6-pack intake manifolds

I purchased mine about 5 years ago right when the market was drying up. Took me about 6 months to find and put my set together. I highly suggest not use old core carburetors, you can have too many problems with just one carb let alone three. Original TA manifolds will not have numbers on the water passage near the thermostat. All 340 manifolds were aluminum and the Mopar replacement manifolds were also cast by Edelbrock and our virtually identical. the system is very powerful and dependable when it in good shape. Idol is definitely the Achilles heel I find it to be quite sensitive even variation of temperature of 20° in water temperature will make the idle jump around 200 RPMs up or down but I can live with that it's an awesome rare system and always a crowd pleaser at the shows. Good luck on your quest!
