just bought me a new truck

351 cleveland
dana 60s
granny gear 3 speed

and my other baby 03 fx4

 

I believe you mean 351 Modified. The Cleveland hasn't been built since 1970, and it is a small block engine. And Ford didn't put small block v8 engines into 4wd trucks in the 70s (if it is a 4wd) Although someone could have installed a Cleveland.

 

the 351 cleveland was a big block the small block is the 351 windsor the cleveland wasnt even introduced till 1969

 

really.....?

 

Both of you are confusing me..... Ford put small blocks in there trucks in the 70's, with 4wd, I know the 78-79's you could get a 351 or a 400(both small blocks)....I think anyway

 

the 351 cleveland was a small block with big block heads. but if you were to race then you'd have to run with the big blocks. and it was produced from 69-74.

 

well all i know is the vin on motor say cleveland

 

if it's a clevland someone probably put it in there. 77 's had 351 modified's and 400 blocks, they were totaly different from clevlands or windser's.

 

i guess thats where its nice having a 460. they only came in one size

 

yea found out someone put it in there didnt think to check the numbers on the truck and motor was a 351m

 

I told you so...Just kidding. BTW, the Cleveland IS a small block. It will directly bolt in place of 260, 289 (as long as it is a 6 bolt bellhousing), 302 and 351W. The engine mounts and bellhousing bolt patterns are the same. Only difference is accessory mounting and exhaust. The 351M is essentially a 400 block with 351W crank and Cleveland style heads which make this a big block engine. It shares the bellhousing pattern with the 400 and 460 engines. The 460 requires different engine mounts.

 

the clevland is not a small block the windser is, the clevland is the same family as the 351m and 400 block. i believe its the 335 series, they are between the small block and the big block.

 

Then why does it have a small block bellhousing? The 351m and 400 use the same cylinder head design. Small block Fords have one bellhousing, the FE Fords have a specific bellhousing, and the big block Fords (ie 429,460,351M,400) have another specific bellhousing. The Cleveland bolts up to the small block bellhousings. You can't bolt a Cleveland to a big block bellhousing period. I understand your reasoning, but the Cleveland is a small block! Heck, there are still die hard Chevy guys out there that would swear that the only 302 motor belongs to Ford.

BTW, your earlier post indicated that the Cleveland was "totally different" from the 351M and 400 engines. You can't have your cake and eat it too.

The 335 series engines designate Ford small blocks of which include the 351C. Google it!

 

the 351c, 351m, and 400 are from the same family, the term "totally different" comes from what you described, the 351c retains the small block bellhousing. the 351m and 400 have taller blocks. the 351 clevland will not fit in the same cars as the windser due to the larger top end. the winder's water inlet is thru the intake manifold and the 351c, 351m and 400 is thru the block. the heads were used between the 302 351w and the 351c to achieve the boss motor but they are not a dirrect bolt on. i believe the cranks have different journal sizes. also bigbronc i got your message im just not sure how the messageing works im not that great with these computers.

 

I've got a thousand bucks that says you're wrong. The 351c will directly bolt into where a 302 came out of (I know, because I did it in a 70 Mustang, thank you). It has a 4 inch bore and 3.5 inch stroke, just as does windsor. True, the cleveland has a different block, BUT it WILL replace a 289, 302, or 351W. Like I said, just change the accessory mounts and exhaust and voila. The 351m and 400 are DIFFERENT blocks because they have big block bellhousings. The 335 series is the smallblock series that includes the 289, 302, 351W AND 351C. End of discussion.

As far as the Cleveland not "fitting in the same cars as the windsor", howcome it came in the Cougars, and Mustangs from 1969-1974? Were the engine bays different from car to car? Ever heard of a 351 Boss? Guess what, it wasn't a Windsor engine.

And the heads will bolt on, but you have to alter the water passages. Pick up any Ford Motorsports catalog and it will have a section showing you how to do that to make a Cleveland head mate to a 302 block.

What's wrong, don't you have Google on your computer? I know this from 20 plus years of working on Ford engines.
