im looking to swap my engine, where have you guys gotten your 302s? i need one thats carbed formy 79 2wd man.

 

Crate, remanned, or rebuilding yourself?

 

I got the engine that will be going in my truck from a '90 Mustang GT although, I plan to keep it fuel injected.

You can put a carburetor on an engine that has fuel injection. The main advantage to using an engine from a 5.0L Mustang from 1985 through 1995 is that they will have a roller cam and forged pistons through 1992. --'93-'95 5.0L engines have hypereutectic pistons. (1985 first year for roller cam 5.0L engine, also last year for carburetion in a Mustang).

1996-2001 5.0L Explorers are also very good engines. '96-'97.5 had GT40 heads. '97.5-'01 had GT40P cylinder heads.

Any 302 or 5.0L engine from '81-2001 will not have a threaded hole on the left rear side of the block for a mechanical clutch bell crank pivot but, an adapter brackets is available if you have a manual transmission w/mechanical clutch. '81-later will also have one-piece rear main seal instead of two-piece like previous years.

'86-'95 Mustang will have TFI distributors. '96-'01 Explorers have EDIS-8 (they don't even have a distributor).

All serpentine accessory drive 5.0L engines will have reverse flow water pumps.

 

what is the mechanical clutch bell crank pivot? are you refering to the "z bar"?

where can i find the adapter bracket?

are you saying that i can pull basically any 302 engine that is fuel injected and slap a carburator on it?

 

There is a little more to do than slapping a carb on it. If it is a roller cam engine, you need a steel distributer gear or else it'll quickly wear itself out. You can use a distributed from a 1985 mustang with a 5.0 and a four barrel. It was the only year for a roller cam and a duraspark ignition. If you are using an aftermarket ignition you could use a 1985 and up 5.0 efi mustang distributor since most are compatible. The firing order is also different on the 5.0 compared to the older 302.

The timing cover won't include a place to mount the fuel pump. There won't be an eccentric on the cam either. I bolted the stock timing cover, eccentric, water pump and accessories from my 1976 when I installed a 1999 Explorer 5.0 in my truck.

The Explorer 5.0 with Gt40p heads have relocated plugs so stock manifolds won't work. There are headers that do fit. Mustang engines shouldn't have this problem.

The oil filter adapter, pressure sensor, and other minor things may and probably will be different. It should all swap over.

Also, 302/5.0's after 1981 will have a different balance than earlier engines. You can't mix flexplate/flywheels and balancers between the early and late engines.

Look at the tenth item down on the above link. I was going to buy one for my swap but it's an easy bracket to make if you can measure and cut metal.

Basically, if you want an easy and usually cheaper swap, look for a pre 1979 truck engine. It'll be mostly a direct swap. Less stuff to buy and swap to make it work since you can use most of the parts off your engine. The later engines are nice since a junkyard engine will usually have fewer miles, have one piece rear mains, and are built with better tolerances. But, you will need to collect more parts to make it work.

 

Yes to the first question, "Z-bar," "bell crank," same thing.

Yes to the second question, CJ Pony Parts. CPC Mustang Equalizer Bar Bracket Engine Side, 5.0L

Yes to the 3rd question. Swap out the EFI upper/lower intake for a carbureted intake and a carburetor.

 

All good info above.
In addition, 302 EFIs were used in 86-91 CVics and Grand Marquis, 85-90 or 91 Town Cars.
Not as much power as a Mustang though.

 

I have a 79 f150 with 302 in it. Its a parts truck and the engine will need a rebuild. It pulled its self on the trailer when I bought it.

 

Yep. Those are non-H.O. 5.0L engines. They will have the old 289/302 firing order of 1-5-4-2-6-3-7-8.
H.O. engines will have the improved firing order of 1-3-7-2-6-5-4, which is the same firing order as the 351W/5.8L engines.

There's also the issue of Speed Density contolled engines vs. Mass Air controlled and sequential injector firing vs. batch (or bank) fire.

Mass Air and sequential injector firing is much better than Speed Density or batch fire. --especially if gaining performance from the engine is the object.

--but, this is IF a person is keeping the engine with EFI.
