BIG thanks for the fascinating discussion AND pix of the Lycoming V-8! Damn the Great Depression! Lot's of FAB stuff just faded away in the '30s for lack of selling enough units. For comparison's sake: Since the Oakland/Pontiac V-8 was mentioned, it DOES appear the mechanics of this engine didn't escape the attention of Lycoming engineers, IMO. The last of the Oakland-made V-8 were used up in '32 Pontiacs, making way for the long-lived straight eight, as Pontiac was moved down-market from the fairly lofty perch Oakland had occupied. (Another victim of the Depression!) FlickR member Dok1 (Don O'Brien) posted this nice shot of a '31 Oakland V-8 from a show in Portsmouth, Ohio. Some internal works of the Oakland V-8 (1929-32).
The Tucker used an aircraft engine, a Franklin. Tucker tried Lycoming, but couldn't get it to work. H0-335-6 horizontally-opposed OHV 6cylinder, 334.1 cubic inches (5.475 L), (4.50 x 3.50 in. bore x stroke), 7.0:1 compression ratio, 166 bhp, 372 lb·ft (504 N·m) torque
Bringing up a ''zombie thread" on this topic. Setting the valve lash on this one, a 37 Cabriolet with great history from new. Someone had a SBC flashback and set the valves at .030, but the OEM spec is .008-.010. Enjoy the pics, and I'll get more details of it finished and add more yet. Last pic is how she came in to prep for certification over Labor Day weekend.
