Motor swap question
Hey all.
i got an old 85 302 HO sitting in my shop that is about to go for a rebuild. I wouldn't mind building it up to suit my 94 f150 that has a tired old 5.0 in it already. Will this swap be pretty straight forward? Anything I should know?
Thanks in advance!

It is straight forward, just use all of your efi top end on the old long block and match firing order as said above.
If you have the money, get a 347 rotating assembly. Building a 302 has yielded disappointment many times.

So the blocks are essentially the same. i would like to get a slightly more aggressive cam for it, as long as it matches the HO block instead of the f150 block it should be good?
I will look into stroker kits as well but the budget for this isn't huge.
Thanks both of you!

I guess the engine was out of a Mustang or maybe a Lincoln? The blocks should be exactly the same externally. The cam choice depends on whether the block is already set up for a roller or flat tappet cam. You can put a roller cam in a flat tappet block but it is more expensive.

85 was the first year for the roller cam in the Mustangs. The cam gear on your truck distributor is not compatible with a roller cam.

All '92+ 5.0 truck motors got roller cams so use the distributor from your truck.
All "94+ truck motors used the HO firing order.
This HO motor already has more cam than your truck motor did.
