by Farmer Sun Aug 21, 2011 10:41 amI installed a HEI dist on my 230 6cyl engine. It's the dist with the coil built into the top. I don't know where it came from (ebay?) as it was in a box of new parts to install when I bought this van. I installed the dist, new plug wires, and new plugs all at the same time. I ran a new 12 gauge fused wire from the fuse panel for power to it.
The engine starts and runs great with the vacuum not connected...timing is at about 8 degrees warm idle (600 RPM's). The timing advances while increasing the RPM's to a point I can no longer see it under the water pump pulley. This is with the vacuum pod on the dist plugged or not, and the vacuum hose plugged.
When I hook up the vacuum hose to the dist the engine starts and idles fine, but give it any gas and it backfires, stumbles and dies. The timing mark is at 8 degrees at idle still, but once I give it ANY throttle it's gone. It runs as if the timing was advancing way too quick and too much. The vacuum hose has no vacuum at idle and increases with RPM's.
The carb is a "new" remanufactured by Holley Rochestor monojet with elect choke. The engine is stock with no cam modifications.
If I drive down the road and try and plug in the vacuum hose it sounds like I have a M60 in the back and it blows all the plugs off the carb and the hose to the PCV valve.
Has anyone else ran into this? Anyone have some suggests to try? Am I hurting anything driving it without the vacuum hose connected?
