HERZOG RACING ENGINES

Working on a dual overhead cam 4 valve per cylinder hemi and I was told it won't work you can't do that. So, I wanted to prime the oiling system of a 2.2 Cobalt engine which has a crank driven oil pump. I was told there is no way to spin the pump without turning the crankshaft so the only way to prime the system is with a pressure pot.... I purchased a piece of plastic for $9 and turned up a priming tool on the lathe to spin the pump. Wella in about an hour using half the material. I can prime a 2.2 the right way.

LISTEN UP .... I am here to help you make educated decisions about your transmission options. If you call and want to discuss your transmission needs, I know doubt, will ask you about your vehicle and what your wanting to accomplish. If I ask what the weight of the car and tire size is I am looking for a correct answer not you him hawing around the question and continually saying it's 750 hp. Big difference from a 1500 lb car as compared to a 6000 lb 4x4 truck. So hanging up on me because you don't want to disclose info, I can't help you. If you can't or won't be truthful I really don't want your business. You people that "think" you know everything need to build them on your own. No need to argue with or call me. Those of you that need or care to take advice from someone of 50 + years experience I am here to help. 636-456-9006 Thanks
