Quad carb setup information help
With a 262 @ 050 cam, you are going to need a LOT more than 22* at idle for best idle quality/performance/off idle tip in. More like 40-50*. The large plenum volume of a TR intake is another reason that more timing is needed.
Don't believe me? Do this 5 min test: engine idling at about 22*, rotate dist slowly to advance timing. Idle rpm will increase & idle will be smoother. Both are indicators of more efficient use of the A/F mixture [ rpm increase is actually the engine making more HP ].
