Talk about luck the engine build started with Keith & Jeff Dorton from Concord, North Carolina Automotive Specialists Machine Shop. Being blessed a 2nd time Mark Porch at Robert George just up the street from Keith’s shop sold us a late 1962 421 SD short block that was stuffed in Roberts garage. Looking for an upgrade we had Keith use a better connecting rod and a lightweight Diamond Piston to spiff up the short block. Jeff started in on the alloy cylinder heads that we purchased from Edelbrock for more durability and a tick up in power. This combo required a bit of retrofitting when used on a 1962 SD block, Keith & Jeff made this work perfectly. The oil pan was hand-built as it would have been done back in the day, the kick-out is set up so the motor will not run dry on the tall banks of Daytona. Dyno results were 519 HP @ 6000 RPM, just enough to make this Hot Rod fly.
