What size injectors should I use?
 

New rebuild-306, Forged pistons, Eagle rods, stock crank, Typhoon intake ('cause I got one), 65mm T.B.&70mm "cobra" air meter ('cause I got 'em), AFR 165 heads, Trick flow #1 cam (221*/225*@.050 .530/.542 lift W/ my 1.7 RR's).
Can I run stockers or step up, I've told '93 meter is calibrated for 19#'ers? Cobra CPU was calibrated for 24's?, but I'm using an A9L

A9L and Cobra MAM = 19 #ers

I personaly would run 24# injectors with that set-up. You can either get the 24#electronics for the cobra MAM or get an entirely new meter. I run the C&L MAM and it works very well.
