throttle plate

[PaulGTP]

Where can you get a 70 mm throttle plate, I'm assuming that is a max you can fit it in the plennum of 91-93 W-body. and what is a max bore for the plennum

Thanks

have to have one made somewhere as far as I know. TB and plenum are the same, so I dunno what you are asking exactly. 70mm should fit, but I was planning on using 69mm TBs before I gave up on the stock plenum design. The area behind the TB is probably closer to 50mm diameter, stretched out. Not much you can do with that design.

i have 4 plates left. i am having my plenum horizontal milled to the exact size of the plate
