I have been driving my 62 390 since Nov 1969 . I have always had stock mufflers and resonators and I enjoy the fact that it is very quiet . In 2000 I put a new dual exhaust system on it and again it was very quiet.
Recently I repaired the intake manifold as the choke tube was leaking so i ordered the Olson block off Gaskets. When I started it up the exhaust note had become much more aggresive. In short I hated it !
I tore it down again used stock gaskets and the sound returned to normal. I have a friend with a 63 that did the same using Olson gaskets with a single exhaust and it was much less aggressive sounding and we both agreed it was not a problem. We both used spacers in place of the heat riser.

I assume it has something to do with a crossover pipe when using dual exhaust. The intake exhaust path is serving the purpose of a crossover pipe. With single exhaust, both sides are routed together so a crossover pipe would make no difference. Does your dual setup have an added crossover pipe?

While checking my Carter carb with engine running, I took the air cleaner off and there was a very loud hissing sound of air. I placed a piece of paper over the carb and it didn’t move up or down, is this normal?

Hey everyone, has anybody done a Vintage Air AC/Heat setup in their car? I want to bypass the old vacuum setup and go with a Vintage Air Gen 2 model. Before I get started, does anyone have any experience with this? (Which model to go with, do’s and dont’s, etc.) It looks pretty involved. Any and all info/pics would be greatly appreciated. Thanks!

I would prefer to be as original as possible. Thanks

My son, unbeknownst to me, had all three of the horns on our 1963 Eldorado completely restored. We had recently added the Eldorado trumpet horn to the two standard horns and the sound was not very good... we had heard good ones so we knew something was not right... but there was not much we could do to get better sound from the 3 horns.
There is a restoration service called The Horn Works who my son…
