Chevy 366 cu.in. truck engine GOVERNOR

[herkyhawki]

366 cubic inch (6.0L) big block truck engine in 1982 school bus.
I have electrical mess with burnt wires that connect to governor control module (Rev limiter). I think it senses RPM and then cuts off power to the coil when RPM is too high.
Need help finding replacement governor module.
Or Is there a universl module that I could wire in and dial in my rpm limit point?
What would be the RPM limit for this engine?
Right now I wired a separate wire from battery to coil to get it home, but I realy don't want to blow this motor from over-reving.

Don't worry, you won't rev it high enough to hurt it...

The 600 CFM Holley carb won't flow enough air/fuel. The stroke is 3.75", with the same rod as 396, 427 and 454. It has the same steel crank as 396 and 427. It can withstand 7,000 RPM for an extended period. I doubt the cam or induction system can supply enough air/fuel to get it past 6,000.

I wish I could help you as to where to find the parts you need, aside from recommending your local Chevy dealer. Best of luck.

I have a complete, spare governed Holley from a 1978 366T dump truck, Dana two-seed axle, etc. That model used oil pressure to balance the secondary vacuum. I retrofit a plain Holley 4160 in its place and it has been running fine since. Over-revving is not an issue, since the stock valve train (specifically, the springs) act as a governor all by themselves. The Mk IV valves under the stock 85# springs tend to float at about 4,500-4,700 RPM anyway. The speedometer also has an "Overspeed" warning lamp to tell the driver to back out of it.
