Post romp'in in style

Anyone ever run edelbrocks RPM cam? If so then did anyone have problems with this bumpstick on the street, Edelbrock promised me it was 100% streetable but I'm beginning to have serious doubts. Symptoms include surging that can't be taken out from the carb tuning or dist. timming. Without running so little timming power really begins to fall off.

Normaly you have surging because your retarted. (No pun intended) Advancing should smooth it out. The 1st thing I would look for is a vacuum leak.

I wouldn't use starter fluid, use wd40 it works good, starter fluid could do damage if you use too much.

It's Garenteed not to have vacuum leaks. Your olds is a big block allowing it tolerate more cam. I'm running a 355 with this cam. runs really well except for the darn surging at cruise speeds,at say, a few degrees of throttle opening. I can't even garentee the carb is even out the idle circiuts! Case anyone needs to know cam pulles 10' vacuum at idle and 14-16 at 1500 RPM.

Propane is the proper and safest method of determining a vacuum leak or lean run condition.

It requires a wand with a flow regulator. You put the wand tip to the carb/throttle body opening and slowly open the valve. Once idle has stabilized, you pass the wand over all suspect air inlet gaskets until the idle stabilizes again. You found your leak.

The trick is to keep the propane bottle upright as if you tip it, liquid propane could be released subjecting you to fire and/or explosion.

What I fear most is someone shooting either or carb. cleaner onto a hot running engine. Same with WD 40 as it has kerosene in the mixture. The above also make a mess on the engine and stain painted/polished parts.

PS; Also make sure you know where the shop fire extinguisher is located before attempting any of the above...

Propane in any form, gas or liquid is extremely flammable and easily ignited by a spark. I can just see some kid dragging the ol BBQ propane bottle into the garage, hooking a hose up to it and cranking open the valve while looking for a vacuum leak around his manifold. O my gosh! theres the distributor...KA BOOM!!!

Question

Then do you find it odd that carburetors are calibrated to an emission engine application with propane?

I said wand. There is a special service tool available that is a reinforced hose with a twelve inch aluminum wand attached that has a regulator to control flow.

If you think propane is explosive, what about ether or carburetor cleaner?

How about a little help here 4-Jaw?

4-jaw. I have been trying all afternoon to fill a Coors can with propane. How do you get it to saty in there? Maybe you use Molsen Gold cans instead?

I understand what your saying, But 4 JAW did,nt make it to clear on how to use propane. Some one could hurt themselves and others. If you have a regulated wand with the shut off button on the handle thats fine but I don't think to many back yard mechanics have such a tool. Next time your in a smog check station ask the guy, when was the last time he used his propane bottle in a test.If and when they do use it in a test its introduced to the engine thru a vacuum source. (I think)
Ether and carb cleaner are more dangerous. Spray some around your EGR valve when its by-passing and you may have a good size fire on your hands.
Anyhow I did'nt want anyone to burn down thier garage.
