wierd motor
I bought a motor from a guy the other day and it was one of those pieced together motors. It has a 2ua crank, C7AE-B rods, and 410 pistons. According to my books that is a 390 crank and 428 rods. Which would make a 390 with about 7.8 to 1 compression. Whats up with this? Why would ford put a motor together like this? The guy I bought it from says he had a 360 at one time that had more power. Now for my real question. Could I use the crank and pistons and throw in some long rods I have and get some decent compression?

390 rods = 428 rods, center to center length anyways.
What you have is a truck 390. Ford made lots of 'em in the 1970's.
You could put long rods in it to increase the compression, but it would not be ideal. All you need are different pistons. Look for ones with about 1.778" compression height, dish volume to match your desired compression.
