    Default 302 Ford question

    Hey all,

    A co-worker is telling me has a late 80's 302 w/ TPI injection (that motor is hurt). He acquired an 85' 302 with TB injection.
    Can he put the late 80's TPI manifold on the 85 TB engine?
    Are the heads, cam, compatible?

    Thanks in advance. I have not seen either motor, just going by what he is telling me.

    You called a late model, injected SBF a 302. Blasphemy!!!! Yes it will fit. The problem may be in the cam. The 85 TBI motor was a wimp, and was the standard engine on automatic cars. 85 stick cars were 4 bbls. If the TPI manifold is a 88 or newer california car, or a 91(?) later 50 state motor, it has a mass air sensor and will propably work just fine. If it a 88 and earlier motor, it is a speed density ECU, and may run less than stellar. Now if he moves the cam from the TPI motor over as well, it should be all good.

    No matter, the thing will make less HP than the TPI motor. The 85 TBI, and all 86 TPI motors had shit heads, and pistons with no eyebrows, and "down the hole". It is by far the worse "5.0" of them all.

    Very good info GN, thanks!

    Next question. If He moves the cam over as well, which timing set is required??

    Are we talking 302 Ford? Because they never had "TPI".

    Or, are we talking a 305 Chevy with TPI???

    Hopefully it won't be an issue, but keep in mind...
    firing order for H.O. and non-H.O. motors (cams) were specific for each and differ from one another. With the years you mention I am not sure if that would effect you or not.


    (I will admit learning this the hard way years ago)

    They are both "HO". Thats why I gave him grief for calling them 302s in the opening post Both the 85 TBI and the later TPI have the same firing order.

    Thanks Guys!!

    This is no performance deal at all. He got the early motor for cheap or free and is just trying to get the vehicle running again.
    He wants to swap the port injection to the early motor so all his connections are the same.
    Looks like that is what he will do, as well as the cam and a new timing set.

    Thanks again!
