well i have a problem. They drop the motor when they were trying to put it on the truck. The tranny bell housing is cracked, and the */c has some damage. But the motor cv axles and other things are fine. let say i got the motor for a deal i could not turn down. I'm thinking about just dropping a N/a intake on it now :(

If you decide to do that, you should be just fine. There were no compression changes between the L27 and S1 L67...only the internals were different. You may want to consider porting and polishing the LIM though in the interim.

If memory serves, you can use your existing accessory drive on the L67 when its in NA form, but you must revert back to the L67 accessory drive when you go back to boost.

EDIT: Above statement did not sound right. You will need to use the LN3 accessory drive on the L67 when in NA mode.

Hmmm.....I don't think so. The L27/S1L27 is a direct decendant of the LN3. If you use your current intake manifold, and ECM, you should have no issues at all with running that motor as an NA.
