Alright my friend has a chevy blazer with a 383 installed in it. It has a good bit of power for what it is. I think it was all pretty low line using stock type heads and crank. The only problem I see is it has a tbi fuel injection system I dont know what car or truck it is from but I believe it is relativly stock. I dont think its really what the engine needs but I want fuel injection and want to know if I can upgrade this cheaply. I thought of the lt1 intake conversion but I dont know if I could use the wiring harness and computer I would have already. MOney is a big issue so what about a 454 throttle body and a chip or something. Id say my engine is built for 375 hp right now thats about it. I just found this http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2408616225&category=6770
