Sbc Turbo Build Questions?

So this morning I woke up and thought a turbo'd 55 Chevy gasser would be cooler then a supercharged one, plus id make more power! And cost about the same. The problem is I don't know where to start, I'm not familiar with turbos! What parts will I all need I know for sure I need a blow through carb or at least convert one to. If I can find a good kit for 2-3 thousand awesome, if I can build something that works that is cheaper even better! The engine is a 9:2:1 flat top 355 010 4 bolt main block, stock short block, small cam its actually perfect for boost 114 lsa, vortec heads, and that's about it. I want something that will work on the stock short block but has room to grow once I build something with forged internals. Any info helps, any junk yard builds with great success I would like to hear too, budget in mind, but don't mind saving and spending 3 grand if it's worth it.

you can fab up a decent single turbo system for your budget or less, intercool it if you can, you'll probably only need about 5-10psi and with a really good tune can get away with pump premium (93 octane).

building your own blowthrough carb requires a lot of attention to detail- its not something you want to mess up, and make sure you keep a very close eye on a/f ratios and detonation when you're doing the tuning.

A 350 with flat-top pistons and 64cc heads will be closer to 10.2:1 static compression ratio, not 9.2:1. You have some changes to make before you start puffin' boost into THAT motor.

There are many advantages to mounting the turbo(s) at the back of the car.
STS Turbo, Inc. - Turbocharged Innovation!

including a cooler charge air temperature without intercooling which allows more boost with mid 9.xx compression on pump gas.

single or twin turbo? a couple GT-40s on headers can take you a long ways. 700 hp should be no problem.keep your mixture mid 12s for safety. I think 3,000 is optimistic.

I like the idea of a single, twin seems like too much crap in the engine compartment lol

I said twin turbo because that makes it very fast to spool up with reverse facing headers putting 2 little turbos out front. A single turbo is more than enough for decent boost.
