Default Cam Driveability question

I recently redid the entire top end in my lt1 6spd. LE2 package, heads,cam intake, injectors, 1.6rr, hd wp.

Cam specs 228/236 .592/.592 110lsa set to idle at about 800-850rpm.

The car has some wicked power, especially up top. However it seems to be really jumpy while crusing at around 1700rpm. Almost feels like its miss firing, but i severly doubt it is. Ive had it dyno tuned, somewhat. Car didnt want to cooperate properly, so its gotten much better then the mail order tune. 32* timing roughly, no knock.

Basically what im asking is, what should i expect? Ive never driven a cammed car so this is more or less for my knowledge. Thanks

Sounds like cam surge, which is completely normal. You can have it tuned out but it takes a good tuner and some time to resolve.

tuning normally takes more than one trip to the dyno or tuner.

If you could log whats going on it may be easier for someone to tune it properly.

yeah it happens. mine is 242/248 .608/.612 and will jump at lower rpm. going to the 4.10 gears helped but it will still lunge at around 1500 rpm, and mine has been tuned.
