1970 Dodge Dart 318 upgrades

he can't use a lot of lift
pocket porting increases flow at similar lift but extra lift does not help much unless pro ported
that said
Engle and Crane have some .904 lobes that have a lot of area with easy to build lifts
actually if he is the 9:1 area Jones motor home grind is outstanding
50 % more duration .275 lobe lift than the Direct connection 260 cam and it wears well - you get what you pay for
Jones Lobe is 264 and DC 260 is 284 @.004 I ran cam doc--so which builds more dynamic compression?

That SUMMIT 6901 cam is 276/288 so it's a little shorter than the 340 279/289 but both are Wide LCA you advance them any more and in and ex opens too early
cheers
