Lets see your modded B Head Intakes.

The only Throttle Body I've seen is the Accufab. Are you guys grinding out the openings on these intakes? What other mods to these for boost?

Yes, I cut out the divider by the throttle body on my plenum.

Cool. Who else makes a single plate TB? The price on the AF is steep!

What power are you even making? The stock TB ins't a restriction till like 600...

I don't know man.. The problem with these motors is that there's not a lot of aftermarket options with Intakes for these motors.. I think a Navigator Tumble Port for the street would be great, but Intakes are scarce..

Here's mine. I smoothed the intake both externally and internally. The EGR and vacuum cast ports are completely ground smooth inside. Everything is TIG welded.

Got any pictures of the process?

 

[RJCarp2]

Not really. Just finished product pics. Cut it all off, weld it all up. Then I machined a mounting block for the IAC and mounted the block and IAC at the very back of the intake so it's out of sight.

RJCarp2, how about a picture of the IAC current location. I had thought about using a remote kit but I could weld it onto the back of the intake. I also do not have a Cobra, my 4v is going in a '68 F-100.

Here you go. I machined that mounting block. Inlet air to the IAC turns 90 degrees in the block. Then I simply drilled and tapped the intake. I used a 3/4 NPT bushing at the intake. I tapped the intake deep so the bushing threaded almost all the way. Then I cut off the extra threads so it was flush on the inside and I epoxied it in place.
