you might seriously consider using some iron Windsor Sr. heads and the 392 stroker, you'll still save money over the 408 stroker kit even with the heads and they will out flow stock or mildly ported 69 351w castings.
What is the difference between a 393 and a 392 stroker crank, I confused myself here. I looked at this crank, http://cgi.ebay.com/ebaymotors/351w...016QQitemZ260129339504QQrdZ1QQsspagenameZWDVW in the 393 and I read it would work well with the existing rods and the 302 pistons, is this a good deal for the crank? Thanks again and I apologize for my lack of knowledge in this area.
