351 Cleveland pros and cons
what are pros and cons of the cleveland motor?
i know its better because it has the smaller mains so it will rev faster? am i correct on that?
i also beleive that oiling is a problem, but a restrictor kit will eliminate that? right?
anything else, strength of the blocks etc etc?

The only real con in my opinion is the slightly higher price of parts. Used to be parts were hard to find, but even that isn't really a problem anymore. Aftermarket cylinder heads and intakes are now readily available, as are all bottom end components. The block is the only thing that you need to find.

Small mains means less frictional drag, shorter deck height means shorter pushrods and better valvetrain stability at high rpm. The heads are both pro and con. The design favors large flow, but the con is factory head castings aren't the best for what you may want to do. They favor higher rpm. They're a sturdy engine though. I wouldn't build one with stock heads though, but I suppose that's just me.

well the aussie heads are from what ive heard the best for street applications cause of the 2v runners and the closed chambers, i also heard that they flow fairly well. and i dont have the money for aftermarket heads :P

I trap over 118 with a 11.5 1/4 with my stock heads on my 410c and can drive it anywhere 
If you are not spinning over 6500-7000k repeatedly then you have no oil concern with the 351c.
Please note you also have to run solid lifters to run restrictors so if are picking a hydro cam then you can not use the oil restrictors anyway.

On the basis of a 351 Cleveland vs a 351 Windsor, the Cleveland is heavier and cost a little more to build. The Cleveland blocks and well-known for their core-shift issues that make boring them out a possible problem. Clevelands are very strong engines and cool to have, but the Windsor is easier to deal with as far as transmissions, motor mounts, aftermarket parts, and overall cost.
