450 - 500 hp 302, all motor - Page 3

Just follow the AFR engine dyno, but use the victor 5.0 intake or somethin similar to it. Those HP numbers possibly indicate that the AFR heads flow better than Westech had shown? Thats what I used to plug into my sim dyno?

Anyways, 280 cfm will support upto 540 hp if put together right.

300 cfm is kinda high IMO for that kind of power. To me thats like using a bozooka to waste a cockroach. 300 cfm will do the trick but your torques gonna suffer.

i gotta agree. looking at this guys budget 280cfm heads will be probably overkill using 30x ci and a stock or budget bottom end.

if he build a solid 34x ci motor using i could see him using some 280-300cfm heads reasonably with hydraulics.

damn only 106mph n/a? exgmguy has a weight right around there and goes 4-5mph faster with like 50+ less rwhp.

heh cone stall? coan?

How about a 500 plus HP, 289..N/A that will last. Just go to www.cobraautomotive.com/horsepower.htm all at 10.5 Compression ratio. I wonder what they could do with a 302. But you have to spin it.

That would be nice, and that would work, but I don't have the money to buy one outright. Whatever I get, it's going to have to be built from parts that I put together. And for cheap too.

Like a stock rebuilt shortblock. I'd put it together my self if it was all a matter of bolting it together and none of that measuring and cutting the rings to fit and what not. I might do it, but I don't think I could do it for cheaper then buying a rebuilt shortblock. Maybe I could though?

I was going to build another motor and drop it in on a weekend, and then keep my current one as a backup motor.

I just need a head/cam/intake combo that will give me the most out of a 302 bottom end.

if you are doing it yourself why not invest in a stroker kit. they aren't much, can be had for 1500 or less. as long as you stay n/a and reasonable rpms you will be fine with the stock block. you obviously wanted a lot of power, but your original goals were way off for your budget/setup. then you can run some good heads, keep a hydraulic cam and still make good power.
