I hear the Cleveland is nice at higher revs. Nice engines.

... Cleveland's can be just as inexpensive to make power with (Despite common disbeliefs), and that includes retaining the stock heads. Let me know how much power, street manners and usage you're looking for, and I'm more than willing to help.

You already mentioned having the engine gone through, I'd do what DH recommended and have all the gaskets/seals replaced while it is apart, maybe even the oil pump. Then have the engine steam cleaned and painted.bkshaw said:What should I have done while I have the engine pulled out?
Thanks for your advice to this newbie!

I agree with most of what you're saying.69Rcode_Mach1 said:They are both great engines. The cleves have a lot more potential than the windsor with stock heads. If you wanted the car to be a bit more fun you could throw a cam and intake on there and easily hit 400hp. Just a suggestion I would do it. The windsor has its ups too, they also make amazing power and have a huge variety of aftermarket parts. I wouldn't trade one for the other, whichever one I would I have I'd build. Keep in mind that the Windsors are fords most successful and popular engines, there is a reason for that. But either way they are all small blocks, a 351 is a 351 the cleveland just has high flowing heads.

However, Windsor and Cleveland have some marked differences, all designed into the Cleveland to make it superior for a performance application.
1. The Cleveland has smaller diameter mains, improving the high rpm durability of the crank.
2. The Cleveland does not flow coolant through the intake manifold. This is intended to keep the intake cooler, hence more power.
3. The Cleveland has canted valves (sometimes nicknamed semi hemi), which allow for larger valves and more flow.
4. The Cleveland was purposely cast with thin walls to reduce its weight.
And FVIKE I've never heard of Clevelands having cooling problems. And I've spent a lot of time researching them. If the C is making twice the power of a W, it will obviously take a larger radiator to cool it though.![]()
It's not that the cleveland's smaller mains make it stronger, it slows down the surface speed of the crank journals in relation to the bearings. A 3" journal is 9.4248" in circumference, that means it travels that far in one revolution. The Cleveland's smaller 2.75" ( actually 2.749) journal is 8.6394" in circumference, meaning that in one revolution the main journal travelsabout .8" of an inch less per revolution, and when you multiply that times the rpm's that something like a Nascar engine turns, that little, less than an inch distance adds up quickly. ( 8,000 rpms X .7854 = 6283.2", which is about 523 feet) So in effect it's sort of like putting a lot fewer miles on the mains, especially in a 500 mile race.Edbert said:Wait a cotton picking minute here...LOL.
The large (huge actually) mains of the 351W are what make the bottom end so strong, but you are saying the smaller ones on the 351C make it more durable. What gives?
