however after further reading and reviewing with my builder/mechanic it is obvious I had chosen a poor source for the engine. I accept responsibility and basically want everyone to know where I got it and I wouldn't recommend them. Basically I paid $1,200.00 for a block..ouch. Just a lesson for all doing a swap do your homework before buying your parts decide how much HP you want and build from there I have LEARNED a lot from timz my mechanic...wished I would have met him sooner.
