Engine swap
 

I have a 1985 F150 that has the 300 straight 6 in it. I want to swap it with a v8. A friend gave me a 2002 5.4 L and from what I've read I'd have to completely redo the whole power train to make that work. I was just wondering if this is true.

That swap is more work and expense than it's worth. Yes, you would need a different tranny and a whole bunch of custom electronics and wiring. A 302 or 351W is a much easier swap.

That's what I was thinking. Just wanted to double check before I sold the 5.4. I'll be going with a 351. Thanks for the help

460
 

I have a 4 speed in the truck right now and was maybe wanting to go with a 460. I don't drive the truck very far so gas mileage isn't an issue. Just want power. I was wondering if the 460 would fit easily in the truck or would it take a lot of modifications

300 to 351W swap
 

I have a 1985 f150 with a 300 and 4 speed manual transmission I want to swap the motor with a 351w but wanted to know if the 351 would fit my transmission or if I'd need a new transmission or bell housing. Just want to know what I'd be getting into before I go that route. Any help is appreciated. Thank you

That six you want to take out is one of the best engines Ford ever sold.

It is a good engine but underpowered for what I need it for. Therefore I need a V8

The 300 uses the Windsor bellhousing pattern, so the trans will fit. You will have to find a manual transmission flywheel for a 351 if it came out of an automatic.
