70 L78 Nova T400 Question

[JoeG]

Bill Pritchard,
It was a factory fail-safe in the M40 to shift out if you exceeded tolerant engine rpm limits---The reason I say this is because, during a run, back when, both cars were side by side headers open, couldn't hear my engine revs--I was just watching my hood-tach --car was approaching 6600rpm's so I thought[really around 7000rpm's], and then shifted to 2nd by itself--after having trans. checked out it was determined the hood-mounted tach was giving a false rpm reading of 400rpm's ,had the hood mounted tach fixed, installed a Sun 802 the problem was solved.---JoeG'---MY handle did not move, but I had a tight grip on it.--

I had a 67 Impala small block with a T400. The first time I really let the rpm's climb, it changed from first to second unassisted, with the shifter still in first. The shifter didnt move but it did change. That was the first car I ever has that would spin the tires in second gear!! [img]/ubbthreads/images/graemlins/[/img] Kevin
