I gotta vortec 4.3 wanna swap with the newer ecotec pistons since they the same motors pretty much
Heard ecotec vortex vtec they all the same
motors I got all the parts outta all of them the
pistons are a little loose got the heads back on
was missing 3 of the 20 bolts but left them out
on the middle truck turns over but wont start I
know the bolts are missing but it should still run
