I think you should do alot of other mods first. I have done 14.5 on a stock TB unit.

Keep your stock one, you won't notice a difference with either of those without extensive mods and chip work.

You do not need one of those now. I know plenty of people (including me) who have cammed set-ups and run the stock TBI unit. If you did buy it, put it an a shelf for a later day.

Yep. This is the danger with drinking more than 4 Rolling Rocks while surfing eBay with a PayPal account in good standing.

I woke up this morning and scraped the idea. Still... it's good to know these are out there.

True or False: The Ultimate TBI mod is basically boring out the barrels of the throttle body and adding a spacer.

Thats to wierd I've got about 6 of those type of throttle bodies in my watch list.
I need a new pod and figured I'd practice grinding on the throttle body and do the ultimate tbi mod to the fuel pressure regulator.
But I heard as well it's a bit premature to get the throttle body as a first major mod.
It's good to know theres lots of them out there though.

I've have to have ebay free days otherwise I'm staring at 'SBC' headers and clear marker lenses for hours..

Dude look in parts cars and search for firebird/camaros..then the dreaming will really begin
