What Size Injectors for AFR165?

[Kurt2002]

Will my 19lb work with AFR165 head, Edelbrock preformer intake and stock cam?

I also have 30lb I cound install. Which would be better?

19# will work upto about 300rwhp, which you will be below with stock cam.

go with 30# and get a differenet cam to utilize the potential of AFR 165's...stock cam is a slap in the face with those heads...

yeah it doesnt really go by what heads/intake you have, more on what your combo will be producing. Some people go by the chart, i personally think the chart stretches the use of each injector too far. (o yeah, theres a chart thing floating around on a bunch of sites matching the HP to the injector, i know the Pro-M site has it) So my theory is use the chart to figure out what injector u need and then go one size larger in most cases. too big is bad but one step up wont hurt. y work a smaller injector alot harder when u can use a somewhat larger one at moderate duty.

quick and easy answer: H/C/I 302/306 liek around 300 HP go with 24's. my 331 is gonna have 30s
