Clevor type, big hp

It consists of a Windsor block outfitted with Cleveland cylinder heads. It’s not limited to a particular displacement and can be built on a 302 or 351W platform. Unlike the old days, many off-the-shelf components are available for the Clevor. The 427 will require an aftermarket block with a 4.125″ bore and a 4.00″ stroke crank.
