Hi everyone,

I have a 1990 chevy caprice with 5.7L 350 engine. I wanted to swap it out for a 454 big block. I wanted to know what adjustments do I need to make if I want to get a 454 on my car?

I would really appreciate it anyone can help me with this.

thanks

WOW! "Adjustments".....I won't call it adjustments.....how about REPLACE EVERYTHING!! :>)
You're taking on QUITE a project.....
The entire big block drive train should be installed, not just the motor. Then there's motor mounts, trans mount and cross member, drive shaft, differential, suspension upgrades....wow....I'm getting tired just typing all of this....LOL!
You gotta remember....modifying is a balancing act.....when you take away a small block V-8 and install a BIG BLOCK V-8, what is it going to do to the rest of the drivetrain?
One thing you might consider.....find a early to mid 70's Caprice. They were opinioned with the 454 so you'd have everything you'd need. Or if you go back even farther, Chevy made Caprice's and Impala's with 396's and 427's!! Now THAT'S a drivetrain!!

I know "bigger is always better", but the things you can do with a Chevy small block....I know....I own one. I have a friend that spent BIG bucks putting together a 68 Camaro SS 396, 4spd. He smiled at me and said," You're gonna need a roadmap to keep up with me!" I smiled back and told him, "It's not always what's under the hood that matters as much as what's between you're legs!" Nope....he's NEVER beat me! God knows he tries. Have fun with the small block that you have....or find a B-body with a big block already there.....whatever you do...HAVE FUN!

Agreed....I try never to tell anyone not to do something.......if it's too much of a project, they'll find out for themselves....
