350

I have a '97 Tahoe I'm looking to swap the 350 out with a 454 out of a '95. I know it's possible but my biggest concern is the 454 being obd1 and my Tahoe being obd2. Any help would be greatly appreciated. Thanks in advance.

Ok so a blew a hole through my 350 vortec in my 98 tahoe so thats a done deal. Thing is my uncle has a built 305 in working condition that he pulled out his iroc its not a tbi. And I was told its a direct swap I wud jus have to carry over my intake I wanna know if thats all I have to do or do I...
