What do you think about this 318 guys.

I‘ll run some numbers in a bit on a 426 that will make peak TQ at say 5200 which should get you a shift point of 6500ish.

I think youll be surprised by the size of cam you’ll need.
This is all next year stuff.. so no biggy right now, just bullshittin. And i am more about reliable than peak power.. no point in getting 45more hp if it ends up in a oily pile on the ground
