Yeah, not too bad, but still not something that the everyday garage mechanic would want to undertake.
I'm under the impression that the trannies can be swapped with little or no problems. I know for a fact that clutch and flywheels are direct replacements. kaoskustoms lives here in Longmont with me, and he said he had a slight problem with swapping an F-series auto tranny onto an H23 block. Chad, can you shed some light on what happened?
