302 build- speed density?
 

Hi, I'm finishing up a 4x4 conversion on my 88 f150 w/ speed density 302 and I now I want to see about getting a little more power out of this thing.
My plans are pretty simple: Cam and heads. I've chosen a lunati voodoo 4x4 cam advertised as safe for speed density. With an LSA of 112 that should be true. What I'm worried about is the heads, I want to use AFR 165s, will these throw the computer off? I really don't want to swap to mass air right now, and I know a lot of the lightning guys still use speed density. One day I plan to put a blown 351 in this thing, I know I'll probably have to swap then, but for now I was hoping a simple cam and heads swap would be safe. What do y'all think? Also, the truck already has a full exhaust with headers and a built AOD.

The only way the heads will create problems for the stock EFI system is by potentially blowing past the supply limits of the stock injectors and fuel pump, I suggest you get a wideband O2 on it and if it leans out on the topend add more fuel pressure with an adjustable FPR and high flow fuel pump if necessary.

Haha I was hoping to hear from you sir, thank you for the info, glad to hear I can keep the stock SD.

That does assume the cam you selected is truely SD friendly which is less than 210 deg duration at 0.050" lift.

Intake at 50 is 207 and exhaust is 213. It is lunati part number 10350700.
