Cut 50% weight from valve, spring & retainer.

In this. episode 75 part 6, of uncle Tony’s ’Mission Impossible’ project to make 318 hp from a 318 SB Mopar using the original 256 cfm 2 brl carb DV explains some of the necessary stratagies. Part of this is a huge valve train mass reduction by parts selection. Best yet it is all done on a very low buck budget and even better the parts he show to use are very much wolves in sheeps clothing. In other words some very much under-priced hi-perfromance parts good for more than just this project.
