Hello all, been a while since I've been here but have some new questions. I'm debating on going fuel injection with my 74 and using the 525hp LS3 crate engine from GMP that I had in my 01 Z28. Looking mainly at conversion fuel tanks for the swap such as the Holley direct fits, Aeromotive direct fit, Rick's Tanks, Detroit Speed, etc. and seeing a range of prices from 450-1500 bucks. I've heard about the Holley ones starving and losing pressure when under 1/3 tank during high acceleration/cornering but not necessary from anyone with first hand experience with it. Just curious if you had one of the Holley tanks and had to use a surge tank or something else to keep the pressure consistent.

Anyone have first hand experience?
