Hello, new to the forum and gmt400 platform. just recently swapped a 350 into my 98 that originally had a 5.0, but spun a main bearing. Will my pcm from the 305 be just fine running the 5.7, or should i swap pcms as well? The doner vehicle is a 99 suburban, and I was told that it would run just fine but wanted to confirm from someone who has done it before. Thank you!
