What’s my engine?

Rookie question - can someone tell visually if the engine in my old F-100 is 351 Cleveland (due to the 8 bolt valve covers)? Or is the engine something else? Thanks in advance

The Cleveland was never factory installed in a truck but at this age it's possible to find anything under the hood. The 351c and 351/400M are very similar and use some of the same parts but the 351c block is physically smaller and it has a removable timing cover like the windsors whereas it is cast into the block on the M.

If you look at his name (Aussie dave) and the righthand drive it should be a give away. By the 4 bottom bolts on the valve cover it at a C or M engine

Yeah I thought he might be down under, his post is also in the wrong forum but that is something for the mods to sort out.

Thanks for the speedy replies. Appreciate your knowledge and experience.

The truck seems to have bits from the seventh and eighth generations, so it’s a somewhat hard to assign a forum.

I was guessing a 351C, but wasn’t sure if it was a 302C that I gather was unique to Australia and if there was a visual trick I was missing. My mate suggested I pull a plug and put the dipstick/a straw in the bore with the piston on TDC. Mark the dipstick.Turn the engine over by hand. If 3 inches?, it’s 302. If 3.5 inches?, it’s 351.

Cheers again

Is it running on LP?

Looking at the exhaust sez it's something 335 series headed.
