Complete 6 pack find- not mine

Wow. Ive had 3 6pack setups on small blocks, all 340's except the current one Im putting together. 1st one was a basket case, Id bought when at Whiteman AFB Mo. Problems all the way till I sold it! Worked on and learned a lot about holleys and common problems with them for awhile. Second setup, I bought a decent set of mechanical carbs for and sold the vacuum carbs. Took about o month to get it right! Then I plumbed a hidden Nitrous setup to the bottom of it and ran 1 bottle thru it. Ran like a scalded dog! No traction what so ever. Took it to the track at KCIR, and didnt/couldnt get a good timeslip with the Nitrous. Left there and spent 10 more years at various bases. Now that Ive been retired for awhile, been collecting pieces for 4 years. Picked up a 71 Demon at Christmas, and completeing the metal work now. ( Have a 360 with a complete stroker kit, 6pack with mechanical secondaries.) AND... have a hidden nitrous kit (250 direct injection) to plumb into it. Lot of work to come! But knocking it out slowly with this extra time I seem to have till I go back to work.. more to come... will update more 6pack stuff after I finally start on the driveline.
