Has anyone out there messed with the 4.2L I6 from GM? I aquired one to put in my 70 Chevelle. It looks like the biggest problem is going to be the trans as this motor doesn't use a std. chevy V8 bellhousing bolt pattern. I don't want to use a auto and am looking for a 5 or 6 speed to bolt up. The one out of the Chevy Colorado should fit but after turbocharging this engine should be 300-400HP and I doubt that trans will take it. Any ideas? Thanks.
