This question was bandied around on LS1 tech and the responses ran into the thousands. Since the term significant was chosen I think the Estes car stands alone. Had it not been built,you might have seen about five consecutive years of Manufacturers championships for ford in the T/A series. Five decades of the RPO..how many others lasted more than one?. From a valuation standpoint which would fetch more at say BJ,that(or any) ZL1 or the Estes car?. Don't get me wrong I love the ZL1's but all 69 don't add up to the influence that vert had in changing chevy history in both production and racing.
