454 vortce in a 350 tbi truck

[chris989]

Hello all,
Could not find a decent post with a conclusion so here is the question.

I have a 350 tbi, 400 turbo, np241 1989 suburban. I have access to a 95 burb with a 454 vortec, 4l80, np241.

1-will the 4l80 bolt to my 241 being a passenger drop vs the driver?
2-will the motor fit considering manifolds and accessories?
3-will it be a computer nightmare?
4-i do not have smog where i live so can some of the emissions come off?
5-in the end is this just not worth it?


the OD is more important to me than the 454. I am fine with the small block but it has 240,000 on it so i thought about changing both.

any advise or a link to a complete thread would be great.
