Help! Motor is freaking out on me... - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hey, my truck has been siting in my garage for the last three weeks, i finally got the new valve covers and air cleaner with spacers on there... I started it last night, and it kept going border line dying.. It wouldnt die, but you could hear that it wanted too... The exhaust right on the passenger side headers seemed to sound "lumpy" as well.. What is the problem? This is the only V-8 i have been around, and i noticed after the 1 1/2 min of idling the headers were really hot.. Maybe they are usually that hot, but i pressed my finger on them and damn near lost my fingerprint... The new valve covers are edelbrocks, with a K&N Breather on the passenger side.. The truck is an A/C truck and i didn't have any plugs, so i just put a piece of tape on the vacuum thing for the a/c that went to the original air cleaner....
What is wrong with my motor? Could the air breather on the new valve covers cause this? please tell me that its something small... Its got 87 octane in the tank, but that has never affected it before... It just sounds real lumpy, especially on the passenger side, and almost wants to die... Could the spark plug wires be in the wrong order? if it could be.... how can you tell where #1 on the distributer is?
help!

There may be some new-fangled way of doing it but as far as I know if you want to determine a cylinder location on the distributor you gotta get #1 to TDC (pull out the spark plug, stick your finger in there, have someone bump the ignition until it comes all the way up). Then pull of the cap and see what position the rotor is in. That's #1.

The headers get fairly hot I mean hot enuf to never touch them ever again? Got to many burn marks on my hand to know better.

Double check to make sure you do not have any vacuum leaks, sounds like you have a hose disconnected somewhere.

What "a/c thing" are you referring to?? There was a control valve mounted to the air cleaner for the air diverter valve. plugging the line from the carb should be no problem though.

I'm from Great Falls myself, parents live in Billings. Welcome to the board!
