Head/Cam combo problems
Alright so I have a 5.3 LM7 and I have chosen to use either the PRC stage 2.5 5.3 heads or the PRC stage 2.5 LS6 heads. But I don't know what cam to pair with it for a decent power gain I was thinking the MS3 at 112LSA or the 233/239 .595"/.603" with appropriate springs and 1.8's but wasn't sure if the cams would be too big. I don't want to do a custom cam. Can someone give me some advice?

Ported 5.3 heads would be my choice, but with very little chamber work to keep compression up.

I did email him all he said was that the Ls6 2.5 stages would be a best bet for my power goals which is around 400-450 rwhp nothing on a cam even though I asked about it.

I thought the 110 was wider or am I flipping it around? I think the 110 range just gives it a really nice choppy idle and good low end performance

It seems like for a LONG time lots of people were preaching 112 and only 112 lol....I'm running a 115lsa, but with my 255/263 duration I have plenty of overlap

It seems like he's had quite a bit of experience so I wouldn't doubt him at all!
