Default Wenzler Gutsram manifold

Is this manifold still being made? I've emailed them but no reply as of yet.
Does anyone here have one for sale, I want the one with the tapered runners and cast in nitrous bosses, I don't need the dual quad top. Thanks.

Yes they are still being made, I bought one from Larry about a year ago. Did you try to call the shop?

I would think that even a internet novice would be able to gleen that info on the information highway. By simply typing in wenzler manifolds I was able to find it.....took all of about 5 seconds:
http://www.wenzlerengineering.com/PONTIAC.HTM

If the O/P was savvy enough to send an e-mail.....he can easily find the # to call. I would assume it is much cheaper for him to e-mail than to call (since he is from the U.K.)

Ok, Larry has emailed back, initially looking at his site I wasn't sure if it was just old info left on the net. I prefer to email questions to any vendors so that I have a reference/record of what has been said. No mis-understandings that way.

Yep, just bought one from him without the top, going to use a Holley LS efi manifold top on it to make an efi manifold for my sons big single turbo combo. Very reasonable at $325 without the top,I thought.

Nice set-up! Larry might raise his pricing once he sees what is being done with them.

This is the Holley hi ram top 300-217 and 300-218. You won't have to use the 300-217 Blank Configurable Top. I am just for added plenum volume.

Are there any issues with moving the outer bolts outward the 1/2" or is it pretty straight forward? My kre 380 gaskets came slotted already, ive never seen this before.

I haven't got that far yet. I does look pretty straight forward. Transfer punch and a tap should do it.

Thirdgen, yes a good way to get a modern efi manifold with plenty of plenum volume- TomV's post in the street section showed a pic of the Holley top and I hadn't thought of it 'til then. Bnick166, I thought the same thing so bought immediately just in case!
JSPont, yeah we will do , still collecting parts for the engine build at the moment-waiting for our rotating assembly parts etc to come in from KRE , using another '59 389 block for this build too-with the mods I said I would never do again- welded up valley/mains girdle etc, so may have a couple of threads to start!
I'm also putting the Holley 300-218 efi top on my own modified Offy 360 dual quad intake, but siting the injectors in 1" thick ali spacers just under the top - I want the fuel injected up high in my manifold. I'll post some pics of that too when the top comes in.

Any updates on this intake? I’ve been throwing around the idea of doing one of these without the extra plenum area added for a turbo build. Does anyone know the intake height to the flange where the adapter would bolt to? I could have cnc adapter plates made to mate the Holley piece to the Wenzler piece pretty easily if it would fit under my TA hood.
