  • Bus Engine

    There was an interesting article in NSSN about Roger Rager and his bus engined Indy Car.

    Seems he chose the bus engine because the bus went thru many starts and stops. Thus relieving the stresses in the engine.

    That was the story back when he ran. Whether it's true or not who knows.

      The stress relieving has to do with heat cycles. In other words, MANY heat up - cool down cycles. Start-stop really isn't it. It has to do with running and not running...

          Was it a GM block? Most of the school buses I remember from back then were International Harvesters. The rules of the time allowed 355 cu. in.(?) so a big-block wouldn't have worked. Wonder how much HP it made. He led a lap! (Under a caution/pit stop shuffle.) Too bad driver error in a tough spot took him out.

            I remember reading about it in Open Wheel 30+ years ago.

            They weren't really shouting from the rooftops that their Indy entry was running a school bus motor.

            It just came up in conversation when asked about the spare engine they had to use. I guess the good motor broke.

            After that it was a big human interest story around the track.

            The bus company even kicked in some sponsorship for the teams' 500 effort once the story grew legs

              That was my recollection as well.

                After looking a bit it had to be a destroked 366 big block truck and bus engine. There seems to be no alternative.

                  That is what I meant, just didn't use the right words.

                    It was a Chevrolet. I remember an image of the car with the words "Chevrolet-built in America by Americans" on the engine cover. Also, IIRC the school bus sponsor was Superior School Bus.

                    Rager was headed for a top 10 finish before Jim MacElreath spun in front of him. Even the radio announcers were crushed when that happened.

                      I was a Chevy I looked it up. They got three of them and used what they thought was the best block. But no where can I find them saying what engine it was.

                      I could also have been a 454 from a van chassis School bus.

                        It was a 350 small block.515sNNFK50L.jpg

                          Then this whole School bus thing is overblown. It was probably a scholl bus painted Chevy Van. And to say they took three engines from the junkyard could mean the the other could havv come from a step van or a small box van. Because he says they were looking for a commercially used engine. I found an AP article from 1986 talking about it.

                            Here is a pic of a 70's Superior bus, that could have had a 350. A School bus for sure but not the Image that we were all lead to believe.

                              Because all the big teams used engines out of a short bus at Indy back then.
