modding 97 WS6
The long tubes will provide a great increase in power, between 20-30rwhp gain with a tune iirc. Im sure others will chime in with personal testimonials/more exact numbers
You should definitely put down more than 230-250. If you do, then something is majorly wrong.

FWIW, I was pulling a good 2-4mph on most non WS6/Firehawk cars. Stock for stock. Once modded, it narrows considerably.
I made several pulls both times and they were consistent with each other.
It had 3.73's, CE rear drag shocks on street setting, worn 275/40/17 MT ET Street Radials, 3600 stall, Ebay LT's, ORY, and slp LM2 exhaust, untuned.
You should have no problem putting a few cars on your friend. I know I sure as hell didn't with all of the 3V GT's I ran into out here. Especially from a dig
This is how GM got away with jumping from 275, to 285, to 305 with basically identical motors from 93-97. No way in hell adding a second cat was worth 10hp...but it allowed them to show progression on paper while they stalled until the LS was ready.
