This is an all aluminum Donovan 417 hemi with a Littlefield 6-71 blower that is complete from hat to oil pan. All parts are period correct for a nostalgia top fuel engine. Venolia pistons, Brooks rods, Donovan rockers, Donovan valves, Crower injection and hat, Mickey Thompson valve covers, Vertex magneto. The hat is signed by “Big Daddy” Don Garlits as shown in the pictures. As it sits, it is set up to run 85% Nitro and 15% alcohol. On a mild tuneup it made 1,850hp on the dyno. Short block is fresh with zero passss, the heads and blower were rebuilt 20 passes ago. In an altered this has been 3.91 in the 1/8 mile. The block is production number #105 which was made in early 1972 and has had zero repairs and is in great shape. This has matching Donovan aluminum cylinder heads stamped production number #117. The Donovan block was originally purchased in 1972 by a gentleman named Lyle Mason who was a crew chief for the top fuel cars of “Utah Charger” and “Sudden Impact”. Piecing all these period correct parts together would be nearly impossible with addition of the super low casting numbers. If you could go back to the early 70’s and remove an engine from a top fuel or funny car it would be identical to this one.
