5 = 5th
5 = 1955

| | | | | Joined: Sep 2001 Posts: 29,269 Bubba - Curmudgeon | | Bubba - Curmudgeon Joined: Sep 2001 Posts: 29,269 | Looks like a late 1955 engine 235 that was put in a 1956 car?
All 1956 and later 235 engines had hydraulic lifters. I wonder if the late 1955 car engine put in a 1956 car had mechanical lifters (only Powerglide-equipped 1955 235 car engines had hydraulic lifters).
| | | | | Joined: Dec 2005 Posts: 2,557 'Bolter | | 'Bolter Joined: Dec 2005 Posts: 2,557 | Tim,I will be pulling the side cover to check to what lifters it has.
Thanks,Tim
