Will this be a good setup? I'm buying a forged 347 shortblock that has 500 miles on it.
Here is it's setup:
-LS6 Block
-Polished GM Crank
-Probe Ultralight 6.125" Forged I beam Rods-Doweled-ARP 7/16 Rod bolts
-Ross 3.905 Forged Pistons 4cc Reliefs
-Diamond Rings Gapped @ .029 and .032
-King Alecular Rod Bearings
-Clevite 3/4 Groove Main Bearings
-Clevite Cam Bearings
I'm eventually going to be adding FI to it. The cam & heads I have in my car right now I'm thinking about re-using. Comp Cams 224/228 .581 about 113 or 114 LSA. CNC ported 241 heads. I'm not sure what rockers are in there, or springs for that matter. I am going to buy new lifters. Possibly even buy a different, used cam that will suit my application better. If I get a different cam, I'll probably end up getting different rockers & springs (of course).
My question is, what do you think about boost for this shortblock and re-using my heads & cam? I might have the heads decked when it's all apart. What kind of compression would I be looking at? I have no idea what size head gasket is being used right now, but going thicker will help for boost application correct?

Well is it 4cc or -4cc pistons, Your better off with a -cc piston I believe but maybe wrong. Others will post up.
Everything else looks good, I've got brand new comp lifters and a turbo cam for sale if you do buy this motor.
