Lonnie felt like having fun at the Nats, so he entered his '67 Coronet 440 in our AMSOIL/Mopar Muscle Numbers Don't Lie Showdown, and did very well. His 440-equipped Coronet features parts like a .030-inch overbore, with a stock crankshaft and Six Pack connecting rods. Since the cylinders are now larger than stock, a Set of JE forged pistons were used to fill the holes. Keeping it old school, a Purple Shaft 509 cam is used, and a set of 452 heads work with the Edelbrock Victor intake, and Holley 850 vacuum secondary carburetor. A set of tti headers and 3-inch exhaust kit works well with the Flowmaster 40-series mufflers, and what a sound it makes at full song.
A 727 is what Lonnie chose to handle the shifting, and Anglo's Transmissions fitted it with a 3,500 stall converter from TCI during the rebuild. Finally, a DTS-built Dana is filled with 4.10 gears and a Sure Grip.
What are all these parts worth on the race track? Lonnie tells us that he has run a best of mid-to-high 12's at 107 m.p.h.
