351c f100

Hey guys im new to this forum and i have a question. I just picked up a 76 f100 with a 351 Cleavland in it. It has no posi, idles at 600, the motor is almost brand new, and runs strong, but the truck cant lay rubber what so ever, does anyone know what my problem might be? And it cant accelerate at all. Thank You!

problem is i think you'll find it's a 351M not a cleveland.

but as to acceleration problems, be more specific. you pound the peddle to the rug & she falls on her face & maybe dies or?

accelerator pump would be my first guess.

I side with one of the previous replies, I think you have a 351m. I didn't think they put a Cleveland series in the F100's. According to what I've read, about 39% of the F100 series had 5.9L 360's, didn't they?

Anywho, I had a '75 F100 w/ a 351c (from a '77 Shelby we had that got clipped in the back end), a posi rear, & manual tranny. It would boil the tires in 1st, bark them hard in 2nd, and felt like it would break loose in 3rd. I loved that truck & have been trying track it down for the last 10 years...

You may want to check your rear end ratio as well, maybe geared too high...

yeah i had a cleveland in a 70 torino gt & she was a beast. Rolling start you could stomp the peddle & she'd rip the tires loose.

351M & C are 2 completely different critters.
