300, 302, 351... 460... ok, i don't think they put 460's in f150's, but they did put them in super duty's and broncos.

 

edit: also a 400. and in an f100, a 255 v8 and a 232 6.

 

and a 420 diesel for the f150, but... wink.gif

302 trucks have a much taller intake, and the lower intake ports are very large at the top, but neck down to a size that you can cover the port with your thumb at the head mounting flange, I believe the heads are the same as 5.0 HO (mustang and LSC lincoln). If motor is port fuel injection, it has a roller cam. If it is CFI(looks like carb, but has 2 injectors)it is flat tappet, I once did some work on a 85 GT automatic, it had CFI, and a flat tappet cam, in 85 only 5spd, HO 5.0 4 barrel carb, had roller cam,other fords have intakes like HO motor, but heads, pistons(no valve reliefs,i.e. very small cam),cam, and intake has smaller ports. These motors have good short blocks if you are going to rebuild it and replace the pistons and cam, the roller lifters can be reused, just clean them real good. Also the above mentioned truck lower intake is used in race applications, but only after spending much time with a grinder, and a welder.hope this helps

and... that's batch fire injection, probably - okay almost certainly - MAP based. Improvements to airflow will cause the egine to "hunt" at idle and run poorly but some have had success modifying Mustang MAP motors just fine. The fact that it's got a poorer EFI setup would bother me if I were going to keep that. Not sure if th emotor has roller bosses for the cam if it's flat tappet either but I'm told, at least on the 351Ws, that so long as the cam isn't really big you can still run a roller just fine and not expose the oil holes. Roller blocks have taller lifter bores apparently...

 

Oh - if it's a V8 then it will probably be a 302.

Do any of you guys know about Thunderbirds. I had bought a 1990 302HO from a mustang, but it was shot. I got a really good offer ona T-bird, but I don't know if it's equipped with mass air. The intake says EFI, but it looks the exact same as the HO intake. Do they look that similar. Also is the bottom end as strong as a mustang? icon_confused.gif

If it is a MAF system it will be inbetween the air box and the intake. The clean air tube will go in one side and the intake tube will come out the other side. It has a 4 pin plug on it. If the entire intake, meaning the air box and such, look exactly the same then it is probably a MAF. If I knew what year T-Bird I could tell you exactly what kinda of system it is. As for the bottom end power, I have no idea.

 

And i agree with BLKMGK and Jamie T, the MAF system is alot better then the MAP system.

It is a 1988 T-bird. I am pretty sure that until 97 they all had the speed density. Also do you knon if the heads were different on the HO motors compared to a regular 302

Hmm, cam will be tamer, lower compression I'll bet (?), but mostly like th eMustang. It will almost certainly be MAP and NOT MAF. Mustangs didn't get MAF until 89 except in California so I doubt the 'bird will have it. Don't sweat that too much as converting it over could probably be done fairly easily like it can be on the Mustangs.

 

Can you find no motors from Mustangs? As many of them as have been made and as many punks are wrapping them in trees I'm shocked! icon_eek.gif Look around, if you're lucky some punk will bash one that's already been built up...
