anyone hear of a h-p big block sawtooth 318?

Have heard it also referred to as "old style 318".

same term-of-endearment has been applied to the LA 318 as well :sad11: , especially since there are no less than ~3 different series here :
- Polysphere
- Lightened A-motor
- Magnum

I believe that the 318-3 ( marine & industrial ) has a forged steel crank , but then again so do the 273's .
Definitely not worth that thousand ... unless maybe the motor needs zero internal work !
