[TR] Customized TR3

[spook01@comcast.net]

The small block Chevy WAS heavier.  The Ford used precision located cores, which allowed thinner and lighter castings.
The Chevrolet used older, shift-prone sand cores, thus thicker walled castings.
You can argue that this let Chevrolet engines accept more bore size increase, but it made for heavy engines.
Funnily, I had a 1100 Sprite that embarrassed a guys 327 Impala one night.....at least into third gear!

4 speeds were a lot less common back in the 60s; also bigger and heavier.
It might have been chosen for the smaller size; but I'd guess it's just what
came out of the donor car.

Ironically, though, I'm not sure it would be all that much quicker than a
souped-up TRactor motor.  Back in the 70s I had a TR3A that would embarrass
a stock 289 Mustang, especially if he didn't take me seriously.  They were
fractionally quicker in a fair fight, but if I got a car length lead first
....

And if memory serves, the 283 Chevy was a heavier motor than the 289 Ford.
