Thanks for the replies, and for confirming what years/cars the 496858 brkt is originally for. This 301t engine was bought as a parts engine and was already pulled from the car when I got it, so no clue if it was factory or put on after the fact for some reason? But they both look the same condition/age so whatever the reason, its been on there quite awhile.

Ive owned 4 or 5 of these turbo cars and about the same number of 301T engines and did a full subframe off resto of my 81 pacecar, but never paid much attention to the mount brackets or their part #'s. Cant say Ive noticed the 301t engines being tilted, they seem to sit square in the frame visually just like other 2nd gen Firebirds, what was changed was the turbo hood with the offset bulge to clear the offset carb on the turbo plenum.

Maybe this 301t was put in a later 70's-81 A, G or B body car?? Who knows, people did/do strange things with cars sometimes. But at least I know what the odd mount brkt is for so I can list it for sale. Thanks again!
