I am inclined to agree with the Edelbrock heads. I found this interesting info about Edelbrock “inventing” the use of nitromethane in Ford 60 midget racing to beat the more powerful Offenhauser powered cars. Seems it was always the cheaters that moved racing technology forward. Those were great times that made the excitement and intrigue of all forms of racing grow. Every kid with an old car was trying to figure how to make more power from his engine. This article is bringing great memories to me this morning. We had one family in particular that was very good in drag racing. I was able to hang around different “stables” (Kube) as horsepower was talked and created! Heck, I’m getting revved up right now!!!!! Big smile on my old puss!
