Fantastic, it'd be even more responsive on a set of throttle bodies! Please don't tell me that it was mated to an automatic gearbox, as an engine like this only deserves a manual?
No on the pump gas unless you have aluminum heads or build it with weak compression. You could potentially run enough overlap to get away with is as well as drop some timing I guess. My 302 was about 6500 with parts and machine work.
hey man I'm actually building the same thing but I'm using a edelbrock sy1. I'm looking for that exact carburetor. You wouldn't know where I could find one would you? 830cfm just like that.
Hey Steve I've got the carb in the video I bought the motor from Bill a couple years ago the carb is sitting on the shelf I went with FI instead let me know if you want it we can make a deal on it
Forget the myth that a small engine or one with a short stroke is somehow more responsive than a larger engine of the same type this is NOT true.... How can it not be true? Say you have this engine and a 454 inch small block Chevy. Both of them are about the same compression ratio etc, both cranks, rods and pistons weigh about the same amount but the 454 has 150 more cubic inches pushing the same amount of inertia. Result, larger not smaller engine changes speed more rapidly. Check out 454 small block idle and rev to see for yourself. That engine isn't just turning a flexplate but also a dyno drive plate and absorber as well.

Great job! I must acknowledge that all engines will rev quick with just a flex plate. I have ridden behind a 307 in a Camaro, Let em tell ya, it weren’t slow, sluggish, or quiet. It’d do 40 foot tire smokes with both tires....4 spd trans. M21 or m22. 20+ years ago. In my opinion, idle to 4000rpm is torque, 4000 to 8000 is horsepower. Kids dad built the car, claimed 400hp.....who knows? At drag strip it’d do 13.00 flat. I’m guessing hp was closer to 350.
It would be more in the range of 308 or so, 350 is same bore, but longer stroke if it's .30 over is 5 cube then you can assume it plays a slightly larger role with a smaller stroke
I've never really cared for the sound of most 302's, but this one sounds a little different. the one thing about them that I did always like is the quick revs. when you flashed 7000 rpm with ease.....nice
ihateliberals my dad's 302 is at nearly 600hp and it'll do 10,000rpm with the forged steel rods, if he uses aluminum rods instead he'll be getting 12,000+
andrew rey. With a 4.30" bore and a 3" stroke crank it would be 307ish cubic inches. With a 3.25" stroke crank and a 4.30 bore you would get 332 ci. The 302 chevy has a tiny stroke and a big bore.
OK so I've never seen a Ford 302 with headers that appear to be coming of a 350 small block Chevy head setup. Looks like a small block Chevy to me not w Ford. And it's orange? Somethings saying Chevy to me. But whatever what do I know...
You put the rest of that together with a transmission hanging off the back of it and guess what ? That funny little throttle crack you do you won't be able to do anymore the ONLY reason you can do it is because you have NOTHING connected to the back of the motor ...

Never seen SBC stainless steel heads before… ain’t it sweet how quick they rev with just a flex-plate, no weight or accessories to slow it down.
Listen how quick the rpm gets up there , they would call them giant KILLER'S back in the day!
A smogged 305 will have throttle response just like that. Bolt a 40 Lb. Flywheel, or a full torque converter on it. There is a difference.

Steve Tringale who cares he is not making a oscar worthy movie! Enjoy that sound
Look like a set of worked cast heads to me
how do you get it to rev so fast? is it because theres nothing behind it, ie a trans?
+theGREEK7887
Some ways to get an engine to rev faster is a shorter throw crank, lighter rods and pistons and stiffer valve springs.
a shorter throw crank would change the engine size
vinnie steele yes, a 302 sbf is basically a destroker, allows a longer rod which affects dwell time and let's it rev high
I meant to put sbc to differentiate from ford, as it's basically a destroked 327 which is a destroked 350 being as they all have 4 inch bores, whoops
Tj Skinner a boss 302 will out rev any chevy 302 anyday!
I had the 307 you dont want. This is the 307 you DO WANT. 😁
what cam?
have a 1965 327 block and a 283 still crank.what kinda pistons and rods did you use?350 0r 327?thanks/
You have to use 327 to get the right compression height.
You can use 6" rods with custom pistons. It's been done plenty of times and all the piston manufacturers have a set on hand for the combo.
Sounds better without the mufflers in my opinion. Nice sounding machine either way though.
