So re-checked everything today, reset timing even checked for timing chain play (pretty sure it was less than 10 degrees) and car still wouldn't run right. Then I replaced a connection on a wire leading to the coil, and it fired right up and ran better than it has for years after some fine tuning on the Holly. So after about a 10 minute drive, pull into the garage, start it a few more times to double-check - and then after 15 minutes it barely starts and runs like crap ( like a weak ignition I'm thinking ). The distributors been checked (MSD pro billet) coil, cap and rotor, plugs and wires all new. So what would cause this (what seems like an intermittent failure)?
If the timing chain was loose, it wouldn't have run great minutes previous, right?
Could it be a wiring issue that I'm going to have to dig deeper to find?
I've included it video of it running, but the sound quality is not too good, but if you listen to the whole thing you can kind of hear I would seems to be missing a few cylinders, and dying whenever you give it some gas.
Thanks for any light anyone can shed.
