3.4 throttle body?

[Kronos]

I've noticed recently looking around a bit people modifying the upper intake manifold for v8 throttle body apps. Can anyone give me a point in the right direction, I've been looking for a few days and really haven't come across anything worth looking into.

i think their throttle body is a direct bolt on. as far as intake manifold modification, that's over my head. [img]graemlins/banana.gif[/img]

i believe that hes lookin for a TB like mine. They only way to do is cut and weld a new piece for the TB to bottle to. i think i have pics on my site.

is there any specific piece generally used to do this, or is it more of something that I would have to get someone to fabricate for me? The new piece that the tb would bolt to I mean?

Here are some pics of mine:

Sorry for the blurry pics...it was a crappy camera(and no I'm not still holding my throttle cable on w/ cable-ties [img]tongue.gif[/img] ).

That piece that's added on it a milled out solid block of aluminum. And then it was welded onto the cut off stock intake. It came out very nice I think. I had a machinest where I work fab it up for me. I basically just told him what I wanted to do and gave him the stock intake and LT1 throttle body and he did the rest.

There might still be a few places out there that will do this mod to a 3.4 intake but it's always been super pricey. But any good machinest/fabricator should be able to do it.

Hey TurboProject, did you notice any difference with that larger throttle body? I was always told that that mod was a waste because our intake manifold doesn't have enough flow for a bigger throttle body to make a difference.

What size TB is that, by the way?

It's a stock LT1 twin 48mm throttle body.

I noticed a little bit of difference in throttle response. But not much as far as a gain. But I wasn't expecting much. I just put it on my stock engine/manifold.

However, with the new engine I'm building up with ported heads and upper/lower intake I'm sure it'll help from keeping the throttle body as being the bottle neck.
