Are there any adaptor plates out there? If not, where do I get one?
Or am I going to have to make one?
I was thinking of just finding a Performer TBI manifold, but I want to possibly boar the TB to 48mm for the TPI throttle blades + ultimate TBI mods.

Would it be possible to boar out an intake manifold to accept the larger TB instead of the stock boar size?

 

You should be able to get one from Holley.Some of these guys might have a part no. and where to call to.

 

I'm not sure, but I am guessing that this is the one I would need. PN 17-45 After looking at all the plates they offer, I assume this is the one. Correct me if I am wrong.

I want to be able to boar it out for the 48mm though. It doesn't look like that will be possible from the way the pic looks though.

 

That looks like it.I don't think you are going to be able to bore it out too much though.

 

why dont u get a tbi manifold and bore that out... i dont see why that cant be done

 

You can't boar out a tbi manifold because the water passages are very close. But there are some who have done (lucky).

 

well theres gotta be a few millimeters...and1 actually bore t out on the board?

 

Holley has adapter plates for throttle body to regular carb intakes for both spreadbore and squarebore intakes and I believe they have 2 inch bores, mikeb.:hail:

 

Holley's part #17-45 is 2inch so it is already at 50.8mm so you wouldn't need any boring

 

normally i wouldnt take advice from somebody that has as many female qualities as that guys pic shows, but he is correct.

 

Well, this is great then. I might have to buy me one of these. Anyone around here know how much they cost? I would hate to have to spend a ton of money on it. But I guess it is something that is needed.

Thanks for answering my questions.
