I'm shooting for about 425-450hp.The 32" tires were for ground clearance,only.Losing an inch or so on tire height shouldn't affect clearance or gearing much either way.The car is set up for a 350.I think a glide/350 will just interchange(output yoke,case lentgh,mount location),am I right in this?I've always had 4 speeds and 400s,so thyis is all unfamiliar to me.Thanks for all the info everyone.And yes ,I am gonna footbrake it.What's nostalgic about a transbrake :?
