any one

Works just fine. You just need to make sure to use the GSR rods/crank together and you'll be fine.

fo sho

any one know if there is any cons/pros if i go turbo

depends on what else you put in the motor....

leroyb

well stock head, arp head studs,?

Cons:
Less torque out of boost

Pros:
You get to run the GSR rod bearings (narrower and made of a lot better material than LS bearings. Can sustain high RPM much better than the LS bearings)
Shorter stroke means theoretical slightly higher RPM capability (arguable, though, as many people will turn an LSV pretty high)
Stronger connecting rods
Larger rod bolts (9 mm vs 8 mm)

o cool answered all my q's i had

Jimster480

stock LS pistons and LS head? Then you should be fine. And everything that RyanA said. But you cant raelly turn a LSV that high unless its built for over-reving. Still you cant really take it up that high without risking it. Usually people kill their LSV's by revving them to 8k+

yea im just doing a straigh ls no lsv for me, there cool and all but is a lil too much of a build for me
