A Daytona engine built to standard specification with the exception of higher compression Razzo Rosso forged pistons. Connecting rods were beefed up with RR/ ARP rod bolts. For reliability and reduced maintainance costs, the distributors were converted to electronic triggering with Pertronix kits. This engine was originally built by another shop and had coolant leakage issues. We disassembled and rebuilt the engine after the problems were fixed (liners too high). The engine was dynoed as shown in the photo with standard exhaust and air filter housing in place.
