who sells mods for 670 i need a 501 rotary valve .short carb boots, 8.mm base gasket. :hallo1:

try www.mcbperformance.com

Your doo dealer will have all the parts needed. Buy the short boots from a 95 Mach 1. The base gasket is a standard part as is the 501 valve. You can also modify your existing valve to get it timed closer than a bought one.

slowhand.....I would go to the crankshop for your mods,they have a ton of mods in there catalog for the 670,they also have the reputation to back them up.they also have a 740 big bore kit for it,it put's out alot of torque.If i were you thats where i'd go.

thanks everyone
