Re: YJ Buildup
Love the sb 400 chevy, one thing to watch out for, and forgive me because it's been awhile, but I believe you will need an externally balanced flexplate for the 400. Since it was never mated to the 700r, you will need to get one off a newer small block, and have it balanced for a 400. Unless, of course, the old 400 flexplate can mate up to a 700r touque converter. I had this problem with my 400, I tried to mate it to a 4 speed, but supposely 400's never came mated to 4 speeds, so a machine shop had to balance a flywheel for me, no big deal, it cost $75 i think.
