So i bought a 351w out of a 1997 e-250. Planning on rebuilding it with http://www.summitracing.com/parts/fem-mhp175-023/overview/
and possibly using http://www.summitracing.com/parts/tfs-5261t561-c03/overview/ for the heads. either the 56 or 66
http://www.summitracing.com/parts/tfs-51403005 for the cam. But i noticed the cam says 10:1 compression. And i cant seem to figure out the compression ratio on either head. Any help would be great.. Ohh and ill be running a pro comp victor jr style EFI intake with edelbrock elbow
