Help me i recently bought a plymouth Valiant scamp and i need some tips PLEASE!?

Question

Is there anything i can do to my 72 Plymouth Valiant scamp without buying new parts to make it louder or faster? Or any suggestions PLEASE HELP I AM NEW TO THIS OLD CAR STUFF!!

Answer 1

As the previous person stated, there isn't a whole lot you can do. The Scamp edition could have the slant six or 318. If it is the slant six, unless you can find the ultra rare 4bbl manifold and carburetor from the late 60's, then there is not a whole lot you can do. And to CORRECTLY change from a slant six to a V8, you have to find a Valiant, Dart, or pre '70 Barracuda and get the whole engine crossmember (called a "K frame") and the torsion bars to go with it. The reason for that is that Chrysler designed the slant six and V8 crossmembers different. So without spending mucho dinero, you are basically stuck. And even if it is a 318, once again, it takes many pesos to bring them to life. I applaud your desire and effort to get an old car to have fun with. Sadly, you have chosen the wrong make to find a lot of used parts to fix it up, or aftermarket parts for hop-up purposes. I'm not saying it can't be done. It can. But there is an old addage in the car circles: "Going fast costs money. How fast do you want to go?"

Answer 2

AHHH! Whatever you do, don't take off the muffler or air cleaner. And you don't have cats on this car.

The question, is, how fast do you want to go?. With the six cylinder engine, these were really just taxicabs. With the small eights, they were respectible, but never overpowering.

If you're on a tight budget, a tune up is about all you can do, so that it's running as well as possible...new spark plugs, points, distributor cap, and rotor. Adjust the timing and carburetor. Then evaluate. About the only other thing you could do cheaply would be to replace the muffler with a cheap glasspak.

If you need more, you can get better off the line performance by substituting a lower rear axle ratio. It's possible to build a dual exhaust system for either the six or the eights, although the parts for the six will be very hard to find. There are manifolds that allow you to mount bigger carbs. You can replace your automatic with a manual from a Barracuda, Challenger, or Charger. Finally, there are performance cams available for any engine you might have. Any of these options will cost $$$.

Doug Dutra, who sometimes makes dual manifolds for the slant six, published a DIY cookbook for splitting the manifolds, but it requires some advanced skills:

Answer 3

take of the cats (shouldn't be any), or the whole exhaust.
take off the air filter too.
