Clevland vs Windsor!

Unit 5302 · 02-27-2001, 07:12 PM

The 351C uses the same bore and stroke as the 351W. The similarities almost end with that exclusive one.

The 351C uses canted valves allowing for larger valves to be placed on a limited bore. They came with valving up to 2.19" intake 1.74" exhaust.

The 351W uses much smaller valves, the largest I've seen is 2.02" intake 1.60" exhaust.

The Cleveland has a different 4 bolt main block, different heads, different everything really.

Stock vs. stock, the Cleveland will whip the Windsor, no problems. Tuned, the Cleveland will more than likely kick the modified Windsors butt. You cannot get aftermarket Windsor heads to outflow the stock Cleveland 4v heads. We're talking intake flow rates of 285cfm stock. Aftermarket aluminum heads will be more manageable on the Windsor though.

You've got a couple options to look at.

The Windsor will generate significantly higher levels of low end torque stock/light modded, they are easy to run EFI on, they have a huge aftermarket availible, and they are lighter.

The Cleveland comes ready to rock from the factory with tons of power potential in 4V form, it's got oiling problems (needs passage restrictors put in), it's expensive to mod, aftermarket parts supplies are low, they are difficult to convert to EFI, they are heavier, and the later 70's blocks had come cracking problems.

All out power: Cleveland
Budget minded: Windsor
Fuel Injection: Windsor
Reliability: Windsor (everyday driver)
Reliability: Cleveland (over 600hp)
Cool Factor: Cleveland
Aftermarket: Windsor
Chassis Fitment: Windsor

They both have their drawbacks and benefits.
