converter

I am looking to upgrade the cam later, and possibly the heads. I want to buy a converter now that will work for both possible scenarios.
These converters are not limited to one setup. They work within a certain range. You don’t have to change a converter unless you go outside it’s ideal range with cam, compression etc. Call Paul @ TA and ask if you would be best with their 11” or their tight 10” with your stated current and future plans. I’m thinking 11”
