Former Pontiac Motorsports Manager John Callies: Epic Golden Era NASCAR Stories & Garage Tour!

What happens here

The interview transitions to John's office, where he showcases various prototype engine components and tools displayed in glass cabinets. He demonstrates a classic oil ring and highlights a project involving a two-wheel fuel lifter designed to withstand extreme cylinder pressures in Top Fuel dragsters. He explains the challenge of achieving proper valve opening against high pressures. He also displays a vintage piston with narrow rings from 1982, noting its advanced design for its time. He also shows a set of weight samples in magnesium, aluminum, and iron, illustrating the significant weight differences between the materials for the same volume.

Goal: Illustrate specific engine innovations and engineering challenges.

Tools and materials

  • Aluminum Weight Sample — Demonstrating the weight of aluminum
  • Classic Oil Ring — Demonstrating friction reduction in pistons
  • Iron Weight Sample — Demonstrating the weight of iron
  • Magnesium Weight Sample — Demonstrating the lightness of magnesium
  • Two-Wheel Fuel Lifter — Addressing high cylinder pressures in racing engines
  • Vintage Narrow-Ring Piston — Illustrating advanced piston design for its era

you feel that Oldsmobile and Chevy and Buick teams could put your heads on there and then go beat Pontiacs with that I mean and to me I just was happy they were you know we my intent was make a head that didn't look like a sprinkler system obviously we've made better power but it to me I was just happy to get heads out there it's really for the racing Community to have better stuff that's what started when your boss is happy that you did that for the whole GM Fleet that was never a question I mean they were looking just what we were doing because in Pro Stock we changed again everything in Pro Stock where they had then I did a V6 head so I did a four-cylinder V6 V8 and small block and big block and then in the in like the Pro Stock head we had about five versions over the the years things just changed but uh yeah JV just easy person to work with and the difference was I was probably the only one in GM that could write a purchase order and then sign to get it paid which was totally illegal but somehow he made it work Ed and so that was a riot you know so anyway just a lot it was the one thing I felt is the aftermarket if GM what we were supposed to do is we'd own all the tooling an aftermarket person doesn't want us to own their tooling so I would say okay I'm going to buy five prototype heads well that would be the cost of the tooling so they own the tooling they can do what they want with it you know and so that's how we got so many parts built on the outside because I work with the aftermarket making it easy for them and also at GM at the time a normal pay might be 60 or 90 days all my guys got paid in 30 days because I was okaying it you know so you're working all ends to try and make it work Ed so you had to be a pretty busy guy in there in the late 80s early 90s at Pontiac because you had all the NASCAR stuff and big names you know Rusty and Richard Petty and all that the Penske guys and all that but then you also had all the drag racing stuff too right I mean then we had boat racing and we had road racing so you know you had it was just non-stop in other words my average year was probably 250 days gone in a year wow you know and that's but you know who gets to go and do all this stuff very few people you know and and sure it caused some some problems but the other side is you've got to experience nobody else can get because looking at each type of racing gave you information and what Nascar was doing may not work in road racing or drag racing but…
