The Riley 2 port was a good ‘civil’ piece. Riley sold his 4 ports with matched sequentially numbered dual 2” side drafts …to his racing friends for serious racing. These matched sets were the race winners ! All parts matched/assembled by George himself.
I had such a ready to run 4 port set , on my shelf , for that someday special build for myself… until my health went to heck two yrs ago. The setup went to an original racer to finish his restoration… 10K. These old race cars had a nasty habit of burning engine to ground. This was contribution to replace that. Heart breaker. The guy( previous owner) died of old age. Hope it is not jinxed… but new owner is a yute.
