It just seemed to me that I always see alot of bigblocks with the 6pk setup and not many smallblocks. I know more bigblock models came with the 6pk in the B-bodies then the smallblocks came in. The 340 six pack was only in the 70 E-bodies or the 1971 Mr Norm Demon. But I see many cloned bigblock cars using them. Just seems since Mopar had the smallblock and bigblock 6pk cars that you would see more on the smallblock then you do. Ron
