Re: RE: [Chevelle-list] Chevelle Hell
This is a long shot. But when I was looking for the intake for my 283 I took notice that some older manifolds needed a bit of grinding to clear an HEI and some it just wasn't going to work. Of course I can't name which ones. Anyway, any chance they were grinding for clearance and went a bit deep. (and made a vacuum leak in a hard to see spot) Like I said, a long shot but I thought I'd toss it out there. Pete Geurds Douglassville, PA
RE: [Chevelle-list] Chevelle Hell
I have had a vacuum Dashpot (On the distributor) with a tear in it and it would run but pop when the RPM were raised and the vacuum raised. Disconnect it and plug the Vacuum line and test it out. mike --- John Nasta <[EMAIL PROTECTED]> wrote: > Yes. It pops when there is detonation while a valve > is open.

Re: [Chevelle-list] Chevelle Hell
180 it would not even come close to running. The power supply for the breaker point distributor is routed through a resistance wire to drop the voltage and prevent damage to the points. A bypass wire was also used to supply the distributor with a full 12 volts at startup. On the other hand, an HEI distributor requires a full 12 volt supply. here is a link on how to do this Ray's Chevy Restoration Site -- HEI Conversion
RE: [Chevelle-list] Chevelle Hell
Yes. It pops when there is detonation while a valve is open. That’s a timing issue. Is the vacuum advance working? Has the cam ever been degreed? I assume we have not ruled out the distributor being in wrong or the timing being set wrong due to a slipped damper.

RE: [Chevelle-list] Chevelle Hell
p.s. you can put a dowel or even a plastic straw into the spark plug hole so that you can see when the piston is at the top of it’s travel by whether the dowel/straw is moving up or starting to head back down as you manually turn the engine. Obviously you want it to be long enough that it can’t fall into the engine completely, and you don’t want to try to crank or start the engine while it’s in there. Keep in mind the possibility that your vibration damper may have slipped. If that’s happening, get it rebuilt or replaced asap. -Original Message- Pull the #1 spark plug and put a cork firmly into the hole. Turn the engine over by hand until the cork pops out. That’s how you’ll know that you are on the compression stroke and not the exhaust stroke. Turn the engine until the #1 piston is at the top of its travel in the compression stroke, then check to see if the timing mark on your vibration damper is lining up to the zero on your timing scale, and whether your distributor is pointing to the right cylinder. Rube Goldberg says that if the distributor is 180 degrees out, you can just install the ignition wires 180 degrees from where they’d normally go, and everything would work just fine. John Nasta

Re: [Chevelle-list] Chevelle Hell
I had that problem with my Nova right after a dist was installed. It needs to be 're-stabbed', as in its installed a few (or many few) degrees off, take it back and demand they fix it. - r0b On Mon, 12 Jul 2004 22:25:39 GMT, rick schaefer <[EMAIL PROTECTED]> wrote: > Did it ever run right after you had the HEI installed.
