No mods as yet, but have purchased some aluminum racing heads from a friend. They are ford heads from a BOSS 302 and will be getting some roller rockers and an RV Cam for it. Honed out the cylinders and I think the block is a keeper. The Pistons are 10.5 to 1 flat heads with valve dishes in them.
Ford 8" rear end.
Got it from a coworker for a SONG. about $75. we traded an old shot gun and an Italian rifle. Total price on the guns when I got them was about $75. After he found out about the pistons he wanted it back.
