302 cid

Is it possible to purchase a crate 302 anywhere or do you just have to find on old one.

Also i know you can stroke/destroke engines and such to get the desired cubic inches, but if you do this do you still get a high rev engine.

Your import must be really fast cause you were haulin *** when i passed you in my camaro.

Re: 302 cid

I have a complete '66, 283 that I'm either going to make a 292 or a 301 out of it depending on cost and availability of pistons!

I'm gonna shift her at 8,000 or above just for the fun of it!

I dearly loved my old junk301 from way back then!

Re: 302 cid

I would guess if you could find a 350 four bolt truck block and a crank with a 3" stroke, you would be well on your way. Scat makes a crank with those specs, but I can't speak to how rugged it is.

Guys, what would you do as far as crank, pistons, cam, and heads?

Re: 302 cid

A 302 is relatively gutless at low rpm. To get off the line you rev it up and feather the Clutch. The 3" Stoke X 4" Bore Engine was basically put together using existing GM Parts to meet the 303ci max displacement Trans/AM Rules. It's relatively cheap and easy to built a small journal 302 using the 3" 283 Crank, pre-68 327 block top it off with a Holley 750Dp and Edelbrock RPM Performer Intake. Today, I would use Vortec heads rather then the Fuelie.

I personally prefer the 68 327 for a SBC Screamer. The extra 1/4" stroke and displacement can put the combination up to 425 Hp with notably more torque running a Mechanical Cam.

None of that is true.

Re: 302 cid

My invitation is to anyone interested, drop by Clovis CA. I will take you for a ride around town and then tell me what you think.

They will never run like a BB for torque, but they can run and drive just as good as any stock 327. They were never the fastest car, but the factory tuned them for smog. I agree with Z15, if tuned with exhaust manifolds and a poor timing curve.

I actually talked to a guy that wanted to buy a '69 Z/28 but was worried because he had heard you had to rev them to like 3000 RPM just to get moving from a stop. Who makes up this stuff?

Having said that, why would anyone build a 302 if you don't have the Z/28 to put it into? Build a 350 or 383 like everyone else.

Re: 302 cid

My first 69, which I bought in 1989 after graduation was a bad mofo. It had a 302 with 12.5:1 piston, can't remember the cam, but no one could beat me. I had 4.56 rea end and that puppy would launch. I never ran it down the drag strip, just old blacktops, so I have no idea what she ran. I have a 383 now about 450ish horse and that 302 was every bit as fast, if not a smidgin quicker.

69 x-11..LS1, 420.88 horse to the tires,750 Holley Ultra DP, Torquer V2, darksides headers, PRC heads, 10.8:1 compression, forged bottom end, 5 speed. 2008 King Ranch F150 4x4.

Re: 302 cid

Tisk! Tisk! Were did I say the 302 was not FAST, if you want to drive around looking for Hi-Octane to feed 12.1:1 Compression and run 3:73's or 4.56's that's your bag. I personally prefer a 600Hp BBC HWY Cannonball with 3.31's or 3.08's that will burn todays gasoline.

If you think a screaming SBC is FAST on the Street or Strip try shifting a 625Hp BBC at 7000rpm with 4.10's through the quarter. Of course you could add NOS...etc but it's NOT my bag.

Re: 302 cid

There you go, a crate CE 302!

There's two ways to drive a 301/302, imho.

3.73 or 4.10 gears and dumping the clutch and flat getting w/ it OR

3.31 road gears and gently rolling her outta the hole until she hit's about 3500 and get's as the 2-stroke guys say "up on the pipe" and then nail her, then shift at 7,000 or higher and repeat!

It's a real hoot up about 7500 or until the points float!
