Yes, low boost. We think the max boost for a stock engine with the stock ECM should be no more than 5 psi. I believe Mat's car (single turbo on a stock engine) was running 6-8 psi and was getting 550HP but he eventually lost a head gasket. You'll have to ask him the specifics...

$10k does not include labor.

FYI - I'm using the stock crank and rods on my 374. The engine builder said the stock internals would good to 1000 HP. He did however perform some lightening and stress relieving on the rods. I believe all the engine work and parts for my 374 cost around $9500 even with Ron Woods Head Studs. The goal is to eventually up it to 15 psi...
