Re: 302 chevy

thats why you run a 302 with a 4 speed [that was the only way you got em ] 4.10s or 4.56 gears and a heavy foot

hear the boss 302 was an even worse street motor - but was heavenly in the upper revs

Re: 302 chevy

4:56? That is a highway gear! 5:13 is the minimum. 5:57 or 6:17 are even more fun.

Re: 302 chevy

The D/MP Camaro at Bowling Green was packing 6.17's and a flywheel that was so heavy it may have been made from depleated uranium.

Re: 302 chevy

and none of these engines will make 500 hp at 6000 rpm at 302 cubes.

Actually if you made 1.5 ft/lbs per cubic inch you would make a little over 500hp at 6000rpm. ;)

Begging your pardon, fine junkie, but peak torque rpm does not coincide with peak power rpm, it is on a downslope well before peak hp. So a peak 1.5 lb-ft 302 will not retain the torque to make a peak power of 500 hp at 6000 rpm. However, a 302 that makes peak torque at 6000, and makes a 1.5 lb-ft per inch will make over 500 hp at 6000, and would peak at about 570 hp at over 7500 rpm, but there are not too many engines like that around.

I think you forgot what you said, so lets quote it again.

and none of these engines will make 500 hp at 6000 rpm at 302 cubes.

All I'm saying is if your making 1.5ft/lbs per cubic inch with a 302 at 6000rpm you'll make over 500hp. Sure you might make more power above that, but then that might be the cut off point to. Either way it all depends on how the motor was built.

That's pretty clear, a very good race engine might hit the 500 hp at 6000 mark on the way up, but that isn't what we were discussing here, which is a 500 hp engine. I was telling the guy what it take rpm wise to make the power numbers he was suggesting the engine makes.
It sure isn't any 302 that makes peak power at 6000.

Well the cat is out of the bag and Nelson Racing Engines does it again. Here is a Video of a STOCK DZ302 on the dyno, spinning 8500rpm and making 530hp.

I'm waiting for DG's response. ;)

Re: 302 chevy

a flat tappet, pressed steel rocker motor ain't going to 8500rpm with stock valves or springs... least it won't be there long...

Sorry guys... just ain't so... Chad... your dad ain't going to tell you he did that either... 7500 maybe... but it's got something in the Valvetrain...

BIG RPM ( over 8k ) is Hard like 14 mo fo's on crack... trust me... anyone can free wing a motor to the moon... but you gots to have Piston to Valve Clearence...and remember that Compression thing we talked about... those Valve pockets gots to be there... and NONE of this is possible with a Aluminum rod motor... ( I've had one... lasted the better part of a weekend ).... It's all gots to be light and Tight...

Re: 302 chevy

you buying aluminum rods at wal mart again, turk ?
I lust for a set of BME Alu rods

[KeithTurk]

Re: 302 chevy

You building a pro mod motor?

Keep that junk out of anything you want to live.... Aluminum rods are for Drag racing ONLY... ain't worth doddley squat on the street or any type of "real" endurance racing... ( and Yep I've still got an aluminum rod motor that I have and will use at Maxton... but I'll never trust the rods )

Re: 302 chevy

I've picked up lots of aluminum in my years at the drag strip.

They work great until they don't.

I love to watch what is turning into ricer dream math (517 @ 6000) - but...

Go back to where this thread started and think about what is really being asked. No, I don't think you want a 302 in a damn near 2 ton Monte when you can go 383 or 406 for cheap and enjoy the torque. It's a street car.

i'm obviously not going to put it in the monte. thats getting a 383. the 302 is just too good of a deal to pass up....and i found an rx7 ;D
