i might have to dyno test them and see how much of a difference they make
do you guys think the 243's, MS3 and FAST intake would get me to 425whp? and 11.50's? i was thinking of possibly getting a custom ground cam instead of the ms3 too

yeah good point although the fast intake will probably be in the distant future, i always have my truck intake too if it will fit under my hood

I think you will have no prob going 11.50 with that combo.
This setup has been close to your goals with a junk tune on the car hits rev limiter 2nd to 3rd shift and holds it bad, and very fat.
I think with my tune corrected I will go 11.50 no prob.
Car is 3400LB also
05 LQ4 stock long block
571/573 on a 112LSA
LS9 head gaskets w/ EBAY head studs
LS9 valve springs
All camaro acc. intake manifold, throttle body, front pullies, injectors etc
4l60e w/ vigalante 3600 stall
3.73 gear

I wouldn't see any reason it wouldn't, hold for the LS1 intake. My heavy pig ran an 1/8th mile equivalent of 11.30s in the 1/4 with a similar setup plus a coulple hundred pounds. That intake will hold the car back on the top end though. I wouldn't run an ms3 in a stock cube 6.0, 7.75 degrees of overlap if you go with the 112lsa is going to idle like shyyytt. My 230/238 112 lsa cam only had 5.5 degrees of overlap and 19 more to soak it up and you heard how choppy that was. On top of that an MS3 is going to be pretty hard on valve springs especially beehives, you should really have doubles for that cam. Stick to TSPs 233/239 112-114 lsa or an EPS 226/234 113 lsa.

if i ran a different LSA on the ms3 think i could get away with it? i plan on getting the heads ported and a FAST intake down the road so thats why i was gonna put a kinda-too-big cam in it now haha
what i should be doing is building a big rig for the upcoming season of 18-wheeler racing at winterport hahahaha

you can hand port yourself with some 60 grit sand paper and finish off with some 1000 to smooth off. for 400 i can port and finish off with hand port. maybe even less.

bought some 243's yesterday, they should be here friday, i think i might go with a .054" compressed thickness mls gasket and get the heads shaved .025-.030"
can anybody tell me what compression ratio it would end up being for .025 and .030
the bottom end is stock lq4 and the heads will have stock size combustion chambers
