well i finally found out what was wrong..everything..rod bearings were too small, crank was way out of spec, main bearings were wrong size as well..just a very very bad builder..also the rods were supposedly shot peened..they weren't..he did put the correct pistons on the ls rods..but he didnt use arp rod bolts..which obviously would of screwed me over since i thought i could easily hit 8000rpms..so all in all..this guy screwed me over..and i will try to get money back from this guy..im gettin pics and have receipt for what he did..or i should say didnt..do..and thanks to the guys at 2nrwerks they are trying everything to get this car back on the road in good running conditon..thanks a lot...
