bosch3 injectors?

so let me start with some basic things I can do while waint for my new fuel assembly to come in. I am/was rebuilding a 383, and giving it a new intake, cam and heads. think the next step was a set of injectors?

from what I hear these Bosch 3's are the way to go? google search to find a matched set?

...

I want to finish this build and make this car my daily driver. can the stock exhaust manifold stay on there or does it need to be replaced too?

Your call on the exhaust. I think the stock l98 system is restrictive.

........ The stock L98 exhaust manifolds are pretty restrictive with 350ci ... your 383 will be begging for long tube headers .............

1 3/4" longtubes will give you the best performance. Check out ARH headers.

this thing is telling me I need 35lb/hr fuel injectors? is this correct for a 383?

383ci, and about 450flywheel horsepower? - or I am guestimating around that much horsepower?

thanks again guys

let me ask another dumb qustion:

I thought the flow rate of the fuel pump was 255lb/hr? so that would make a max flow rate of about 32-35lbs/hr for my injectors assuming I had a BSFC of .45 - .5 or so?

am I doing the math right? so does that mean at WOT I might actually need a high-flow fuel pump?

If you call Jon at FIC he will spec an injector and help you set the fuel flow rate in PSI.
Slap an adjustable FPR and long tube headers.
Then get some data logs and get mseven or pcmforless to burn you a chip.
You'll be amazed at the end result.
