Stroke for 390 is 3.78", 410 is 3.98", (same as 428). Piston comp. distance for 390 is 1 .775", for 410 is 1.674". Rods are the same, 6.489"

I asked about 410 pistons and what correct compression ratio to run and the first thing they wanted to know is what is the cc's of the cylinder heads that your going to use ,,, and right now I didnt have then off to check yet . So
I dont know what the cost is going to run yet ,,,,,,,,,,,

A 428 crank and flywheel for $100??????????

Dude! You could do a lot worse. Try the search function; be prepared to sit for awhile while you skim through the posts.

as far as heads the stock 410 heads on it should be either a c6ae a or a c7ae aa wich are both 71.2 to 74.2 cc I have a set of d2te aa with 68.1 to 71.1 cc and a set of c8ae b 67.1 to 70.1 cc so I guess the 410 heads would be the ones to use with todays gas I want a drivable engine with good torque and throtle response its not a daily driver but a weekend play truck and hunting truck
