Default Please help me with my fuel system

I am building a 393 ls1 with the asa hotcam 226/236 .525 .571 (I have 1.85 rr on the exhaust) and livernois stage 1 ls6 heads. I plan on spraying in the near future. And maybe a bigger cam in a year or so. What size injectors should I run? Will 42lbs be good? Also, what are some of the better in tank fuel pumps?
Thanky you
Steve

42's should work fine, but put a set of 60's in it so you never have to worry about a fuel shortage. (that sounds wrong) With a set of 60's you won't run lean at high rpm unless you lose a fuel pump.(sounds better)

If you are running that big of an injector will you smell fuel? A friend of mine used to be big into 5.0 mustangs and he was saying that when he went with 42lbs his car smelled really bad of gas.

Are you spraying a wet or dry shot? Take a look at the Racetronix fuel pump kits.

You'll be fine with the 42s. If you wanted to go a little smaller you could too.
