Stock LT1 dyno number?
what do most stock LT1's run on the dyno with the a4? anyone have any thoughts what i can get out of mine with a magnaflow exhaust 160 stat, and hypertech programmer? I plan on doing a vortex ram air intake for the spring with an upgraded maf sensor, any other suggestions for mods that ill notice a gain on the dyno?

About 280 or so hp.the exaust lost you most of your power.
Bee hive valve springs LS1 from CompCams 1.6 roller rockers and the hypertech tuning should get back in the 300 hp or more area.

Theres a thread about the LT1 being underrated on this page, read that.

A stock LT1 with an auto will dyno between 250 and 260 rear wheel. A 6-spd usually falls right between 260-270.
As for the mods that you've done, it'll still dyno between 250 and 260. Any exhaust modifications on a stocker are very small if any and the hypertech programmer has been dyno proven to give up horsepower in back to back dyno runs. Maybe any gain you get from the exhaust will offset what you give up from the programmer.
I know it's probably not what you want to hear but it's the truth.
