400 whp would be realistic with a damn good trans and suspension parts and drive the piss out of it and not have to worry about breaking crap if you do it right the 1st time. Since when is any FWD a dyno queen? Only a few people have over a 500 whp Wbody thats somewhat driveable. 400 whp much more USABLE hp vs. 500+ whp and breaking **** and stuck in the garage hating life.
