..that's kind of what we think..thanks..

If you used the AIRPOD system, it has the small reserve tank built in , but way under sized. you must use a reserve tank for a big car.

go with the biggist compressor you can find , my buddy that has done 3 systems now use one that is 4 cfm ? I think. NEVER run the compressor on battery alone,,it kills them. this is a similiar compressor..

also make sure your pressure switch is cutting in high enough, the bags with a big car need at least 150 psi to make it move.

add shocks to the front if you havn't done so, it greatly improves the drive.

I'm no expert, this is what I've observed helping with my friends projects.

he's done a 78 Fleetwood sedan, 69 Eldorado, and 96 Caprice....big cars take big air !!

...thanks a million Roger. We're going to see our mechanic today. He runs a high-end performance shop and has done a lot of work for us over the years. He really knows his stuff so we're fully shock-dampened at all 4 corners. All the old shocks and springs were toast so the ride and handling alone should be much better. We did ball joints at the same time so everything should be really tightened up. But I think you're right on with your advice re a big pump and a reserve tank. For a big car it seems like the only way to go..I'll let everyone know where we end up for your future reference..
