Injector Size ?

[Jmunk]

I am putting together the following combination looking for suggestions on injector size.

306 bottom end
gt40 heads milled about 20 thou, upgraded dual springs
e cam, I know not the best. I have 1.7rr I may put on it.
edelbrock performer intake
70mm TB/Egr plate

Guy who built the motor said the compression is 10.5:1

Backed by a T5

I am on the fence as to use the 19's or 24lb injectors. Suggestions?

You could probably get away with the stock 19lb ones, but 24lb would leave you room for error.

19s will be fine (i doubt you'll max them out) but 24s give you some room to grow

I would go with the 24's just for breathing room..19's would prob be fine up to 300hp though

The car will have the usual bolt on's, but this will pretty much be the combo I will run. Not looking to add much after I drop the motor in.

I would go with the 24's. I know it was overkill but I had 30's on my last 5.0. The car pulled like a beast and I had alot of room to grow if I needed to. Don't 93 Cobra's even come with 24's?

They do.

I would go 24's myself

I hear a lot of people bash aftermarket MAF's, and alot of others say their fine. Whats the thoughts on the MAF to use with the 24's.

I have a 76mm C&L MAF, never had a problem

24# are more than enough but prolly the ideal size.
