Anyone with a few hours to spare should search for the following web sites:-

The Van Blerck Motor Company.
They made real engines, not those namby pamby midgets of 10 litres or so. Check out the reproduction 17 litre roadster from 1916. Wonder what the crankshaft of a 2369 cubic inch straight twelve looked like.

Mopar Performance.
Fancy a 9 litre supercharged aluminium Hemi V8 as a crate engine?

Practical Machinist.
For anybody with an interest in metal working. The antique/historical sections will keep old (and young) metal workers amused for hours.

Have fun.
