What cam to use in 340

In stock form, the J heads can run 13's without to much effort and into the 12's & 11's properly ported. Running faster than an 11 with a OEM head will require a fully ported head and a very light eight car. Not to mention some other parts that are probably not so desires me for the street.

I like my Edelbrock heads. They made it easier to perform at higher levels quicker than a OEM head.

Bang for the buck wise, a lot depends on what your doing with the car, what you can do rather than pay someone with and the abilty to wisely use what you have to the best possible outcome.

A ported OEM head that can go 250 cfm has the abilty to make an easy 450hp and the power to run quickly. Lighter weight cars run quicker than heavier ones.

Off the soap box now.....
