    I just got a fuel pressure gauge and at start up it showed 7 psi but after warm up it only shows 2 psi. I assume that means the pump is atking a crap but you know what can happen when some one assumes.:D

    I like it. Mine is stock for the most part. It has good low end TQ and gives me 10 mpg. So I don't have any complaints. I have been told thou that a good set of car head really help the motor breath.

    The hp/tq numbers I have seen vary a lot depending on the year of the motor, but mine was out of a 1986 gmc 7000. The HP was 400 and the TQ was 500 or 550 I think. The only real mods I have done is a Holley 770 street avenger, changed out the distributer for one with out governs, and headers.
