what is the difference between a 351 windsor and a 351 clevland and why do they say that the 351 clevland is better

351C


351W


351C 4bbl Heads


351C 2bbl Heads


351W Heads


a C is almost the same as a 351M/400 motor. those two are very hard to tell apart. the C's (and the M's) are pretty much a big block in size and weight, and have oiling issues in stock form.

the W's are sturdy and well designed from the factory, but lack the power potential of the C's because of the head design. this is why alot of people play with "clevor" motors, which are W blocks with C heads.

here is an example of a "clevor"

One of the biggest diff. is in the size of the stock head porting

351C intake ports:

yup, and pictures dont do the 4bbl heads justice because them ports are HUGE

+1 lets just put it this way, i was embaressed to set my Big Block 440 mopar heads next to my dads Small Block 351C heads. They just make everything else look so wimpy.

the only thing that comes close are the 429/460/BOSS 429 heads



and the rectangle port big block chevy heads (here is a gasket comparison of normal BBC heads and the rectangle port heads)

so basically clevland is just a little more powerful thats all

ok..... go back and really LOOK at the first two pictures. notice the heads are completely different. notice the blocks are completely different. notice that aside from main journal and head bolt spacing NOTHING is the same between the two engine families.

Yep....just a little, but enough to have them banned from competing in some "circles"......
