I also voted for a 370. It will have less Piston wear, and the pin location, as well as the piston it's self will make for a stronger engine.
You use a 4.030" Piston, a 6.125" Rod, and the stock 3.622" stroke.
As for the turbos, do you have "ultimate" goals? As far as horsepower is concerned at least?

Bump. Things were on hold while I was doing my nitrous car. Back on schedule. finally sending the block to get machined. Im going to be using wiseco pistons with lunati rods, unported 317s and a custom grind.
I don't have ultimate goals on what I wish to make, although I would be happy with 800+ reliable whp.
Does anyone have results from running a similar setup?

I run a faceplated t56. My hot/cold side is all custom, but it's laid out pretty similar to the new huron t4 twin kit. I haven't had it to the track or dyno yet, but in the car's previous nitrous life it would go mid-low 10s at 135mph weighing 3900lbs which is about ~675-700rwhp. I haven't weighed it with the turbos but it should be similar weight. I can tell you with the turbos on 10psi it's killing 28x10.50 MT's on the street like it never has before, so it's making at least the power it did on the nitrous. I've turned it up to ~14psi a couple times and I can lay into it in 3rd at 70mph and stripe the highway as long as I stay in it.
Did you ever take it and get track/dyno results?

Yep it made 663/661 on ~11psi and 890/813 spinning on the dyno on ~18psi. Our local 1/4 mile track went under this year so I road tripped to the closest 1/8 mile and just made a few shakedown passes. On 18psi it ran high 6.50s at 115mph with a mild 3psi launch and 1.57-.58 sixty foots. Race weight is 3750.
