@aircooled posted:A long tome ago now at the OCIR drag strip out here they had a competitive event and these two guys did it in 3 minutes 29 seconds. The car was parked 15 feet from the starting line. The competitors had to carry their floor jack, tools and jack stands from the starting line to the car, jack it up, remove the engine, pull the engine back on the jack to the starting line, then back to the car, install the engine, lower the car, start it up and back the car back over the starting line.......in 3 m 29 s ! If I hadn't been there I would not believe it. I think others beat that time later .. That's the kind of guys you want in your shop on "flat rate" !.......Bruce
I bought an engine from a guy in Las Vegas that had two so he could run in both <2L< classes and he'd swap them out between runs.
I guess he grew tired if it because he sold me his 1835 because his wife wanted it out of "her" garage.

Three minutes is a lifetime compared to 3 seconds.
How about RBR rebuilding Max's car in 15 minutes after he binned it during the warmup two weeks ago?
