lm7 heads to new 5.3 799 benefits?

[beingblueeyes]

what would the power gain be by going to a set of 799 (milled down to keep stock CR) with the mods i have (link in sig)
would it be worth 600-700 total to do it (heads/machine work/valve springs/gaskets/head bolts/ls7 lifters because i was there)

Yes it'd be worth it.

Aren't they the same as 243's?

[Frenchy]

Yep

thanks Frenchy, ill put them on my wish list then

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
