Default picking a cam

ok my set up is a basically stock efi chevy 350 and ive heard that once you get into the past a 501 cam the fuel injector wont pump enough fuel to keep the motor at an idle true any suggestions on cams would be nice

IMO> it wont work........ TBI's dont have much of a tuning window as it is, now if you had port injection, yes but with that the old TBI set up of yester-year, your pretty much stuck to a RV cam at the most.

That should have answered it for you.

Tbi's are not performance friendly.

A nice exhaust will give it a good sound and save you lots of money and headache.[/quote]
