Hey guys-I am building a turbo 4200 for my '65 Nova. Someone was asking about the ability to use the cam phasing....here you go!!

This kit will do it all....a little more $$ but well worth it in my opinion. I can also give you a great contact for purchasing and tuning if interested. I will be getting my Autronic this winter. I hope this helps and I will help in anyway that I can, although I am learning more than teaching probably!
