If you have done a 5.0 HO conversion/swap you NEED a HO fuel pump

Heh, you got to it before I finished my edits - I am buttstuff about posting material that reads a certain way (properly) - lol.
I'll get you that spreadsheet - where to send it to? It's actually a modified sheet I got from the web somewhere - you'll like it - there are other tabs for doing blown engine calcs.
Funny, I was using a 155lph pump w/Boost-a-pump but I used a Mustang kit and the sock did not reach the bottom of the tank - thus I would uncover it at the track unless I had like 1/2 tank - very annoying. I also had a leak at the filler neck that prevented me from filling the tank - ever. I got a 190lph Cougar/Bird specific kit that someone provided a link to here (this is what makes a site like this great) and recently replaced the 155lph (anybody want the old pump?). Now I can turn down the BAP to about 20% and see no drop-off in fuel pressure (I log fuel pressure, boost, AFR & 16 other engine parameters using the TwEEcer).
