I suppose it wouldn't matter if you had even 800hp. if you only plan to use car as a 'daily driver'. I doubt you would be utilizing anything close to your anticipated hp rating just by putting around town and to the occasional cruises. Of course there would be many internal concerns should you decide to take it to the track and initiate a 'brake stand'. Yes, please tell us more of what you have under the hood (and between the rear wheels). :stirthepot:I will just be driving My Valiant around town and to car shows. I have a storck 727 tranny and I was woundering if it can handle 500 HP?
