ATI-917781
a post in a forum just reminded me to update this.Well as i had said,it fit perfectly,looks great,and as far as i can tell it's doing a fine job,it is handling 461 at the crank,for a 383 low rpm top end motor-quits making HP @ 5800 RPMs,but sure gets there quick lol. So I see no reason to give this anything but perfect across the board,the right part for the right application,if your motor falls w/in its specs-dont hesitate,just buy it. ...read more
