Question for Cylinder Head gurus

LuvMopars · 10-07-2010, 03:16 PM

If you have a small block stock eliminator engine and you have a choice between two heads, one being about 5cc's larger in the intake runner than the other, but both are the same size in the pushrod pinch area, would there be much difference in the two heads as far as horsepower ?

Are you talking about 894 X and 915 J 2.02?

Yes sir, thats exactly what I'm speaking of. Man, youre reading me like a book ! LOL

more intake runner volume, more power... period

That thinking might be true for brand X heads but the chryslers like velocity not so much as volume. port speed is crucial. ask GTX john. Bigger cc.s does not always mean better. I am currently working with heads that are WAY under spec and they are making alot of good power. Right John?

If your talking Super Stock, velocity yes. Stock, no - stock intake -stock runner- more volume more power... been there
