gians from TB
Arizona Speed and Marine makes good TB's. I wouldn't go bigger TB till you are making more HP around 395 RWHP. Most people get a new TB with new heads/cam or nitrous and forced induction applications. Any one of the sponors should carry TB's. 58mm seems pretty popular as an upgrade to heads/cam.
Your best bet is to get it ported, do it yourself, or just give it to Jantzer. He does a really good job on them. Might want to do a seach on him though, some people have had some problems with him. Other than that Jantzer is the best, I was really satisfied with him work. With your mods your definitly going to see a nice gain, iam guessing 10 plus hp.

Yeah I noticed that, I keep thinking everyone has an LT1
