So it's been a while since I've dealt with Foxes, but a buddy of mine is looking to purchase an 82 with a four speed and a 302. He's wondering the differences in heads off of a 289, 302, or 351W when it comes to Combustion Chamber size. He's looking for higher compression. Any help with info or sources on that matter would be nice. He also asked about converting from a 4 lug rear to a 5 lug rear. This was one of my plans for my fox before i got rid of it and recommended he go the 5 lug route, but it's going to take him a while to save up for the spindles, brakes, and wheels... The last thing he asked about was if it was possible to swap in a world class T5 tranny in place of the 4 speed. I didn't know if it was and said it may have to be a T45 ?? I said that when i had my 93 i wanted a T56, but I didn't know if they still bolted up the same in the 82s.. Any help with all this would be greatly appreciated. Thanks!!
