SOLD SOLD SOLD For sale is an original matched set of 348 Tri-Power Carbs Base plates have a little rust but nothing major. Shafts are tight and move relatively freely, they have been sitting for about 30 years so a little clean up and they will move fine. They came off of a complete 1958 348 that i had, and it looked to be all original, so i'm figuring they are 58 carbs as well. no linkage but good cores to build a tri-power setup, yes they will need kits and a linkage, these work great on a small block with the stock jets and rods. $200 plus shipping. I take Pay Pal, USPS and personal checks from Alliance Members. pics coming this evening.
