Once again, I’m digging up stuff that’s already been talked to death.....I believe buying a new Carburetor to sit atop the 400 bb in my ‘63 Polara will solve several issues.....Originally, the 400 was built for a ‘65 Coronet, however, my love for all things MoPar offered in ‘63, led me to a poly equipped ‘63 Polara drop top I had tried to buy before with 66,000 miles. I replaced the K member and also swapped out the rest of the ‘65 Coronet’s running gear my MoPar Bud rebuilt for street and long hauls. The 400bb was built to run on pump gas (which was much better 20 yrs ago I believe), with a eng kit Mancini recommended for longevity all around driving, yet fun, and has clocked approximately 7,000 miles. The piston are 9.5:1, factory 906 heads redone by a machine shop with 46 years exp, hardened seats, etc, etc.a Comp Cam (similar to the purple), motor has always preferred 90-93 octane), and I only used the ethanol mix crap fuel if I had to, or as recent happening, accidentally. The ethanol mixed crap would stink, cause the car to run like shit, and burn the eyes. The car sat driven rarely during a three yr stint 2014-2016 ish while I dealt with a major health thing, a shop replaced the carb gasket, and intake gasket, (no longer in business), which was probably a mistake. I’ve also had a trans shifting problem, which I’ve posted, and had many members offer tons of greet help, but a member recently sent me looking at kick down linkage as the culprit I believe were on to something or headed in the right direction to fix, obviously the shop did NOT reconnect anything properly, but it has ran great until recently, moving from 2000 ft above sea level to 840 ft, it runs fair, but seem lean or gassy as hell. My question, Or what I would like opinions on first...... has anyone else had issues with gas / fuel, finding ethanol fee gas, and my main issue, has anyone else recently bought/installed either a Holley Carb or Carter, and which offers more options for detent, accel linkage / cable brackets, etc. to be connected and work smoothly? I guess I’m sorta picking up where I left things half a&@ done over the years, I’m hoping for easier cold starts, a working idle switch to help when the AC compressor cycles, and properly connect the passing gear hardware/ detention/kick down etc, back so all to that works properly, the ...Holley or Carter? I’ve read through many previous threads about similar issues, but never found anything that really addressed all the shizzle I’m trying to nail on mine here, probably not many are as dumb as I feel like I am these days.....ThankYou again, and I’m very grateful for everyone’s time opinions, input!
