I like your combo as well. It has Mopar heads on it. It made more than that. Also on a SAE calibrated dyno. Not at someone's single cell dyno in their shop that they can almost make any horse power number on that the customer wants. (Not saying yours did). I know how it is in the industry. Mine only picked up 11 h.p. with the vac pump but I went with old school trusty 1/16, 1/16, 3/16 rings since it is a street car. Didn't want ring issues with thinner/better and much more expensive rings with putting so many miles on it. I built it. The whole car is home built with the help of some buddies.
