hello Im building a 2.2 to race dirt track,
rules say completely stock!
so how far can I mill the head and block?
motor is a 86 non roller, what cam is best, that you cant hear alot of lump in ?
any info would be great!
Thanks

 

If the rules say completely stock, that's what they mean. If you try to skirt around the rules, trust me, you WILL get caught. One tear down is all it takes...
