Fuel Injectors

[Pace1989]

Is there any "rule of thumb" when picking injectors? I'm thinking of the 009's but am hesitant because I'm not sure of how much injector I need. TA49, THDP, cat back, roller cam, ported heads, forged pistons, recent rebuild but still have stock replacement injectors. Thanks,

Hello Ken,

Learned something resently, take bigger injectors than you was thinking of!
In your case i would say at least MSD 50?s with matching chip.

With your mods so far, I'd go for the MSD 50's also. 50's are as big as you can go with the stock ECM, otherwise it has to be modded or crapped completely for a DFI.
The 50's cost more, but flow very linearly and are easier for programmers to program for, if you get a matching chip for them, they will idle just like your stock ones, then you'll have room to grow.
