In addition to the post above i will have to say they were early rods, the pistons were forged TRW's probably close to 600 gms and the crank was a stock nodular iron crank. Didn't know it broke, drove it back to the pits and someone saw oil comming out a hole in the pan. I saved and sold the crank, the block i still have today and am putting it together for a prostreet truck. i also sold 7 pistons and rods. I lost 1 piston i rod and bent 2 valves. I still have the track 1 heads also and they are going on the same 406" blk. but with H beams, Lonati pistons, and Eagle crank.
