408, Small or Big Block? Need EGT Info

Thanks Brooks. I used to be working with a stock motor which everything is different on. I went performance mode and am in a little over my head. I don't mind learning, and the Duster has 2x the hp about, which is great. I guess I will just have to as the Gauge mfger what the normal, hot and too hot readings are. No one seems to know. lol
