P = Production Frame
P = Production Engine
PP = Production Pushrod Engine
G = Gas
Or something like that.
Thanks for the link.
Just been reading and PPP and PPG both appear valid classes - Production Pushrod and Pushrod Gasoline. PG seems to allow for tuned engines against the standard PP.
The first P is for a production frame, the wording says "the public must be able to purchase 500 frames through retail dealers", not sure what would happen if you rolled up and try to buy 500 961 frames :?
