AA Engine
Are all AA engines Diamond Blocks? What is the difference from an A engine and a Diamond block?
Thanks, Phil

Re: AA Engine
Diamond blocks did not come in cars or trucks. The only difference between an A engine and a AA is the serial number starting with AA.

Re: AA Engine
The AA indicated the engine/transmission assembly was intended for a large (AA) truck. The engines were the same but the transmissions were different for the large trucks. The diamond blocks were post production replacement engines.

Re: AA Engine
The 'DIAMOND block is built with hard seats in the exhaust and the Camshaft is a ''B" Style. The A and AA blocks use standard valve seats and standard "A" camshaft.

Re: AA Engine
Not all Diamond blocks had hard seats.
