I was just reading the "My first Blazer" post below from thatK30guy and have a question now. I'm just finishing up replacing the 305 with a 350 in my 84K5. It sounds like I most likely have the 3.73 gear ratio. How's that going to work with the 350. We added an RV cam to the 350 to help with the pullling power. What's your thoughts?
