1970 Dodge Dart 318 upgrades

Tnx TMM. I'd vote for more low end torque any day for the daily driver app that the OP mentions... which directly translates into more mid-range HP. Broader torque curve = easier/funner to drive in a wide variety of situations.

That Howards 711381-10 cam has a very large amount of lift for the duration, compared to everything else out there; I was not even aware that there was any offering in that duration with that amount of lift in a hydraulic FT cam. VERY interesting; no wonder it wins on your comparison.

Though IMHO it's not suitable for the OP with the lift numbers and the stockish setup. And anyone using that Howards cam better have their valve train set up right to handle the very high ramp rates.

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

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

FWIW, the engine in question is likely in the 7.8-8.0 SCR range.
