You're not going to do the mod to the big block we talked about?

I was gonna but until I know what I have I figured I would focus on fuel. I know my old setup was restrictive.

My "mod" for this weekend was to replace the intank electric pump in the 87. Even though its carb'd I still get the same joy as efi LOL. Anyway, that pumps been in there for nearly 300k miles! Pump was still working but I was running out of fuel after the 1/8 on the track. I got it apart and the sock was dirty and totally sucked up like you'd vacuumed a beer can. Safe to say I think I found the culprit. Went ahead and changed the pump anyway.

Are you using a returnless setup? I have an efi pump with a Keith black regulator. Works awesome.

Mine is stock lg4 carb set up. It has a very small 5psi electric pump in the tank.. 3/8s line to the manual pump and a 5/16 return. I have a 120gph carter pump on the engine itself.
