Hi Eric, If I were you I would put the 617 up for sale, and find a 670 ,much better engine,and easy to do small mods with nice improvements.

Hey Bud, don't listen to those 670 guys, my little mach1 617 eats them up.
Hurle your carbs out to 44mm put bbo and bb5 needle jets, set needles to 3 and 4, 501 rotary valve, drill the back upper part of the box 1 1/2 inchon each side. Jet up about 6 sizes to start.
So many things can be done to these mighty 617's. just to name a few.
