I know Parish went over 1,000 HP to the wheels in his boosted iron block 408 with single turbo and 4L80 4x4 trans.

Billet caps, Girdle and Hardblock/short fill in the water jackets.

Everything possible to keep the bottom end lined up and true...

How much power are you expecting to make?

how many passes? FI? what rotating assembly?

Also who makes billet mains and approx how much should it cost to line hone/install them?

Am i better off buying an OEM block from the dealer or finding a used one? PM me if someone has a spare in good shape for sale.

I made 1700hp on a engine dyno with a 6.0 block, this would have been somewhere around 1200hp at the tire. I ran the engine quite e few runs on the dyno, and maybe 20 runs at the track with great results. I have a block prepared the same way that I will sell for 1200 dollars. It is filled water jacket, W2W girdle and billet mains. It will come with custom main studs and 1/2 head studs, honed with torque plate fresh for 4.030 bore.

does that price include the block itself? that seems like a great deal. are the water jackets completely filled though? how would that be on the street?

also, can you machine my l92 heads to fit 1/2" studs?

1200 Would be the block, with a fresh hone ready to go. The block is filled up to the water ports for the water pump. It could be used for a street strip type car, but not for long highway trips. It may need a oil cooler if driven to much on the street.
I could machine the heads to fit with 1/2 studs at additional cost.
