probably picking up an lt1 this weekend for the 89. Im wondering what kinda fuel pressure and amount this thing needs to run? im probably gonna bore it out at least. possibly stroke it as well. i know it all depends how much i do and what not, but lets just say ive boosted the hell out of it, and gotten the LIMIT of the CID of this thing.. what kinda fuel am i gonna be needing? and can it still be in tank? I was hopeing the TPI pump would work out for me. or another pump that i can put in its place that maybe puts out more. i can always get a return regulator.

haters need not answer this.. you know who you are..

 

fuel pressure should be around 40-60psi.Yes it still can be in tank.

 

how much do those TPI pumps put out?
