On the tire side, I put the Excelsior Radials on my 32 Cabriolet and they dramatically improve the handling and safety of these older cars ---> again, especially at higher speeds, around corners, etc..

As others have mentioned, I really like the E.J. Whitney alternator conversion and would really want to run the BEST headlight/taillight solutions possible ---> that could be either Halogen bulbs (they take a lot of amps) or a LED retrofit bulbs. Original lights at night are just not a great solution for a car you want to drive a lot.

Hey Kube: If you decide to hop-up that later flathead, be happy to help you in any area where you might have questions. More cubic inches and power are surely a help in pulling highway grades with a Columbia in the rear.

Truly, I respect you and your advice.
My plans don't envision nighttime driving, and I refuse to get on an interstate with these old cars. Crap, around here 80+ mph is the norm.

My vision?
A "barn find" appearance yet very reliable. I am confident I can get the reliability of the stock drivetrain.
Radials? Maybe. I do have one prewar Ford with radials that noticeably drives nicer than bias.

I am really looking forward to this project. Although a huge shift in what I have done for decades, methinks this will be a fun and mentally healthy endeavor.

I want to stress that I am sincerely appreciative to you and the others that have chimed in here.
Thank you all.
