I'm about to swap out the 305 from my Iroc to a 350 out of a 90 formula. I still have both ECM's but only the harness for my 305 with it's MAF system, which wouldn't work with the formula's speed density. what should i do?

 

I coulda sworn for a 305 to a 350 swap, all you had to do was get the correct chip for the computer, and put larger injectors in.

Unless, that is, you -want- to switch over to speed density!

Oh and I guess you know this but you'd need a 350 MAF chip, you couldn't use the 350 SD chip from the extra computer you have.

 

that's awesome. so all i have to do is pick up an 89 chip and i'll be set? and to think i was about start chopping up my harness for the SD!
