I just got my fully built motor back yesterday (ge sleeves, piston+rods...). I'm also putting in a sc61. I'm shooting for 480-500 whp. I will be ordering flamenco-t's fuel line kit, what pump should I use? Will the inline that I have work or an in-tank work or do i need those expensive external pumps? Thanks

 

honestly for your goals and setup, i would probably go with an external pump. Running out of fuel can definately cause a problem.

 

actually, you'll be fine w/ a walbro 255.

ive tuned multiple cars that have made more power than your goal on a simple 255 walbro...

 

Correct by the man himself. If Mase says it is possible I assume chances are you will be fine! Never seen huge numbers but I guess it is possible.
