An EFI conversion is definately on my list of things to do with my 1976 302, but it is a bit down the road so I haven't done my homework yet, just some preliminary Googling. However I have come accross a deal I don't think I can pass up, so can you guys tell me if I should get the parts off of this 1992 5.0 HO automatic. I mention automatic because I heard the more desirable swap is for the manual (with the A9L computer) so you don't have the tranny sensor throwing a check engine light since you have no where to plug it into.
I am hesitant because the HO's came with roller cams, and I think mine is a flat tapped, (though I read somewhere that maybe all 5.0's were HO during that erra 88-91) also the HO's have a different firing order (same as the 351) right?
Fuel Rails (maybe)
Fuel Injectors (maybe)
Fuel Injector Harness (maybe)
No Mass Air Flow Meter (Bummer)
1. Does the 5.0 have a flat tapped cam and the HO has a roller cam, among other differences?
2. Can I mate the 5.0 HO distributor with my 302 stock cam, and will that change the firing order?
3. Can I use my stock D50E A3B heads someone said they are better than the 5.0 heads? I do own a set of 5.0 E7TE ie 1987 heads as well, would I have to use those instead?
4. I really don't know what determines the firing order is it the distributor, or is it the distributor/cam combination?
I don't want to get these parts if it means convertng my engine to a roller cam engine, if I have to do that I might as well just drop a complete 5.0 engine in. But then again I have no idea what I am talking about so somebody set me straight, please.
