The 302 & 351 will change out with the 300, but you will need stuff like the motor mount pedestals, radiator, wiring harnesses, exhaust, and the flexplate or flywheel for the 302 or the 351 Windsor, whichever you decide to use. You will not have to change the bell housing on the transmission because the 300 uses the small block bolt pattern.

If there's anything I missed, I'm sure somebody else will jump in & come to my aid.



1988 F-150, SWB, 5.0 EFI (formerly 4.9 EFI), M5OD 5 speed, 3.08 gears, Summit shorty truck headers, Custom built Flowmaster exhaust system. Force 4 LP6000 lightbar, Federal signal PA-300 100 watt siren, Icom IC-V100 50 watt mobile radio.
=======================================
1965 F-100 (just purchased 1/18/01), SWB, 390, C-6 auto. Dual exhaust, Not much else to do to it.

Can see both below.

Cliff: Why not go with another 300 and preserve history? No doubt the easiest swap for compatability. If it is more power you need, I have heard awsome power comes from Clifford performance with a CAM, header, and a 4BBL carb. Check out their website. Everone has a V-8, but High Output 6's are too few and far between. Sounds like you have a good canidate for the upgrade. (pre-computer controlled easy to upgrade).

Long live the I6!
Chris

keep the six, they sound great with a good exhaust system and you can't beat the tourque.

Keep the six. I have an 88 with a few mods. I can pull with my buddies stock 5.0. Just go with a good intake and exhaust. One other thing is to upgrade to a good ignition. That seems to be the one thing that most people forget. Keep in mind the brag factor when someone asks "Damn,what ya got in that thing" The look on their face after being thumped by a six is priceless.
Good luck,
BLACK
