Is 19 pound injectors a lil to small for a n/a 331?

[wicked90lx]

about to finish my 331. more then likely goin to be driven a lot almost a DD. Comp ratio should be around 10.5:1. AFR 185s 58cc with a holly systamax intake, holly 255 in-tank pump. My question is what would best suit me 19 or 24 pound injectors?

If it were me I would get 30's.

Agreed. My setup with 24lb'rs according to the mathematics are pretty high in the duty cycle. I'd say a n/a 331 with 185 heads would def need 30lb'rs.

Do not use your stock 19lb injectors on a built 331 with a 255 fuel pump. Throw them out and get some 30's. I have 24lb on my stock bottom end with a 190 fuel pump. I'd go 30 for sure on a 331.

Nothing stock should be left on a built 331....except the block and the accessory brackets.
