Thread: Piston position on 383

Tweet

Bass Ackwards.

Stand beside the motor and look at the location of the spark plugs, referenced as top to bottom of the heads. They are on the bottom of the heads. You know that the spark plugs screw into the combustion chambers, so you know therefore that the chambers are on the bottom side of the head as you stand at the side of the motor and look at it. Therefore you know that the dish or dome that has to match up with the chamber must be on the bottom of the block as you view the short block from the side.

Before you begin bolting the motor together, tell me about the piston compression height in the block and how you engineered the squish and what the squish measurement will be. This is perhaps the most overlooked aspect of amateur engine building. Do you know the block deck height? Do you know the stack measurement? Did you cut the block decks to fit the stack? Don't be embarrassed if you don't know, it's OK. But let's get it worked out before you make a very costly series of mistakes.

I haven't seen any updates since your last thread, so I have no idea what the final plan was.
