I can't really think of many pros and cons. sell the 350 and buy the 454.

well there's a huge difference in costs. obviously to build a 500 horse big block is going to cost min $4000 if you find good deals, which means most likely costs more (assuming you are using new parts). additionally, you have to consider any tranny and drivetrain upgrades you will have to make (very likely). High, streetable horsepower is easily capable by stroking a 350 (400-450hp easy). good stroker kit: ~$2500 + whatever misc expenses you'll have.

Essentially, you are looking at a $5000 project vs. a $2800 project (obvious plus a big difference in time/elbow grease). Sounds like the 350 is a good starting base already since it is recently built. I would stick with it.... you goal is more more easily achieved with it, and more cost effective.
