First, I would like to wish everyone a Happy 4th.
1. The 440 that I recently purchased in my 69 Roadrunner had numerous previous owners. I found a mechanic that had did some work on it a couple of years ago. He said that he ran a scope down the spark plug hole and could read the top of the pistons. He doesn't remember the brand name stamped on the top, but remembered that he said something about being bored .30 over. If that's true, what would be the true cubic inch now?
2. In the market to purchase a new starter; thinking about a mini high speed. They want to know how many teeth the flywheel has. Without counting the teeth, is there an easier way to find out?
3. The car has a Dyna rear end. Don't know what the gear ratio is. If I mark the rear tire and the drive shaft, what's the calculations as to the number of turns each that would give me that ratio?
THANKS IN ADVANCE
