Im piecing together a 383 LT1 setup and am trying to figure out how i should go about fueling this bad boy.

Heres some specs:

383ci
circa 10.7:1 CR
1.5 RR's
230/236 576/572 113 lsa custom grind cam
stock casting ported/polished heads
and the infamous comp 918's

M6 car
4.10 rear

I guess my real question is can i stick with the stock injectors and fuel pump or is this motor going to want more than what the stock stuff can dish out? If i have to upgrade.. What size injectors would be best and what fuel pump should i be looking for?

Thanks

just put some SVO 30's in it and leave the stock pump if u wanna do pump go walbro 255 youll be set also do ur filter and check ur regulator make sure its good still

Just do the Racetronix plug n play kit. That will support 600rw.

32's should be fine as well.

I run the stock pump (Almost 13 years old) and 30lbers in my set up...My cam is a 226/234 and is a wee bit smaller in lift, though...When the stocker quits I'm going to go with the Racetronix plug and play set like Speed Density suggests, but I think the stock and 32s or 36s would be fine for now...

I would do 30lbers and a racetronics kit if it were me

but if it were me I also wouldnt put that cam in a 383

well good thing my thread was not about asking YOU what cam i should put in my car. that cam was specced by a speed shop in my area with my goals and car in mind that has built and raced more cars then they know what to do with. thanks for your insight and answer to my original question though.
