Sprint car motors?

410 ci grenade with the pin out. Years ago our "Open Wheel" division on the 1/3 mile clay was very liberal in the rules department. At least 1 BBC we used to see on a regular basis. Zoomies were not uncommon. The entire valley was tuned into that sweet sound on Saturday nights. 30 winged cars was the "usual" Saturday night show. I just got my first open wheel fix Saturday night for this season. Ironic that the "Horizontally challenged" (Midgets) were qualifying faster than the 360s. Track wasn't up to the horsepower yet, but it came around. There is a winged sprint show at the fairly nearby 5/8 asphalt track that I have just GOT to see this year.
