November 29, 2010 0 By Project FD So before receiving the engine it was still a 50/50 chance that I wound up with a very late production LS1 block or got lucky and received a LS6 end of life block. Sure enough we got lucky and wound up with an LS6 block! LS6 V8 vs 13B-REW Rotary Project FD: The Rebirth Engine Bay Prep
