Run into a problem in converting to EFI

[bosco]

Well, i have an 87 coupe, with a little 5.0, but right now it has a carb sitting on top of it. Ive been planning this FI swap for a few months now. Luckily i havent bought too many parts yet. heres the problem. I just remembered this morning, that my car is not a roller block, hence it has a different fireing order. Im not sure exactly what year it is but the F.O is 15426378. I wanted to use the a9l computer and have a mass air set-up. What should i do, or need to do? The only thing i can think of is buying a latter model 302, cam, and new pshrods and jsut swapping everything over. I really dont want to go to all this trouble, any suggestions? I know some older cars had converted to EFI, how did they do it??? any help is appreciated.
