I posed the following question on the Stovebolt forum almost 20 years ago and didn't get much response, as I recall. Maybe there will be more interest today.
For background; one of the first cars I really fell for was a 53 Buick Special 4-door with a Straight 8 and Dynaflow. I was about 9 when my folks bought it from my granddad. As far back as I can remember it was part of the family. Anyway, we kept it for about 3 years and traded it for a used Dodge. I have loved old Buicks, especially 1953s and Straight 8s ever since. For the past 30 or so years I have played around with Advance-Design pickups. Fast forward to 2020 and I'm thinking (again) about shoe horning a Buick 8 into an A-D truck.
Not the smaller 263 Special engine but the bigger 320 Roadmaster 8. Last year for it was 1952. The Roadmaster and Super got V8s for 1953 but the 263 continued one more year in the Special. I know the 320 Buick was used in some Flxible buses in the 40s and 50s with 4-speed and 5-speed transmissions. Some 5-speeds had 5th gear overdrive. Some of that stuff is still available...
I know, lots of hurdles to jump: motor mounts, radiator position, firewall clearance, clutch linkage, etc. Am I crazy? Comments? Thanks.
