Holley 670 vs. Turbocity TBI
Anybody have any experience on which is better? Got a mildly worked 350...I prefer to keep the Performer intake I have now (1 11/16" bores). The Holley with 2" bores would require an adapter...I'm not quite sure, but it looks like the Turbocity bores are 2" too (I see from the website they're machined out, not sure if they're opened to 2" or not).

The Turbo City tbi is not 2". What are you using now, sounds like you have a pretty good setup already. Find a junk tb from a salvage yard and do the ultimate tbi mods to it then swap everthiing over from the one your using now. Until you swap intake manifolds you don't really need a larger tb.
