Clean engine bay! Nice car. I see the old NHRA G/SA in the back window. My brother ran that combination for years. He sold his 68 Chevelle in favor of a 2011 Camaro. Cool video.
My first car in 71 was a 69 396 Chevelle. I was in 10th grade. Muncie trans. 4:88.1. gears. It ran superb. I know how you feel in a quick big block chevelle!! Can't wait for your next vid!!!
Had a 68 SS 396 (fake) magazine car early 90s Even with the wrong gear (super tall) that cammed up '96 would pull hard in every gear...never needed 5th . I was impressed...its just like a bigger 383 sbc but that bore really lets it breathe
It is great to see the results of a known HP and weight combination.The Moroso slide rule says the e.t. is right on but MPH is several MPH slow. Easily explained by it being a fairly large car. If it was in a 88 Firebird of the same weight it would run 130 all things being equal. At those speeds aero becomes an issue.Good job!!!
Do you think its got 130mph traps in it? Acceleration rate seemed to of tapered off on the big end. Maybe get a wideband O2 sensor? Thanks for all the great content.
Nice runs! That thing rips for the horrendous 5000 DA. I'm spoiled with 0 to 2600 DA on a bad day. The car leaves very well and I'm impressed with the 60ft. for leaving close to idle.
Car is well set up as is any decent stock eliminator build. The short times are very good for a mid 10 second ride, and the ET beats the MPH (1320/MPH=ET) Gearing well matched to the combo as well.
I really enjoy all of the videos that you have posted ! You mentioned that the Chevrolet has a turbo 350 transmission. I was hoping that you might give a little more info on the t-350. That's a lot of motor for a turbo 350 to handle as well as it does ! It must have some very robust parts in it ?
Exactly... wanna lose one of these new mush mouth "no-prep street racers" just try to explain how bracket racing works. They think there's only two ways to lose a race. I think the math is too hard for 'em.

Mark what was the lift and duration of that cam in your 1969 Chevelle? Did you have Large Port Rectangular Heads on it? Were the head ported and CC'd?

My slicks were 13x31's also.

Err... NO. TH350 has 2.52 1st, 1.52 2nd and 1.00 3rd. Assuming he shifts at 7000 RPM, engine RPM drops to 4222 RPM in 2nd and 4605 RPM in 3rd. From the dyno sheet in the previous video, the engine makes peak torque at 4200 RPM, and is thus perfect for his gear spreads.

Hey Mark what are the cam specs on the 496 ? I have a 427 60 over with afr 265 oval port heads it's around 10.3 to 1 compression my cam is a Howard's 235x241@50 with 618 lift on a 108 lsa. it's a hydraulic roller the motor made best dyno was 661 hp and 605 torque with a holly 950 and 32 degrees of timing I think the combo is pretty good but I'm thinking about a Lil more camshaft more duration would be a little better what's your thoughts?

