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
 
2psi sound kinda low to me, their cheap swap it out?

How do you like that 427 tall deck? I have 2 in storage and am thinking about building one to drop in my k5, any thoughts? sorry for the hi-jack.
 
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.
 
Yea car heads seem to be the way to go if you want more than low/mid power. 10mpg!? I dont think my 350s doin' much better than that! Got any idea of your power out put, tourqe/horse's? What mods you runnin? Thanks just tryin' to got brain ticklers.
 
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.
