Tubs,
Bet that cap would be the same for the 272, 292, & 312 the T-bird mtr. Maybe a 58 big block 332, early 390 block. Remember those??? I had a 57 Ranch station wagon, the two door version. Put a 1965 Mercury engine 390, trans & pumpkin even fit the axle splines. Stopped for a school bus & was rear ended. It was totaled……Now I am a old guy like the one who hit me. It was a fun build though!!!
