Loopers with expansion chambers

[Heliarc]

Just thought I'd upload this picture of a C Looper from Region 3 back in the late 70's. There may have been a number of others, but I only ever saw one other Looper like that. A guy from Vermont showed up in 1976 at a Region 3 race at Norristown, PA with an A looper with expansion chambers. There was a full field of A's that weekend and he finished in the top four with it. Sorry the pic isn't that good of the engine. The original picture was supposed to be of the guy standing there, not the engine. That is the only closeup picture of that particular engine that I know of. The C Looper was owned by a guy from Pottstown, PA
