Lance Johnson Posted October 9, 2018 Report Share Posted October 9, 2018 I just installed a remanufactured 1967 Cadillac 429 engine that's been sitting for about two years, it crank well without the spark plugs but when I put the plug back in its tight, it turns very slow if at all. Any Suggestions on how I can get my motor running? Link to comment Share on other sites More sharing options...
rockfangd Posted October 10, 2018 Report Share Posted October 10, 2018 Could the starter be bad? Maybe it cannot handle the compression. Where did it come from? Not a bad idea to drop some oil into the plugholes and crank it over a little bit to help the oil to the top end.

Lance Johnson Posted October 10, 2018 Author Report Share Posted October 10, 2018 The starter is turning it pretty good without the plug. Link to comment Share on other sites More sharing options...
Logan Posted October 10, 2018 Report Share Posted October 10, 2018 If the ignition timing is off it can do that.

Lance Johnson Posted October 10, 2018 Author Report Share Posted October 10, 2018 Thanks! we're setting the timing today, hope that the problem Link to comment Share on other sites More sharing options...
Logan Posted October 10, 2018 Report Share Posted October 10, 2018 There is a range of timing adjustment for the distributor. That range is often limited because of the vacuum advance and nearby obstructions. (intake manifold, firewall etc) If the distributor does not get 'timed' correctly with the engine.... within that range....you can get slow cranks. So you may have to pull it out several times.....and mess with the drive gear slot... to get it timed in correctly with the engine. You really cant just drop the distributor in and crank it up. You do have to fuss with them a little to get it set up right.

Lance Johnson Posted October 16, 2018 Author Report Share Posted October 16, 2018 Not yet, the professional wanted to go inside the motor, l don't really want to get that drastic yet. Any ideas? Link to comment Share on other sites More sharing options...
BodybyFisher Posted October 16, 2018 Report Share Posted October 16, 2018 I don't want to reinvent the wheel here, or assume you have not done this but its pretty easy. Just bring the engine to TDC, #1 on the compression stroke, ZERO on the timing mark, install the distributor so that the pointer on the rotor is EXACTLY at the #1 terminal on the cap. That should be enough to get you started. Where are you located?

Logan Posted October 19, 2018 Report Share Posted October 19, 2018 Curious.....I think Rockfangd asked earlier...... What exactly is this 'reman' engine? Was it in a crate or anything like that? Where did it come from? Does it look fresh? Has it ever been installed in a car? What was wrong with the original engine? Thinking maybe timing chain marks off or wiped out cam lobes...
