Re: How can i get more top end from a \'73 Scorpion Super Stinger 440?
not sure, but if ya know what your doing, a little porting can never hurt.
clean up the intake and exhaust ports, take the roughness out of them.
not sure really what else ya can do with these older machines.
i have the 1980 txl on the readers sled page and i did the porting etc. and it helped somewhat. play with clutching and gearing too if ya want.
hope this helped, if not, ah well.
