yup call one of those guys and tell them exactly what you have and just as important its intended use and have one built to your combo. be 100% with yourself and the builder. a converter can make or break the combination. do it right do it once..
Calling an expert probly cant be beat , but cheaper by far if u just match the convertor to ur cam . gearing , use , and tires come into play too , but it aint rocket science.
A store bought one will work if u get it right , altho may not be quite as good as special built , but who knows w/o a comparison.
