options b and c will work:devil i think that wil be the best bet.............;) or buy an r:blah :macho

[WildCatRacer]

id go with the full race porting. call up mike at For Dirt Only...he does great work. I wouldnt put a carb on unless you have more work done on your motor. the cam would be the cheapest route and if you get a mid range cam you dont have to hardweld the rockers so it will run around $150.

I think the carb. I have read reports of 2-3 hp gains on stock engines. faster response and easy to install. Besides you have a cam already and with a stock bore piston your not moving that much air, if you were running a 440 it would be another story. Just my .02

carb or porting
