1st drive.it needs some work

[7ft stew]

i got the blazer to start.it sounds like a race car but thats only because it has straight pipes only(no mufflers).the exhaust exits in the middle so with the tailgate window stuck down for now im getting alot of fumes.it had trouble idleing.i believe it could use a tuneup and some carb work.oh yeah,the pulley on the power steering pump is bent.i really need to find out what year the motor is so i can start getting the parts it needs.you guys have any idea where i would find the stamp on the motor to identify year and size?thanks,stew
