Holley TBI Adapter... What TBI unit has same size bores?
I have one of these and a Holley Dominator Intake Manifold coming for my car early next week, and I wanted to know what size throttle body fits on this spacer? Would a L05 tbi work? or would I have to get a 454SS or Holley TBI unit? Is it possible to just bore out my L03 TBI to match.
Thanks for the replies, if any
Clint

Not sure I understand what you are trying to do but. small block TBIs have 1 11/16" bores (including l05) and big blocks and the Holley have 2" bores. The bolt pattern is the same. And, yes, it is possible to bore the stock manifold but since you're getting the Dominator, I'm not sure why you're asking. Hope this is some useful info.

If you're running the stock motor (basically) then use the stock TBI unit with the Holley intake. The bores on the intake will just be bigger (2 inches as opposed to 1 11/16 inches)
That is pretty much what I wanted to know, whether or not it was time to move forward with a larger unit or not. I will definately do that when I get the vortec heads and RPM Air-Gap intake.
That hood has a fake shaker scoop bolted onto it. It was part of the Bandit II package, that had all of the pinstriping, hoodbird, etc. Right now I have a 86' Trans Am hood on it with a Harwood 2 1/4" cowl scoop to feed my car fresh air.
For more information on Bandit II, here is a site I made for it.
I do have one from a 80 or 81 4.9 T/A. I did not use it because it would be too hard to get it to work. I know there are places that will make them custom to your car. I know someone who knows places. Let me talk to him, and I'll try and pass on the info.
