my dad just put a 383 motor in his 95 chevy pickup and He needs help. He is running lean i need to know how to get more fuel to his motor its a throttle body. Can anyone help me. Next year he after he works out the bugs he wants to add a blower to it. Thanks

 

i think an adjustable fuel pressure regulator would be the best place to start, i've heard they can come with 9-13psi(or is it 11-13psi) from the factory. even at 11-13 theres a 20% difference in how much fuel you might be getting, and i've heard they run best at 13.5-14psi

or you could try to find injectors with a higher flow rate. or maybe just find somewhere to send out your current ones to be ultrasonicly cleaned and checked for flowrates.

my last idea would be to try a chip, so that it just commands more fuel.

 

The factory one is not adjustedable right? I'll tell him to look into one. Can you tell me about where it is? Thanks for all your help

 

He already has a performance chip in the truck.
