I have just acquired a 1997 S-10 blazer for my daughter to drive with the exception that i have to put the motor back together with little if any bolts and no pictures or idea of what all goes where on this little thing. this has a 4.3 litre v6 in it and i have gotten new motor mounts and the block is mounted but i have no idea of which head goes on which siide of the motor. This motor is out of a 1993 S-10 and only had 83,000 miles on it but again i didn't take it apart and i don't see anything on either head that indicates which side which head goes on. One head has two sensors mounted on it the other head has none. Any help would be greatly appreciated and if anyone has a 94 - 2002 blazer that is wrecked that they may be willing to sell bolts or parts off of please let me know they are getting hard to find parts for any more.
