max rev setting chevy350

[Cobra power]

not sure if this question can be answered without supplying losts of details on my engine, but for now a ballpark figure would help.

About to install an ignition control unit, with a rev. limiter function. What is a sensible setting for a chevy350?

Thanks Patrick

Not what you wanted to hear, but is it bog srandard or beefed up. If its bog standard you should be limiting it to around 5500 RPM occasional. If it is balanced and had decent fixings then 5750 should be your limit. If you are using aftermarket uprated rods etc then depending on the product, safe rev limits vary, but most decent aftermarket (NOT BRAND REPLACEMENT AS STANDARD) will see 6000 RPM again as long as you have decent fixings, cxarried out stress relief and had the rotating assembly professionaly balanced.

Even if you have an engine thats components can take high RPM remember your Flywheel quality comes into play at anything above 6000 RPM (if you want to keep your legs).

All the best
Mike

Judging by the terminology, you have a recon standard bottom end, otherwise I think they would have made more of the description. The top end allows better breathing and timing for performance.

If they have done a good job with balancing etc, I still believe you should be limiting yourself to 5750. Depending on your cam with the inlet etc you would not be benefiting much by extending this anyway.

High performance HEI ? I only know the standard HEI distributor which has its own issues above around 5800 RPM anyway - dont know whether it was down to Spark scatter or not, although I believe that there is a kit which can solve this

All the best.
