The Stovebolt Site Forums The Shop Area Engine Shop Help build a 292 I6 for towing

I would guess that the 4L80 and stock torque converter for that 86 K30/6.5 would be pretty good with the 292. The 6.5 turbo Detroit was not an extremely high RPM motor, it made really good torque in the low RPM range so the TC should be fine. The K30 would have 4.10 axles as stock or an option was 4.56'S. If I were putting that engine together, I would call Comp Cams and speak with an advisor, give them the specs and expectations, they will advise the cam grind.
