WoW such hostility oh my! forgive me for misreading, the 15B's are a common engine here, just not many around that aren't still in a running truck unless it got wrecked. They will be showing up in a few years though. If you would read the post(s) Heepeater is in JAPAN! Best time to get a good engine for his Cruiser. If he went back to the States with it and when it did need parts there are plenty of people that could get him what he needs. Have a back up Cruiser whilst you wait on your parts is my sage advice Pactoy's BJ-44 and my other friends BJ-73 (both 5 speeds) don't have any issues with throttle sensitivity at any speed or RPM. Maybe the throttle sensitivity is just your shaky foot from all that built up anger
