lm7 heads to new 5.3 799 benefits?

[skeet]

not worth it, youd have to mill them to at lease .030 keep the stock compression ratio of the 5.3.. yes they do flow alittle better but for a NA setup id find another route, now forced induction yeah it would be worth it.

He said he would get them milled...... So I say yes its worth it. Prolly see a nice bump in power.

well duh, ok then explain to me where will he gain from?, it will take .030 to get back to stock compression stock compression on a lm7 is what? 9.5:1 ? what gains are gonna be had?

so explain to me where the bump in power is?

more air in+more fuel in=the powa out

For the amount of money spent I don't think the gain would be worth the money spent with not being able to raise compression any. Any decient porting and ect will be 700+ alone. Then you still have the 250+ for the heads. I'd put my money toward a head that had a smaller chamber to begin with to raise compression. Could pick up so pretty nice heads that will help much more than the rout currently planned

I picked up my Patriot stage 2 243's with 59cc chambers for $700. There is deals to be had if you look around.

so your heads are gonna pull more air and fuel ? without changing anything else?
