repalce a TBI 350 with TBE 454? Any issues?

Does anyone know if it would be a plug and play swap (except motor mounts) to put a TBI 454 in a burb with a TBI 350? or are there differences in fuel line size etc?

thanks

There are a few electronic differences, you'd need the 454's computer and I believe theres a few extra pigtails and sensors. You also need a new transmission because the big block wont fit the small block belhousing.

thanks TB! Wow, a new tranny? I've never seen tranny's listed by small block or big block bellhousing bolt pattern. I've only seen Chevy or BOP.

Looks like it would be a lot easier to keep it a 350.
