That is true 73Nova73. Lots of interchangeable parts. But are you planning on building a high HP motor with stock parts from other motors? Once you start on that HP search it's TEA heads, and Cally crank, and JE forged slugs, and a Comp custom grind cam, Eagle rods, Canton pan, BG Carb and so on. Now that I think about it...I think I have 2 Ford parts in my motor. Oops. The block and the oil pump. And the block is Ford Motorsport. As far as a Ford 302 vs. a Chevy 302? You would need to build identical chassis, same gearing, same weight and see how they matched up. And Supernova..the Chevy 290 HP 302 made it's max power @ 5800 RPM. From there on up in RPM the power curve goes straight down. www.carnut.com/specs/gen/chv67.htmlRon

You dont NEED all aftermarket peices to make a high hp motor, I read in a magazine on a build up of a 600hp 307 with stock crank and rods.And i read elsewhere that the 302 made its peak hp at 7800.

I wasnt the one that mention the 290hp rating.
My car's power starts to decend after around 6,000-6,500 RPM's. Because my cam and all is set for low - mid range power. Since my gearing is made for that.

I cant remember the specs on the original 302 cam but i know it would go further than 5800.

It would seem like it anyway. Since they had high RPM's.

Yeah, because with the 3" stroke, that motor would wind up QUICK, and with fairly low gears(3.73) it was went for higher rpm use.

Did you klick on that link I included in my post? Sure you could spin it higher, but it would make no sense. Once you go past peak power, the car "lays down". Ask any drag racer you know. Look at any Dyno sheet. When racing, you launch the car 500-600 RPM below peak torque, and shift 100-200 RPM after peak power. To make 2 HP per cubic inch is VERY hard to do. If you milled the heads 1/8 of an inch to bring your compression up to 16/1. But even then, you would need some very good parts to do it. Stock parts can't handle it. Here is a Dyno sheet of a stroked 302 www.rfedd.bigstep.com/Images/victordyno.JPG After peak (7200) it just falls off. That motor launches on a T/B at 5200 (600 below peak torque, and allows the converter (5800) to flash up) and shifts via Shifnoid at 7400 (200 RPM past peak power). That keeps it dead nuts in the power band, which is where you want to be. The last thing to consider are the valve springs. Without the right springs, they would go into bind, and valve float would occur. Ron

what i meant by "it would go further than 5800" is that the power band would, obvuisly the engine can rev past 5800 hell, it could rev 12000 if you had the balls to do it.

and taking an 1/8 of an inch off the heads is not the only way to make 2hp per cu. in., stock rods and crank would not be able to handle the kind of commpresion. I cant remeber the specs on the engine but the only thing stock was the block crank and rods.

and yes, valve float is very bad.

Yes any engine will rev high, if you dont have a fear of blowing your engine. I meant, it looks like the 302 would have power all the way up to around 8k before it dropped off at least....just because they are naturally high reving engines.

Does anyone know what a Formula 1 car revs to? I think if memory serves those 1/2 million dollar motors rev to about 10K.
