LT-1 issue

[John Nechiporchik]

After thrashing on this beast all day, checking all the items that were suggested, it appears that going thru the valve train and re-lashing the valves was the primary contributor.
I installed a new cam this winter with the "shimmed" lifters and appears I adjusted them too snug...and 4 valves (2 Ex and 2 In) were extremely over adjusted. So I went thru the system and re- set them all until "0" lash.
Fired it up and idled like a dream....revved it up slowly and with the exception of a slight flat spot around 3000RPM, it revved right up to 7000. I'm thinking (Ed, the tune up)needs to be tweeked for the new components. Tomorrow we'll hook the lap top up and see if we can work on the flat spot.
I'm thinking it's time to make an appointment with the chassis dyno guy to see if we can fine tune this thing.

I hope I'm done on this issue. Thanks to all of you for your ideas and support.

Special thanks to Russ Abrams for the all day text message and phone call support.
