viking said it all. However the aftermarket has embraced the 351 Windsor. I like the windsor family of small blocks because parts are easy to get and 450 to 550 fwhp is the norm with stroked and non stroked motors. I'm not putting the Clevland down I've seen a lot of fast ones but I've never owned one but I've always heard of the oiling problem. The windsor use to have breathing issues because of the small heads but the aftermarket AFR, Trickfow, Canfeild, World, Brodix, and many other have make the Windsor into an unbelievable power per dollar value.
