I met Roland and one of his partners in the NHOA at that time in the mid 1970s is what I remember at the Spring Fling car show and swap meet in San Fernando, CA. We talked about hemi motors for a little while and then he went about looking for parts.
He was putting a 1966 or 1967 B body together with a 426 street hemi motor together for NHRA stock class racing , I saw him at one or two Division 7races and several more times at the Fall and Spring Fling meets at Woodley park and I heard later he had moved back east.
RIP, my fellow Mopar racer Brother
