Re: Engine Starves for Fuel When I Hit Second Gear

If you find it is the pump, try one of the Carter mechanical high performance pumps. I have had much better luck with them over the Holley pumps.

I also beg to differ about 3/8" line being needed. I don't know what GM put on trucks stock, but i have seenn plenty of people go 12's on 5/16 line---although i personally don't recommend it, because i'd rather know for sure fuel is high in supply and getting to the engine. Its just simple flow principles on the volume delivered vs volume needed to feed an engine. Just a FYI

a 350 will also run with a 300cfm carb but just because you can doesnt mean you should or that its proper.

Agreed, but i think you see what i am saying too. I will always recomend 3/8 for any performance application, and i think we are in agreeance on that. I was just pointing out that it is not 100% neccesary---especially me not knowing what is equipped stock on GM trucks.---Gotta remember, im the odd guy here, LOL.

Re: Engine Starves for Fuel When I Hit Second Gear

lol i left out a smiley there. yea its amazing what will work in some cases and completely fail in others. some of the heaps i have seen come into shops and you just look scared to touch anything but it drove in. I always sit and think if mine looked like that it wouldnt have made it out of the driveway
