28psi. LOL i dont think so. You will spend just more in mechine work than u do in parts for the motor. You are going to have to O ring the block and the heads to keep 28psi inside the motor.

348ci, 14-17 psi in the past, 110 leaded or C16.

New combo should make a bit more power but will still be dynoing on 110L.

How about a real horsepower goal instead of a boost goal. 28 pounds of boost on a pair of T3 60-trim turbos is a hell of a lot less power than 28 pounds of boost on a pair of T72's.

thanks for all the info guys 28lbs is not a goal it was just simply a figure i threw out there, knowing that its an extreme amount of boost just curious what kinda of setups are handling it, ill be spending alot more time reasearching what im going to do in the end, but hopefully it will be ready to rock and roll by spring.

thanks,
John Mitchell
