The W and C blocks both have their drawbacks. All in all the W block is probably the better unit. However, that being said, by putting C heads on a W block you now have what's called a "Clevor". The problem with that is that neither W nor C intakes will fit, and neither will any standard C or W header. The choices on Clevor intakes is very slim, and headers, especially Cobra units with sidepipes, will need to be custom made, which is VERY expensive. The C block can have all the oiling issues solved for MUCH less than the cost of all the custom parts needed to put a Clevor into a Cobra. In the end both the Clevor and the Cleveland have warts, although the C warts can be solved cheaply and easily. Also, the new C block coming out has none of the oiling issues of the original - they're fixed. By the way, be aware that the oiling "issues" only come into play on engines spending lots of time over 7000 RPM. The W, while an easier build with more common parts, will take considerably more money to match the power output of a C headed engine. It's your $, where and how do you want to spend it?

Go to MME Racing's site. For $6K Mark will build you a 408" stroker Cleveland with 560 HP, and for an extra grand they will put the latest in C aluminum heads on it, which will push you significantly past the 600HP mark, for about $7K. There is no W head on Earth that can flow what a stock state of the art C head can flow - that's the reason NASCAR uses C heads. This power output is available on pump gas, with a flat torque curve, and max power and torque down well below 6800 RPM. The old story of needing to spin a C to ridiculous revs is a 1970's problem that is LONG gone - it's been relegated to the dustbin of mythology. It was once true, and just simply isn't true anymore. Can a Windsor do all that for that price? I don't know for sure, but I do know that I've certainly never seen it for anywhere near that price.

What's a Rousch 550 HP engine going for these days? I believe it's well north of 13K now, isn't it? That's a HELL of a lot of money for what, less power and a warranty? For that price you can build the above C, blow it up and buy another, and probably STILL be ahead of the game. Don't get me wrong, the Rousch is a beautiful engine, but DAMN that's a ton of money to spend to get less power.

In the end, there's no wrong answers, only a choice of how much power you want and what you're willing to spend to get it.
