439 BBC short block. Machined and build at Wesco Racing in Jenison. Built this for my boat and used it for a little over a month, engine has 35-40 hours max on it. Selling boat and putting stock power back in. I have close to $3500 in to the short block. With afr heads, Marine Kinetics roller cam this engine made 525 hp. This would make a great engine for a 22-24' boat! If interested make me an offer.
