Yeah been wanting a ramjet for along time but I will do it on the new motor.
One bad Mofo! This used to be my dream motor. I would go with Ross forged if you ask me, they are well worth the money.

Technical Notes: 1 - GM recommends a Demon 750 CFM or Holley 750 CFM carburetor for ZZ383 applications.
2 - In 2004 GM redesigned the pistons and rings and they are .005" over sized now. This was done to better improve piston to cylinder wall clearance. The .005 O/S pistons and rings are the recommended standard size for all second design 383 ci engines. The first design ring and piston sets were: [Rings - 12522848 std. 4.00, Pistons - 12489437 std. 4.00" (piston & pin set).]
NoteΉ: The GMPP catalog states that the compression ratio is 9.1:1 which is wrong. The compression ratio is 9.7:1 for the ZZ383/425 where the compression ratio is 9.1:1 for that HT 383 which uses a thicker head gasket.
