I bought a complete 1971 340 that has been sitting in a shed for 25+ years. I haven't picked it up yet but I know it has the original Thermo quad on it. I might be willing to part with it. If you haven't found one in a while P.M. me and I'll let you know. Thanks, Craig.
I have a top and a base that could possibly be repaired or used for parts. I also have a few of the original factory intake thick spacers PM me if interested
I think I have a thermoquad off my old 74 "340" cuda', it would definatly need rebuilt as it has been setting on a shelf since probably 1985, looks to be complete other than maybe choke stuff. If interested send me a pm and I will get pics for you.
