Gets hot and stalls out
Seems like everybody missed post #35.......
That is a sizeable cam & will have a rough idle. If the initial timing is still at factory specs of between 4-15* [ 12* is typical ], then not only will the idle be rougher than it needs to be....but the engine will run hotter at idle & low speeds. The idle timing may need to be as much as 45* with that cam.
If the ign timing is still stock, then here is a simple 5 min test: engine idling, loosen the dist clamp & turn the dist slowly CCW; this advances the timing. I have not seen your engine, but I know what will happen: idle rpm will increase & idle will get smoother.
This happens because the additional timing makes the engine more efficient & it runs cooler.
