Here is what I have already,
1990 suburban, all stock, 2wd, TBI350 motor runs fine other than smoke from valve seal
set of long tube headers (not installed)
cheapo thrush (2)mufflers with 2.5" piping all the way back (not installed)
Throttle body spacer (not installed)
new shiny air cleaner (just put on today, no noticeable gain but sounds good)
a set of camel hump heads with the 1.94 valves (not installed)

I want more get up and go out of suburban, 300hp is the goal. I did Not plan on pulling the motor out or touching the bottom end at all. Now here is the tricky part, I want to keep the TBI for reliability reasons and I love having my remote start http://www.clubhotrod.com/images/icons/icon12.png

My plans are to Install all parts listed above along with:
electric fans
no cat converters
maybe bypass EGR or do some emissions modifying? (info needed on this subject)
gasket match port the heads and intake
All new gaskets of course

And I am debating on the holly throttle body unit that comes with the bigger injectors? and/or some MILD cam options. As I said before I want to keep it fuel injected and have no tuning experience or access to a dyno. I hope to be able to just get it close enough and run 93 octane always.

Does this sound doable? Is there anything I should add to my list or take off of it? What do I do for the fuel side of it? bigger injectors? FPR? Is this doable for under a grand? What are peoples opinions of the holley throttle body?
