Northstar, 4L60 combo

[Joe Boucher]

One more comment about this mechanical stuff.  The tranny's out of S-10's were bolted to 4 and 6 cylinder engines.  The Northstar puts out a
bunch more torque then those engines.

Think about it.

If you are going to go that route, you might want to set aside some money for an internal upgrade.  Or for the inevitable rebuild.
