I am wondering what cams makes more power? I have both in my hand right now and I don't know which one to run. I have an 02 Z06 and have seen dozens of Z06's make 435RWHP with the stock heads. Then on the f-bods the G5X3 barely makes 400 while the MS3 makes anywhere from 418-430 and this is with LS1 heads-not LS6 heads? alos what cam is more streetable-I have seen some MS3 dyno graphs and it looks like it gives up alot under 3500rpm. Oh and my G5X3 is a on a 112.

I believe the MS3 will clear the valves and piston but the G5X3/112 will need flycutting.
I've read about a couple of setups clearancing the X3/112 on stock LS1 hads but it is too tight for my liking <.0700

Oh BTW you can make up for lower TQ loss in the MS3 with 4:10's

I saw you have As 5.3's, I think you'll need to flycut for both these cams.

I know I have to flycut but I don't have the AS 5.3 heads anymore-I will be using a stock LS6 head ported by a friend. I'm not too worried about the loss of torque as the Z has a 2.95 first gear ratio BUT I don't want to sacrifice too much-I have to keep the launches down to avoid breaking the independent rear again.

Then it is as stated in my previous post. Call TSP and make sure. Keep your heads unmilled, just port them.

Vortech- What setup do you have now? The MS3 will clear stock heads. If you're having them ported, what size valves and are they going to be milled?

BTW, I daily drive my MS3.

Right now I'm going to be using a LS6 head but with stock valves-they may be Manley but they will be stock sizes. I may mill the heads to get 11.0 and i have no problem flycutting my pistons-i would have had to flycut for the G5X3 on a 112 anyway. I just want the most power and torque and if it was a perfect world I would also like the most average horsepower too! I put the G5X3 on a degree wheel and the MS3 is bigger for sure-I know that. Just was wondering how it would perform on a LS6 instead of a LS1. The G5X3 works very well with cam only Z06's. AND the MS3 works really well on cam only LS1's-but it's all about the package.

I think the G5X3 works with stock heads. I have 2 friends with that cam. One of the guys Firehawk dynoed 427rwhp with stock heads, boltons,and his own tune. they did no modifications that I know of, as they installed the cams themselves.

yes you are right greggles, the G5X3 DOES work with stock heads, but on a 114 LSA. The 112 G5X3 requires flycutting the pistons.....
