.
You still have cars over there?
442 horseporks from all natural 350 is pretty damn nice. I'd take that any day.
350s can make that all day long of course people say they can’t
“Just a little more peppy, something reliable, little choppy” throws a new crank, and forged pistons in it.
Question. Is gear drive timing better then timing chain . I know more noise.
I enjoyed the HELL outta this. Well done. Now more ; )
Ive always heard that you can what I call it here is advance the timing ahead a few notches and it would make it run alot better if you do it here and he just proved that you can do it too cool thanks for the info too now
I have one of these engines. It is great to learn about it.
Mikes physical change is crazy
Is necessary measure cranck clarance or not?
Keep the LS. I will stick with the traditional small block with a carburetor. No computer, no worries.
What was the compression might have missed it? Just curious we have 350 with 11.6:1, trick flow 175s, and LT1 solid lift cam. We thought it might be around 450hp?
"works most excellent", rock on dudes, wyld stallions would be proud
