RE: [Chevelle-list] Back in the Day / Float the Valves?

A good rev limiter shouldn’t do any harm unless you continually run it against the limit which, I suppose, could foul plugs in time.  The idea is to cut spark to cylinders so the engine won’t rev any higher  I don’t think professional class drag race cars use ‘em, maybe Pro Stock – not sure, but NASCAR sure uses ‘em.   Dale McIntosh 67 El Camino 1967 Chevelle Reference CD now available!

Of course, even if the rev limiter caused some damage, it's probably not as serious as over revving an engine I'm sure.  There's no KABOOM! when you hit a rev limiter.  Just wondering if there might be long term harm.

Nope...it's basically reving the motor past the point where the valve springs can close the valve in time for the next compression or exhaust stroke. It's a "bad thing"...especially if the piston slaps a valve. That's one of the reasons valve seat spring load is important and why you match springs to cam, etc.   Craig E. ----- Original Message ----- From: [EMAIL PROTECTED] To: Chevelle-list@chevelles.net Sent: Thursday, October 13, 2005 1:55 PM Subject: Re: [Chevelle-list] Back in the Day / Float the Valves? Well I am 41, been around cars my whole life and have not heard the term "float the valves"  doesn't sound like a good thing to do, but what is it?  My guess - depressing clutch to shift, but intenially not taking your foot off the gas?   Thank you,   Krister Meister Bloomingdale, IL '66 SS #'s   -----Original Message----- From: Bob Haggard <[EMAIL PROTECTED]> To: The Chevelle Mailing List <Chevelle-list@chevelles.net> Sent: Wed, 12 Oct 2005 21:48:21 -0400 Subject: Re: [Chevelle-list] Back in the Day When I was in the Air Force (66-70) a friend had a red Chevelle SS with 396/350hp.  It was a beautiful car and what I always remember was he liked to shift when the valves would float.  I was amazed that it stayed together since a high school friend had a 63 Impalla (1963) with 409/425hp that would float the valves when he missed a shift and it would usually end up back at the Chevy dealer to replace bent pushrods and other assorted parts.
