I'm in the process of buying some used Edelbrock Performer heads at a great price. I already have LT headers, Accufab 70mm TB, and C&L MAF(19#). Should I step up to 24# injectors? None of the items are installed yet and I'm still looking for a used Cobra or GT-40 intake, but I needed to know if I need to be rounding up some 24# injectors and a 24# sampling tube?

Thanks,
RT

Your stock injectors should be fine. I don't see a cam listed anywhere in your setup. At most,(but I doubt it) you may need an adjustable fuel regulator. The folks really familiar with MAF can confirm or deny that, but I don't see anything in your setup that would suggest that the 19lbers couldn't handle it.

IMHO you best off saving your $$ cause your probably get best results upgrading your MAF-injectors-fuel pump, then you can be safe and provide enough fuel without maxing out the system.

I have a 190 fuel pump and adjustable regulator as well....sorry I forgot about those. I do need to pic a cam though. Thought about going with a TF stage 1.

With heads, I would definitely say go with the 24 lb. injectors. 300 fwhp is usually the limit for the stock injectors, and you should be above that.

RTGreen,

My 90GT 306 NA has performer heads, intake, 70mm tb, 73mm C&L, 24# injectors, Crane 2030 cam, 8.92:1 compression...way more stuff. The bottom line is I hit 85% injector duty cycle so 19# injectors wouldn't work for me.

Good Luck, Don
