I have a fresh 350 with an edelbrock perf rpm cam and 750edel carb. The carb was untouched from previous engine along with the distributor and heads but everything else is new.
My ? is, when I start the car and just sit the car idles good, and the temp stays cool. After I drive it for abit the temp becomes harder to control and the car never idles back down when stopped.
I have messed with the timing many-a-time. It's only helped a bit. I'm thinking since the heads are crappy irons and I'm running 10:1 that somehow when the car is warm there is some kinda of detonation going on to keep it from idling down. I don't hear anything though, and the car runs strong?
any help would be great.
