how much power are you aiming for? custom cam and heads don't tell the whole story but I'd say a 36# injector should fit the bill for pretty much what you're planning

Id say 7000 max with the stock pcm and make the most of the power band. Just make sure you have arp bolts everywhere that counts and a good machinist.

well the stock is actually a "dampner" unless you're planning on a pretty serious build stock should be alright

30# svo's worked for my 12:1 383 making a little under 400rwhp. for a decent brand I'd say trying to find pretty much any Ford/SVO injector as they are fairly high quality, not expensive, and pretty common especially 39# (03-04 Cobra) and 42# (Lightning)

Racetronix Delphi 37lb injectors ! But I think if 400 is your goal a set of LE2s with that cam would be close
