OG Carb. Replace or Rebuild?

[fadingcaptain]

Hi, I'm new to this forum but I'm sure glad it's heere. I have a 70 Lemans, with the 350 5.7, and a 2spd pwrglide. It is a 4dr and it's a great car. It's all original, when I bought it the jack, spare, tire iron were all intact with the little rubber sheath and there is NO rust on it. Came from the Central TX hill country. I will post some pics later. I'm just looking for advice for anyone who has been down this road.

It still has the original distributor and Rochester carb. I am doing some upgrades, and I've been looking at replacing the distributor but would it be worth it to replace the carburetor right now? I can't seem to find another two barrel and I don't want to replace my intake manifold just yet. Any suggestions?

Thanks!

why are you replacing either one as opposed to rebuild? Parts are readily available.

RE: replace/rebld

Well, I'm still trying to figure that out. Someone told me it needed to be done replace the carb, for fuel efficiency and replace the old distributor with a (MSD ready to run), to eliminate timing problems from using points and condensers. Any advice on these?

My big thing here is trying to get this running efficiently on a budget. Not too concerned with high performance gear right now but I do want it eliminate any problems with older parts.

The car runs with no problems, well I say that but it needs a new exhaust BIG TIME: i think the muffler may be collapsed b/c it keeps running kind of hot; and I need to replace the coil springs b/c i keep bottoming out and every time that happens it loosens my flywheel and I have to jack it up and tighten it.

Springs are coming in next week, and once those are on I will probably go forward with the exhaust.

if your on a budget replacing the distributor without a specific problem makes no sense. Points and a cap and rotor are alot cheaper than a new distributor. Replace the plug wires also. If you want to get rid of the points install a Mallory Unilite conversion.
Get a rebuild kit from, I believe the company is called the Carburetor Shop, you can find it online.

Re:

Hey thanks a lot, I'm going to order one (way cheaper than an msd),of those and install it with my springs next week. I'll post some pics and stuff. It's been a strong running engine so far and Any other recommendations, on getting some interior parts such as the door panels, and side board panels; the old stuff just seems to be disintegrating. The dash is split and I am looking to replace it with a new one. I'm looking at putting in the carpet myself and have the seats re-upholstered at a local spot here in Houston. Thanks again~

for parts you can try places like www.amesperf.com, www.performanceyears.com, also pick up a magzine called High Performance Pontiac, pages and pages of Pontiac vendors.

Hey try petronix, it replaces points with electronic module. You can definitely rebuild your carb. Cliff Ruggles is another place you can get your carb rebuilt.
