Does anyone have an idea how much rwhp a low compression 422 could make? I was thinking on a 6.0 block, .030 overbore, 4.125" crank, about 8.5:1 to 9.0:1 pistons, ported/polished 6.0 heads, and mild cam.

I figure somewhere around 400-450rwhp...

Thanks

 

Well I'm gonna say that an 11.5:1 422ci will make 480rwhp.

So, figure for every point in compression you drop that will be about 2-3% hp.

 

Okay thanks for the reply. Just trying to figure out what exactly I am looking at...
