What size fuel injectors for the following combo?
EFI 540 BBC with 335 AFR heads, 10.8 compression, Super Vic intake, solid roller cam 262/266 @ .050 .735.714 lift 112 LSA, with 2 1/4" headers. It's a street motor only.

somewhere near 60 - 65 lbs/hr. 60 is good for 750 HP, 65 is good for 800.

there's a lot of injector calculators out there, try http://www.rceng.com/technical.aspx or google up one you like better. they all work off the same formula which the RC site shows you.
