what happens when valve float occurs
I am just wondering if the motor makes any kind of wierd noises like sounding like it is hitting off the rev limiter. Just wondering if this might be happening with my car. Sometimes it seems like it is hitting the limiter at 6400-6500 but the limiter is actually set at 6750. Could i be getting valve float of could my stock tach just be off that much?

My tach, depending where you are on the tach, is from 300 to 700 R.P.M. off. In my case the stock tach is showing more R.P.M.'s than are actually being turned

ok, thanks fellas, that is what i was thinking, and i believe you are right. I just didn't know if it was common for them to be off up to 300 rpms. I figured it wasn't exactly accurate, but didn't know they could be that bad off.

Ya the stock tach is on the money if you rev it slow, on a free rev I'm hitting my 6500 rpm shift light when my stock tach is at like 4000 rpm's. Opps.... Just a little mistake by GM. Get a gauge shift light, it goes right in a gauge pillor and has a digital tach built in. Auto meter and SW make them, there great.

I had valve float happen last summer on my car, torquer cam and prc duals. Springs had between 15 and 20k miles of abuse on them. I went to race a buddy, and the car wouldn't pull past 5500, it just flattened out. Tried everything little first, cleaning sensors, changing air filter, as it was filthy, thought maybe I got bad gas or something. I bought a new set of valve springs and took the car out and it pulled its *** off.
