[Ace in the hole]

yep, sm465 behind a 350. It is a centerforce dual friction clutch but if I remember correctly it is only an 11" clutch. I think it was a #735552 I bought it new from a guy near home here who purchased it and then realized he bought this one with 10 spline and needed the 27? spline. He went out and bought a whole other set up and had this one that had never been used.
