Transmission fluid flushes on TH350 automatics should be performed every 24,000 miles, accompanied by a fresh filter and pan gasket replacement.
Lubricating chassis grease fittings across ball joints, tie-rod ends, and universal joints during every oil change prevents expensive steering linkage failures.
Cleaning and adjusting the vacuum advance on HEI distributors ensures optimal ignition timing and maximum fuel economy.
Overcoming Common DIY Restoration Mistakes
One frequent DIY error involves improper Rochester Quadrajet carburetor tuning using incorrect vacuum ports.
Mechanics often mistake ported vacuum for manifold vacuum, leading to rough engine idling and hesitation under load.
Another common mistake is ignoring degraded firewall grounding straps, which causes erratic instrument gauge readings and dim lighting.
Few things are more frustrating than spending hours troubleshooting electrical gremlins caused by a single corroded ground wire.
When replacing body panels, failing to shim bed mounts and cab bushings leads to misaligned body side chrome trim lines.
