See if you can get in touch with Tlowe he just sold me a housing for a 292 with the bypass. He may have another one. Also, FlowKooler makes what is supposedly a high flow pump for a 292. I can't say for certain if is in fact any different then a stock pump because the one I bought is still in the box awaiting my 292's assembly. I think I paid about $100 for the pump if memory serves me correctly. The thing that puzzles me though is when you go on youtube there are videos of 292's running with the correct pump or a 250 pump. Didn't the 292's come with the 250 pumps after 1980 or so?
