What’s the optimal freeway rpm for a small block Chevy?
Some of those guys turn nearly 4k going down the highway. Not to be a post hog, but 3.08s and OD is right on the edge of acceptable IMO. GM loved to do that combo on G bodies, and they just don’t use OD unless it’s on clear highway, and even then it’s kicking out the converter for everything.

The RPM goes to 0 and the engine shuts off. This only happens when travelling at low speeds (e.g. slowly accelerating from a stop, braking, moving in stop and go traffic) This NEVER happens when I’m travelling above 10 mph (e.g. if I’m coasting at 40 and let my foot off the gas, the RPM can go to 500 RPM but it will never stall in this case).
