what's my compression & how long will this setup last? Shortblock has about 500 miles on it...
347ci
LS6 block
Polished crank
Ross 3.905 4cc relief pistons
Probe Ultralight 6.125" Forged I beam Rods-Doweled-ARP 7/16 Rod bolts
Diamond Rings Gapped @ .029 and .032
King Alecular Rod Bearings
Clevite 3/4 Groove Main Bearings
Clevite Cam Bearings
I'll probably reuse the Katech/CNC ported 241 heads with ARP hex bolts. Probably use a thicker head gasket (something over .050). I think I'll reuse my Comp Cam. It's mild. The specs I'm not sure (is there anyway to find out what they are???)... close to a 22x/22x, .581, 113 or 114 LSA. LS6 intake (I might switch to a FAST). Long tube headers, catted, & GMMG. Running through an m6 w/ stock 3.42 gears.
About how much compression would I be looking at? Should I go with highly dished pistons or different heads? I know it would be wise & make more power with FI, but for the extra money is it worth it trying to lower compression a notch, for example like from 10.0:1 to a 9.0:1?
How many miles will this setup last, without blowing the motor or having to change rings, throwing rods, and all that bad stuff? Looking to run about 5-10 PSI. It will be a daily driver & rarely see the track. I know to keep careful with the drivetrain. I hear good things about meth injection. Will this help lengthen the life? I can only find 91 octane around here so meth is probably a good thing for me? Also I'm sure a good tune will help.
Turbo or Supercharger? With it being a daily driver & wanting to be consistent, supercharger is probably my best bet right? Procharger I'm guessing? I heard a lot about turbo lag & that supercharger would be better for the street?