Look up vortecpro on Google lots of builds and information excellent reputation. But he does have people that troll the shit out of him saying what he does is impossible and it's all bullshit. The man is very solid if I didn't build my own I would buy from him.
Wow if you had a gear swap change in the transmission don't know if you have it or not, developed for big block chevy drag and circle track by TCI the gear set spread is crucial and works just as well with small blocks in 3 speed automatic transmissions forgive me, i am not aware if you have a powerglide , th350 , th400, or manual transmission. The gearset i had in mind for you evens out the spread like a close ratio transmission and works with big block cars really well the automatic 3 speeds and also increases their load holding capability / durability. its if i remember correctly like a 2.20, 1.40, 1. to 1 ratios for tH350, then tailor your rear gear for launch or traps as usual. It cut a couple tenths at least and just over all maximizes everything and 60' the kit changes the first two gear ratios in TH400 and TH350's to even out the spread and allows more higher average high tq/hp numbers/ powerband laydown. Well don't know what ratios you have it looks great just something really i want to do in this 1981 camaro with a TH350, going with the 2.20 first , 1.40 second, 1:1 third gear set from another manufacturer i think PA has them now, TCI catalog stopped listing them. oh well just throwin somethin out there Your time and speed are awesome Great CHEVELLE.
Yea.... i see it now that you mention it, it has no belt going around the crank.. i guess it doesnt need an alternator because A he trailered it there an B with a deep cycle battery and a trickle charger betwen rounds theres no need for an alternator .. likely something to put on at the track and change out if/when youre streeting the car.
At about 6 minutes in, the undercarriage shot... your engine is bouncing front to rear quite a bit and separate from the chassis. I'd look at your transmission mount and see if you could tighten that up, and possibly the engine mount material. But watch your headers compared to the frame rails, that engine is moving a lot, and that direction isn't from torque.
I think a lot of that is the anti-shake algorithm of the video. If you watch, the shape of the rear end cover is all distorting in impossible ways due to the effect of the smoothing process for instance.
Dustin Meier i believe this is from not having roll cage bars from the upper firewall to the front of the frame horns. My Monte Carlo is fully caged except the front bars. The entire front clip flexes up from the last body mounts on the bottom of the firewall. Since the firewall is the hinge point, when the frame and engine go up in the front the header collectors drop twice as much in the back due to the length from the hinge point. You can tell when the car lifts and the front clip and engine droop the collectors get closer to the floor boards. Car slams down and collectors drop.
Want one of these so bad!! If I thought I could sell my current engine for enough I would. Mark is the only guy Id let build me a "crate" engine since my machinist passed away To build, assemble tune dyno or even test in his car..nobody does that. That idle at hot temps tells me he can tune these within a hair of perfection. Id be afriad that engine would rip my new GM T56 with all the hardened goodies to shreds Or 4,11 would be too steep? Mark would these hold up to most driving provided Im not an idiot with the car?
I'm not getting it ? You went ahead and stroked it to 496 but then went ahead with Iron head's ? With good flowing quality aluminum head's available today at incredible prices I'm not understanding the economy in the iron head choice never mind the huge weight saving's on the front end of the car ? Can you please enlighten Me ?
Dont really want to answer for the man but it can only be 1 of 2 reasons and maybe both. Hes an old school loyalist to the extreme and/or its one of many tricks that allows him to lower the cost of his engines for a wider client base. Got my attention because Im damn sure tired of how expensive stuff has gotten. Hes right at the power limit for stock connecting rods and the whole 9 so its a hell of a package for someone with a low budget, looking for something around that power range and that doesnt mind the extra 50lbs of the iron heads. Maybe someone that wants to paint the heads anyway for a stock look. Hes putting 600 lift cam in these motors but even then the head work to flow at that rate is impressive. I personally have lowered my power expectations to something my pocket book can afford and will be going in this direction. Going to just build something I can enjoy.
I have a "rowdy" race gas 496 with iron heads that makes around 720hp at 7400rpm. Runs 9.80s in the 1/4 in a G-body. I'm using ported rectangle port heads and a 775/748lift 288/296@.050 solid roller. 13.5-1 compression, DART singleplane with 1150 Dominator.
Good call, STILLtehPILLAR. He's got a G/SA decal on his window and that's NHRA Stock class. Have to run OEM heads with the casting number and correct year on the head. I'm guessing factory GM 1968 aluminum heads would blow the budget for this build.
I'd dial a 6.62 1/8 on the first pass and then go down to a 61 or a 60 as the evening went on and hope I didn't sleep on the tree. That car could make some money.
I love that its a simple set up in a factory stock body car with a roll bar its not tubed or narrowed something the average guy can build and go out and run mid 10s consistently without alot of maintenance and braking every other week great job.

