[66-PMD-GMC]

I'll throw rocks at the hornets nest too.
Pro Street is a term that sets a vehicle apart from standard issue modified street cars.
What is it that makes that difference? The street version of a "Pro Stock" is what it means.
I have been building fat tired "Pro Street" rides since the mid 70's and until recently, the last ten years about, pro street meant tubbed, mini tubbed and a HIGHLY modified rear diff. and suspension. If all you can stuff under the rear of the ride is slightly over-sized wheels/tires then it ain't a "Pro Street". Motor size means nothing.
Like my 63 GMC with 19 inch wide Mickeys out back... a tried and true PROSTREET.
