My motor is finally coming together and I need to know which injectors to go with, SVO #30 or #36. Here are the specs of my motor:

Forged 377 bottom end (350 block)
Miniram II
AS&M 58mm TB
Brodix -10 heads (flow 303/222 @ .600 lift and 307/229 @ .700 lift)
Xtreme Engergy solid roller 242/248 .608/.615 lift 112 ls
Pro-Torque 3200 converter

The rpm range on the cam is 2500-6900 so I don't want the motor to run out of fuel up there. I know the SVO injectors are underrated so I thought the #30 should be ok. Any thoughts?

------------------
87 IROC-Z 305 TPI gears, exhaust, converter
14.70 at 94.1 mph
Minirammed 377 for spring

 

30s are ok may be still to big if youuse a stok cpu
i would go with 24 or 28.
if your wondering about who makes this sise
lucous does

 

Get ahold of the Desttop Dyno program and run your engine. My buddy down the block runs a drag car, and when he build his last engine, he had it dynoed. The Desttop program was only 8 hp off from the actual dyno run. The other part of what what you need can be found at the MSD web site. The formulas to calculate injector size. Also to convert the flow of an injector when changing fuel pressure. (The SVO are rated at 37 psi, and GM uses about 43.5 psi.)

 

i have SVO #30 plus mine is not running just yet so i dont know yet either.
