Best engine

Just wondering what the best engine would be for a 1980 F100. It has the 302 in it right now. Looking for the best performance.

How much are you lookin to spend?

Buy a brand new 5.4L V8 straight out of the crate from Ford. Best motor in the business.

I have the 302 in my 93. I had a 1980 with the 300 6. The 6 cylinder is better than the 5L 8. Performance wise the 351 would be best. I wish I had the 300.

i've heard rumors that the gas mileage on the 351 is better than that of the 302 is that true?

That would depend on a lot of things. I'm running a 5.8 with 3.55 gears 4X4 and a trailer package. I'm told the package includes a stall converter Approx. 10 % more stall than regular. I only get 11 MPG. whether empty or full of green firewood stacked to the cab roof. Just put 2 grand in the engine on rebuild to.

well i get about 11 mpg hwy on my 302 4x2 no trailer package (that i know of)

Well putting that in a oldre truck would be a nightmare at best.

I would opt for a 460 0.030" over and 10.5:1 pistons with a cam from a '69 and an Al dual plane intake with a 600 CFM carb for the best overall performance. GREAT Tq, and very respectable power for under $2000.

hows the gas mileage on a beast like that? around 5 mpg? just wondering

Depending on the gears, up to 16 MPG.

damn thats better MPG than my 302, and its bigger. might have to go with that.

i would say run a 390, i have one 13 mpg if you drive it normally. All i have is 10:1 comp comp 941 cam, headers, edelbrock intake and carb, great running motor, but you would have to change you tranny if you had an auto or bellhousing if you have a manual. 351 winsor is a great motor also, if built right you can see the 500 mark on natural asperation.

well you never put boundries on so i'd say an old 429 c.i. should do the trick

The 351 Cleveland is the best.Forget about gas mileage though. Pre 1973 Cleveland that is.
