Chevy 350 swap help
 

So I picked up a 355 built motor that puts out like 400 hp. I have a Th350 and I was planning on keeping the stock transfer case. I already plan on doing a 3 in body lift but heard that the oil pan doesn't fit. Would a low profile oil pan fit? Maybe with 2 inch lift from strut spacers? If anyone knows where I can find a custom oil pan that'd fit that would be great because I really don't want to lift the truck. Also what else is needed to support 400hp? Keeping price in mind of course. And while this isn't a racer or something I'd go mud bogging in I'm not the lightest on the peddle.
