Is anyone familiar with a company named Price Motorsports? They are/were located in Hope, Indiana. They used to make adaptors to mount various intake manifolds on Ford engines. For example, they had an adaptor to mount a Windsor style intake on a 351W block using 351C heads, either 2V or 4V. Their website www.pricemotorsports.com looks out-of-date. By the way, I've heard all the arguments about how much better aftermarket Windsor heads are compared to Cleveland heads. I'm not building a race car. I am only investigating all the options for a unique, relatively low cost powerplant for a 75 Bronco. I have a 351W block, 400M crank and a set of 2V Cleveland heads.
