So this put me on the hunt for a new block. I was fortunate enough to find a mid 70's low mileage block that had disasembled, greased up and stored for the past 20 years ! I brought it to my builder who cleaned and verified it had never been bored, milled or nothing. The block checked out perfect. So i took the old motor apart, kept the good parts and replaced what needed to get replaced. While it was apart, i made the jump to a all new Comp Cams retro fit roller setup. After months of waiting it's now complete and installed in the car after being broken in on the dyno it came back with 460 horse power and 460 lb feet of torque. Now i just need some warmer weather to complete the remaining small items. Really looking forward to spring to enjoy cruising !
