302 motor?
i recently installed a 302 from a 77 f150 into my 86 f150 and today i noticed that the oil pan of the 77 f150 had a humpin the center and 2 seperate drain plugs one in the front and one is the back is this a common set up for a 77 f150 302

Ford went to that dbl hump when they came out with the new frame in 1979. It would be nice if it were an 86-91 EFI converted to carb, it had a roller cam. 79-81 maybe 82 used the VV carb, then went to throttle body injection until 86, Then EFI.

Pull the intake and look for the "dog bones" that hold the lifters in place. Should look like this....

then you will know if it's roller or flat tappet. I'm fairly sure not all 86-91 302's were roller. I could be wrong tho. Been awhile since I looked into it. If it was a HO motor it was a roller for the 302's then.

I knew that the truck motors had the ability to become rollers. I just thought that in the 80's the HO engiens got the roller lifters. Then the non HO were flat tappet. Either way it is what it is. Good luck om the engien transplant. I hope it goes well.

It could be stock. When Ford went to EFI in 86 (cars) the used roller lifters. 85 302 I had did not. 86, and a couple of 89's I re-did had rollers. As evident by above pics, the push rods have to be shorter for the roller engine. For some reason - probably money- for didn't use roller rockers.

As far as mustang motors go: 86-92 were HO firing order, roller cams, and forged internals. In '93 they switchted to Hyperutectic pistons.
and if you are converting an EFI motor to DSII / carb you can use an '85 Mustang distributor ($50 NEW, entire distributor) but it has to be from / for a manual trans car (Auto trans had EFI, also Calif Emissions cars had EFI). '85 was the ONLY year that had a CArb, the correct gear for the Roller cam, vacuum advance, & the DSII ign hookups.
