I have a 93 TBI full-size Blazer, it's not roller (until I retrofitted it). I think there's a difference between car and truck use motors. It was also 4bolt mains and I think the cars are 2bolt

Yea...like AINTNOHO, its flat tappet. The only 4 bolts came in the HD trucks or Blazers/Suburbans. The light duty trucks got the 2 bolt.
