I'm planning on building a 410 this summer and I'm figuring out piston heights between a couple 390s that I have. I have a book by Steve Christ How to Rebuild Big Block Ford Engines which I get a lot of information from. There is a chart in the book on deck height and a formula on figuring out the deck height for mix matching parts. One thing that is holding me up is that has a couple different pin heights. One of the 390s that I have is a 69 which the pin height is
1.775 and the other is a 70 which has the same. It also shows for a 390 68-76 the pin height is 1.680. I will be able to use a 390 piston that has a pin height of 1.680 and have .012 deck clearance. Could the two different heights be for a 2V and the other 4V, or is it between a car and a truck? My 69 390 came out of a truck and is a 2bbl motor the 70 came out of a car and I'm guessing it came with a 2bbl, I got the motor without an intake. I would like to build this engine with stock parts. Is there a piston chart that has the pin heights for all FE's a guy could get? Anyone have any info on this?
