Basically took a new Ford Racing 450hp 347 and dropped at my engine builders shop. Complete blue print, about 5 hrs short turn radius work on heads, port match and cleanup. True decks to give comp a slight bump. Reassembled with all original parts with exception of Melling Select pump, MLS head gaskets and Aviaid GT40 pan. Very mild tune running right at 12a/f with 35 degrees timing all in by 3200 rpms. Water temp 178,
oil temp 190. No doubt we could have gotten to 500hp if we leaned on it a little more.
5000 trouble free and fun miles since build completed in July 2010.
Currently building 363ci using basically same parts with exception of h-beam rods, internal balance, higher quality pistons, 11:1 cr and mid level solid roller. Hoping for 550-575hp with a usable RPM range up to 7200. Considering new Edelbrock XT FI for this engine.
High revving small blocks are a blast in these cars.
