Fr. Frank,
Thanks for the reply. I'm an auto mechanic which is why I like inboards and I/Os better than outboards but I'm not real familiar with volvos. I do know that I looked up the price for an exhaust/intake manifold which is dealer-only and it was like $2500! I'm assuming these should be replaced every 5-6 years like the ones on a v-6 or v-8? I guess when the manifold goes I'd just swap to a GM inline 4 like you suggested - It'd be cheaper and only have one carb to deal with
