305 to 350 swap

I don't know much about this stuff that's why I'm asking. I have a 90 rs camero with a 305 TBI. I found a 88 350 TBI truck motor. Is this a good idea/ will it work? will I have to change anything?

Thanks

Injectors, chip, & ESC module off the truck. The rest will drop right in.

You can use the truck ecm if it’s a service number 1227747 . It’s a direct plug and play. It’s not a performance tune but the heads aren’t either.

Haven't made much progress. Still figuring out what to do and what's the best way to go. Actually working on a souped up 350 tpi. Waiting to hear back from the guy.
