Is it also longer in length than the 235? Thanks. | | | | | Joined: Dec 2008 Posts: 64 Wrench Fetcher | | Wrench Fetcher Joined: Dec 2008 Posts: 64 | 235 is taller than 250; makes a little change to the exhaust pipe connection & changes fan location @ radiator. As well I think its a little longer; witch will also change fan to radiator relationship. (Anybody feel free to correct me here if I'm wrong) you will also need a different bellhousing to match the new engine up with your transmission.

It's true. I really don't do anything but browse the Internet looking for trouble... | | | | | Joined: Feb 2010 Posts: 19 Apprentice | | Apprentice Joined: Feb 2010 Posts: 19 | Sorry, its to go in my 51 chevy deluxe car , it currently has a 3 speed tranny but I would like to upgrade at the same time to a T-5 5 speed from a S10. | | | | | Joined: Oct 2003 Posts: 5,152 Cruising in the Passing Lane | | Cruising in the Passing Lane Joined: Oct 2003 Posts: 5,152 | That makes it easier. Someone makes V-8 mounts for that car, wish I could remember who. I'd buy the V-8 mounts and a transmission cross member and use whatever bell housing came with the motor and go that route.
The 230/250 will mount just like a Chevy V-8. The 292 is different.

Both bellhousings are about 6 1/2" deep. Positioning of the assembly front/rear with custom motor mounts will be necessary due to the differences in mounting hardware.
