I bought a boat recently that had this 468 in it. I witnessed it run on my local lake all summer and it sounded really good so I bought it when the owner ran into some money problems.
The owner had it freshened 2 seasons ago with rings and bearings and did a valve job. According to owner it is a 4 bolt main with a steel crank and is .060 over. Rods are unknown brand of h beam with good bolts and forged pistons with pump gas compression. Cam was retro fitted with Hyd roller lifters and rockers. Heads are steel rectangle port and has high volume oil pump with what appears to be a moroso 10qt jet pan. Long block only but have the t ram and dual carb set up if wanted for extra.
I will get casting numbers tonight for anybody interested in them..
