78 High Boy Engine Swap

Hey Guys!

I was hoping someone could help with an engine swap scenario and let me know if it's possible...

I have a 1978 High Boy and I was wanting to put a 302 engine out of a 94 f150 into in (got a good deal on a rebuilt motor). Will this bolt up to my 4 speed 4x4 tranny (has granny if that matters)?

I know I will need to swap to an electric fuel pump and swap the intake to a carb version, but I'm mainly concerned if it will bolt up.

No you don't.

High Boys are Regular or Crew Cab: 1967/76 F250 4WD, 1977 F250 4WD before serial number Y20,001. High Boys have an in-cab fuel tank and a divorced Transfer Case.

1977 F250 4WD's assembled from serial number Y20,001, 1978/79 F250 4WD's are not High Boys. Have a married Transfer Case, no in-cab fuel tank.

Excepting 1969/77 Bronco, 302 not available with 4WD until 1980.

If you're wanting to throw a carb setup on the '94 engine, you will also need a Duraspark distributor. And if the '94 engine is a roller cam engine, you will need a steel driven gear for your distributor. I'd rather see you make the Ford ignition work, rather than throw a bulky HEI on it.
