Default Mass air conversion (need help)

I'm getting ready to do a conversion on my 87' gt, i have a c3w computer out of a 93' and complete wiring harness also out of that same vehicle, i did some research and the computer is for an auto but the car it was in was 5spd and my car is a 5spd so what i want to know is will this work or do i need a different computer. And if it will work do i just plug everything in or do i still have to splice and reroute wires, and will a e303 cam work with stock e7 heads without any work done other than valve spring change? so if someone can please let me know i've never done this but i'm mech. inclined so a little help goes a long way. i'm tired of looking at these parts not on my vehicle, so if you can help i would really, really, be thankful.

as far as i know the e303 will work just add some stiffer springs and remember to check the piston to valve clearance just to be on the safe side.

your computer that you have will work...i used the a9p's a9l's,and cali computer and never had problems no oddball codes or anything.

if you have a complete conversion computer/harness and meter from a donor efi car..it's just a plug/play conversion
