I believe those are the specs for your cam, & with that I would guess somewhere in the upper 13s lower 14s.

Re: What should this build bring?

I was hoping a little more lol my lt1 with bolt ons and a dyno tune made 258whp 330wtq best 1/8 I could do was 8.7 but it has issue with tranny wouldn't shift into 3 at wot.Then the 10 bolt took a dump lol.I was thinking this engine would bring near 280 whp it's alil lighter then the 4th gens.Plus I took some weight out of the iroc! A/c is completely gone along with some other things lol.
