I have to mention this, the paint job on your car is top notch! She is BEAUTIFUL
Thanks! 👍🏼
Love it thanks for sharing ,I got a Howard's Hydraulic Roller I got to get to work and Start her up it's in the car but I got to get my transmission in also,sounds great 👍
Thank you! I’m very happy with it so far. It has awesome midrange power.
Dang! Lets go for a ride!
Once I get the carb dialed back in I’ll get a couple good driving videos.
Nice, I have the same cam in a 496 68 Chevelle
Thanks! I just checked yours out. That car you have is awesome. I love the 68 Chevelle. It’s my favorite year.
Cool cam.I like the xe 276 hr , I believe it works great in the 396
Is cam good for street
Nice motor 👌
Thank you!
Any piston to valve clearance issues? Are you using flat tops or dome pistons? Thx nice build
Thank you! I used Sealed Power L2242NF 30 Speed Pro dome forged pistons. I did not have any clearance issues with the setup.
Are you using open or closed chamber heads? I have a 402 and a set of 049 heads and looking for piston suggestions@@DadsToyBox
They are open chamber heads. The pistons I used may work. I got the pistons from Summit after they recommended them for my build.
What mufflers are you running? Sounds badass I have a Howard’s in my 496 but haven’t got it dropped in car yet curious about powerband
I have 2” hooker headers and 3” exhaust. The mufflers are some old school warlock racing mufflers but they need to be replaced.
Sounds great! Did you use stock push rods?
Thank you! No I had to use a much heavier push rod. If you are interested I’ll try to find exactly what they were. I had a lighter aftermarket comp cams set in there and the springs started to bend a few of them as I was setting the lash. My machine shop sold me the heavier ones.
@@DadsToyBox Did you go from a flat tappet to a roller? I was wondering if the length of the push rod changed.
Also has the car been to the track since the upgrade? I have a 454 and I'm thinking about upgrading to a roller.
The car had another engine in it when I bought it, a 415 Motown block that was over 900 hp. I bought the 396 block and built it from scratch to be more of a streetable car that could still provide a lot of hp. So I’m not sure on your pushrod length. You could call Summit or Howards and give them your current setup and they could probably give you an answer. So far I love the roller cam and break in was stress free. I have not been to the track with it yet. Only test drove it once and it’s a beast.
Hey I have a question about the blow back what did you use or make for valve cover
I bought the valve covers from someone. They already had the holes cut in them. I added some correct sized AN fittings and ran the hoses to Moroso Breather Tanks. I included the link to the breathers below.

Beautiful car! Sounds good,might be 400hp tho
Thanks! You are probably correct. Hopefully I put it on a dyno one day.
@@DadsToyBox it might be. Only way to know it have it dynoed. I've built a lot of big blocks over the years and it took a lot to build a 454,460,489,496. 396 is just so small. Takes a lot of compression really good aluminum heads and a special solid roller to bring one to 500+ hp. Best I got out of one was a 11.5 :1 30 over a whole lot of money and still only ran a 11:36 in the 1/4 mile in a 68 nova. Lexan windows,roll cage and lot of fiberglass parts. I switched over to a 383 small block and run faster! Go figure! 10:50's
@@DadsToyBox I had a friend that built a 454 with rectangle older heads a 570 lift hydraulic cam edelbrock, Edelbrock intake 800 double pump Holley run and sounded good in a 70 Chevelle. Yanked the front wheels up on the street. I had a 79 Z28 Camaro factory car and gears with an old Saginaw 4 speed in it and a 355 SB w a cheap Summit intake and 443 lift baby cam 10:1flattop summit pistons stock open chamber 882 heads with an old Quadrajet carb on it. We lined em up one night by the time I hit second gear I saw him fade away when I hit 3rd gear he was 10 cars behind! We never did understand it,even to this day! I still have that little engine but in a C 10 truck with Vortec cylinder heads on it and slightly hotter camshaft. It pulls like a monster.
This was the first engine I built. I may stick with small blocks in the future. I’ve heard similar stories like yours. Plus it would be nice to be able to work on the engine once it’s in the car without cussing 😂
@@DadsToyBox Exactly! Lol but mine aren't stories, they are facts! I worked in a performance machine shop from late 88 to 1998. I've done an seen it all. Street race to track and in-between. If you look up some specs you will also so that small blocks put out big power to weight ratio. I've had my fun with big block engines and done it all. I found out the hard way a small rules! I've built some monster big blocks and some monster small blocks. Up to 500 ci small block. Insane results. If I were to tinker again it would def be small block. Like a 421 or 440ish maybe little more lol without the cussing😁😆
Hey whats your idle vacuum looking to see how well this cam will work with power brakes
Around 11.5-12. I have power brakes and they work just fine.
How does this cam do on the street ? I’m building a 396/402 with oval port 215 closed chamber heads and L2240N pistons . Car will have a th350 trans and 3.55 gears
Yes. It does fine for street. That’s pretty much all I use the car for currently. I need to get a different carb for it. I’ve struggled to get the current one dialed in. it’s a little big for my setup for street.
Motor sounds good . Can’t wait til I can get mine together
@@DadsToyBox AED they custom build it to your engine, cars specs. A/F ratio should be perfect right outta the box
I installed an AFR gauge along with a Quick Fuel Brawler 750 and was able to get it dialed in.
Nice car what rad are you running
Thank you! I’m not sure what it is. It was the old radiator that came with the car prior to swapping the engine. It seems to work okay so I’m good with it.
Try smaller jets
Sadly from 2030 on all combustion cars including classics will be banned
from public streets in entire EU and Scandinavia :-( In Germany the
Green Peoples Party gave order to shorten fuel supply from 2025 on by
reducing all conventional fuel stations to only one state operated
central gas station per city or county. Now they even want to slow down
all the gas pumps from 20 litre per minute to 2 litre per minute...From
2027 on in the EU certain car spare parts will be banned too....as
exhaust systems, turbo chargers and even some engine and gearbox
oils...California and New York will do the same from 2027 on.... So no
investments should be done in oil burning cars any longer....They even
created a new kind of crime here, called emissions and smoke crime. :-(
That sounds absolutely horrible. I live in Florida, so no issues like that here.
Screw the crooked politicians that believe this hocus-pocus 💯
That sucks
@@timbeiner2040 as hell, sadly China controls most politicians!
Carb?

what's the cam specs
Hi David. It’s a Howard retrofit hydraulic roller camshaft Advertised Duration 288/294, Lift .618/.618, 112 lobe separation
@@DadsToyBox thanks
Why would you mess with a 396? 454's are a dime a dozen.
A couple reasons. I liked that the 69 Camaro came with a 396. Everyone has 454s because they are a dime a dozen. And I had a 396 to build.
@@DadsToyBox Nothing wrong with that. I have a 496 tall deck in my car and it seems like everyone hates them. Sometimes it just makes sense to use what you have.
@@musclebone7875 just checked yours out. Badass!
@@DadsToyBox thanks bro
