im building up a lt1 cam, ported heads and ported tpi on my lil305

i would like to use a stock 350 prom to start with to get it to run but i only have #19 injectors

i have the stock #28 injectors out of my 2002 and they are rated at 60 lbs of pressure

at 40 lbs of pressure these injectors would flow just over 22 lbs

would this be exceptable?

thanks

I think I'd just stick with the 305 chip, and tune from there...I don't think the LT1 cam compensates for 45 cubic inches.

 

or would it be better to use a 305 manual bin and it to auto so i have a closer spark and fuel curve then now and still be a 305

thisnk thats the way to go?

 

Probably a better suited question for the PROM board, do you know if there is a difference in the curves between the auto and manual? I'd assume there's things in a manual bin you wouldn't want in the auto....I'd still tune with what I had, especially if you're just going to make the spark curve more aggressive and add more fuel to each table.
