can you define asshat?

Umm...simple You....

ummmm... ok? Anyone else have any USEFUL, PRACTICAL, and ACCURATE input?

I'd like to go EFI because of throttle response and ease of configuration. The last time it ran, it had a Holley 650 double pumper. It screamed in its own right... ate up plenty of Camaro's, Corvettes, and even a few other ponies (most of those had no clue how to drive!).

I just like the idea of being able to set all of the engine configurations through a computer rather than twisting the distributor and turning the fee screws on the carb, guessing that I'm even getting it close to where it should be.

Hey chord,

Not sure but if this EFI system is programmable it would seem to suit your increased displacement needs, particularly if you can change the injectors themselves. Modding the intake system might be needed to increase volume as well but should be doable.

Good luck with the project.

The EFI I'm looking into getting would be from an 89-93 Mustang GT. If I've read everything correctly the intake, heads, cams, headers, and accessories should bolt right on to the 351 from the 302. I have no experience with EFI. I'm going to see if I can find out which ECU's were used on the 351's and see if any cross reference with the 302 ECU's.

Ideally, I'd like to find the GT-40 heads and intakes from an Explorer and take a complete EFI from a late model Fox Mustang. On paper, it looks good and I haven't seen anything that says it won't work.

I'll build the block up with forged internals and prep it for turbochargers. After that, I'll build up the suspension and chassis and tackle the interior after that. Lastly, I'll see about scavenging some turbos from a turbo t-bird or cougar and piece together a twin turbo setup. My goal is to have an aggressive daily driver that does well at the track (low-mid 12's would be nice!).

EDIT: Didn't take a whole lot of digging. Read on:
So the answer to my original question, it seems, is that the 5.0 ECU will handle the 351W just fine. It simply measures air and fuel needs and delivers.

Unless someone has other information, I'm going to consider this solved.

I don't know much about doing a carb to efi swap but you won't be able to use a 302 intake manifold on a 351. The 351's intake is wider then the 302s but everything else should swap over.

I would just stay carb..alot less headache.....and cheaper....

chord509

Yeah, you raise a valid point. However, it would be a lot less of a headache and cheaper to just buy a used Mustang. That wouldn't put my Mustang back on the road the way I really want to. I'm not looking for the easy or the cheap way out. In fact, I've assisted in rebuilding an engine once and some of the work I'm talking about doing I've only seen on the internet. So, I'm not fooling myself into thinking that it's going to be quick or easy. It will probably take me several years to do it right. Money pit? maybe... probably, but if it works I'll have a car that I can be proud of and enjoy.

[ul][*] Full resto of my 1985 GT w/T-tops[*] Rebuilt (possibly stroked) 351W with forged internals[*] Complete EFI swap[*] Twin turbo setup[*] Full chassis and suspension upgrade for street/strip application[*] Rear disc brake conversion[*] To do all of this using as many junkyard pieces as possible without compromising safety
