The results are in: 9 readers chose the dual carb / finned head version vs. the 2 readers who chose the turbo version.
Interestingly enough, nobody chose to keep it stock--the path of least resistance. And, thankfully, nobody chose the ubiquitous small block chevy (I have nothing against the SBC--it is a great, proven piece of well-designed machinery--it is simply not the direction I want to take with this project.)
I hope to return to working on the Studebaker soon--the work on the bass guitar is wrapping up nicely. There will soon be evidence of real, Studebaker-centric work here soon.
Thanks to all for voting!
