Before I even consider...

Just so you know Will, yes I remember your parameters, and I am in no wise dissing yours or anybody else's current combo. Just trying to save OP some heavy disappointment.
That cam in a stock engine, and 3400pound chassis will want 3.55s or better and a 2800TC or better. Then it can be fun. But that is what?at least $1000 extra cost cuz of the cam. If OP is happy with about 216* then a 252 fast rate or a 256 nearly as fast rate, and a split-pattern for logs, is a waaaaaaaaaaaaaaaaay better pick, and no headers even required, just some hi-flow logs; call Treblig
The 252 to 256 can use a 2200TC from a 340, and 3.23s will do just fine.
Oh yeah, and about that 252 cam, If you had decent compression and patience, Ima thinking you might be able to get point-to-point fuel mileage in the mid to high 20s;if that matters to you.A spread bore will help you with that.

But if you are stuck with 2.76s and intend to keep them, then I think I would up the TC to 2800, depending on OPs goals
