Re: ??? about 1991 chevy suburban drivetrain
The block could be two or four bolt, the only positive way to know is pull the pan. If it is four bolt, that is a desirable core worth about $175.00. The one piece seal blocks are fine, no reason not to run them.
Chances are, the crank is cast. However, that also is fine, no problem with running a cast crank. A stock cast crank is worth about $80.00
The heads have no special value except for a stock rebuild. Same for the throttle body injection.
The trans will be a four speed, again, no special value except for a stock rebuild. The trans core is worth about $150.00
