A few days ago I posted about my truck not starting right after I finished a mud recovery down the road. Well it took me about 10 minutes to figure out what was wrong. Situation- 8 month old GM Performane Parts Crate Motor installed all new components to include distributor. High performance model distributor. Problem- Truck wasn't starting due to no fire after a mud recovery run down the road from the house. Fix, Replace distributor cap and rotor button and coil. Question- Before the truck had a really rough idle almost like a performance hot rods with a performance cam. I replaced the above mentioned items with parts from my old motor that I pulled out to put in the crate motor. After putting all old elements on it has tamed my engine down. Idles just as smooth as a brand new car and very quiet if I might add especially with dual 40 series Flowmasters. What would cause that to happen with just changing those compponents? I did not adjust timing while I was in there but still don't understand why it happened. Any way the Stomper is back into commission so she will get another test drive tomorrow in the same mud pit on my way home from work. Glad I have a winch now so I can go alone.
