Are shift kits worth it? If so which kit is the best? I have a 72 lemans with a th350. The engine is a 350 with headers, dual exhaust, and edelbrock 600 cfm 4 barrel carb. I have read transgo is the way to go but they have a number of kits and I would like opinions on which one would be the best. Most of my driving is street, no racing. Thanks!
