X274 or Thumpr?

I know there are tons of post on cam choices but if you only had 2 to choose from which would it be? (I already have these 2)


I am putting together a 70 model X code 340 with .30 over pistons, RPM air gap intake, TTI headers and Holley Terminator EFI. It has X code heads as well. I would rather use one of the camshafts I have rather than buy another. I have a Comp X274H and a Comp Mutha Thumpr that I can use.


What would your choice be?


It is going in a 70 Duster, 4 speed, manual disc brakes. Its just a weekend cruiser but I don't want it to be to much of a dog, I want it to go when asked to. :)
