Hi All,

I've found someone locally who will dyno-tune my '96 LT1. Prior to the $500.00 it's going to cost me, I want to be sure my injectors are optimally sized. The two mods I think may affect injector sizing are 1.6 Roller Rockers and Muffler Eliminators.

Currently, I have 24 LB, Bosch III injectors from FIC. I am wondering if slightly larger injectors will yield slightly higher performance... maybe 30 pounders?

Your input will be appreciated!

No. Keep what you have. You maybe gained 10-15 hp with roller rockers and muffler elims, not nearly enough to justify going up in size.

Agreed. The 24 lb injectors will even deal with a mild cam upgrade.

Now, if you do AFR heads and a 383... different story.