4.56
Stock 12 bolt
What are them alternators you run on this thing..?
It’s an electric motor driving a belt around the stock water pump and fan. Less drag on the engine is the idea.
Yea.... i see it now that you mention it, it has no belt going around the crank..
i guess it doesnt need an alternator because A he trailered it there an B with a deep cycle battery and a trickle charger betwen rounds theres no need for an alternator .. likely something to put on at the track and change out if/when youre streeting the car.
At about 6 minutes in, the undercarriage shot... your engine is bouncing front to rear quite a bit and separate from the chassis. I'd look at your transmission mount and see if you could tighten that up, and possibly the engine mount material.
But watch your headers compared to the frame rails, that engine is moving a lot, and that direction isn't from torque.
Correction. 5:44
Dustin Meier at 3:37 you can see it too!
I think a lot of that is the anti-shake algorithm of the video. If you watch, the shape of the rear end cover is all distorting in impossible ways due to the effect of the smoothing process for instance.
Dustin Meier i believe this is from not having roll cage bars from the upper firewall to the front of the frame horns. My Monte Carlo is fully caged except the front bars. The entire front clip flexes up from the last body mounts on the bottom of the firewall. Since the firewall is the hinge point, when the frame and engine go up in the front the header collectors drop twice as much in the back due to the length from the hinge point. You can tell when the car lifts and the front clip and engine droop the collectors get closer to the floor boards. Car slams down and collectors drop.
@port nut not sure what you mean.
Want one of these so bad!! If I thought I could sell my current engine for enough I would.
Mark is the only guy Id let build me a "crate" engine since my machinist passed away
To build, assemble tune dyno or even test in his car..nobody does that.
That idle at hot temps tells me he can tune these within a hair of perfection.
Id be afriad that engine would rip my new GM T56 with all the hardened goodies to shreds
Or 4,11 would be too steep? Mark would these hold up to most driving provided Im not an idiot with the car?
good ET for the MPH..at 520 RWHP (650 FWHP), should be closer to 126...hot that day ...5200Ft. altitude : /
I'm not getting it ? You went ahead and stroked it to 496 but then went ahead with Iron head's ? With good flowing quality aluminum head's available today at incredible prices I'm not understanding the economy in the iron head choice never mind the huge weight saving's on the front end of the car ? Can you please enlighten Me ?
Dont really want to answer for the man but it can only be 1 of 2 reasons and maybe both. Hes an old school loyalist to the extreme and/or its one of many tricks that allows him to lower the cost of his engines for a wider client base.
Got my attention because Im damn sure tired of how expensive stuff has gotten. Hes right at the power limit for stock connecting rods and the whole 9 so its a hell of a package for someone with a low budget, looking for something around that power range and that doesnt mind the extra 50lbs of the iron heads. Maybe someone that wants to paint the heads anyway for a stock look. Hes putting 600 lift cam in these motors but even then the head work to flow at that rate is impressive. I personally have lowered my power expectations to something my pocket book can afford and will be going in this direction. Going to just build something I can enjoy.
Also, there may be a race class that requires iron heads. I don't know if there are any but could be.
Obviously the old shit can still get the job done. That's a "mild" 650 horsepower pump gas engine.
I have a "rowdy" race gas 496 with iron heads that makes around 720hp at 7400rpm. Runs 9.80s in the 1/4 in a G-body. I'm using ported rectangle port heads and a 775/748lift 288/296@.050 solid roller. 13.5-1 compression, DART singleplane with 1150 Dominator.
Good call, STILLtehPILLAR. He's got a G/SA decal on his window and that's NHRA Stock class. Have to run OEM heads with the casting number and correct year on the head. I'm guessing factory GM 1968 aluminum heads would blow the budget for this build.
What trans does it have, Th400 or Powerglide?
He said TH350
I'd dial a 6.62 1/8 on the first pass and then go down to a 61 or a 60 as the evening went on and hope I didn't sleep on the tree. That car could make some money.
What gear you have in the rear?
Probably 4.10 or 4.30
It appears it needs some square port heads. However I love it.
So basically ur runnin 10.50s?
Remeber 3 weeks ago when I guessed a 10.60? I was off by 5 mph though.
Wet time doid it run
