I really liked my '41 Ford with a hotrod 59L flathead, even though it couldn't make it to the beach without a stop to let it cool down.
The '52 Plymouth that I stuffed a Hemi engine into was great. Unfortunately, it was a summer car because there was no room left after the engine swap for a heater.
I guess my top favorites would be my '58 TR3 with the engine bored out bigger than a TR4 and my 383 powered Jensen Interceptor MK3.
