2 L67 Inlet manifold questions

[Brysha89]

Hello JC Forumer's I am looking for pictures of L67 inlet manifolds for the purpose of drawing so far i have drawn a aus L67 charger, and the us charger as well i have drawn the aus L67 inlet manifold but now am up to the us one and when i search it in Google i only get pics of the one like aus.

So my questions are
1: are they the same inlet manifold? ( I suspect not as the throttle body housing is opposite side)
2: could someone who has a L67 inlet manifold lying around or if you are doing a gasket swap and have one off measure the under side of it top to bottom.

This is for the the purpose of getting a price to fabricate a duel into one for a l98 to see if it's fessable for me to do, For my plan is to put twin L67's both running 20psi plus twin turbo for a drag engine i'd like to build, sofar i have nearly enough for a full internal rebuild kit for the l98 just would need to send block away to be cleaned and honed, and yes i know it would be better to go a twin v8 supercharger/ twin turbo setup but the 6ltr v8 chargers alone are too pricey and the chargers would get negated by the turbo's after the lagg of 30psi, so i would like to go L67 chargers with a 20psi as they are cheaper to fix and to just buy 2nd hand and there's a few around.

Appreciate any thought's and info on this matter i am not going to change my mind on using L67 chargers but would still like to every one who drops by this post's thoughts i am still drawing the us charger but when i finish them i will post them up for every one to see as well.

I happen to have L67 inlet manifold that had a M90 blower on it laying around ATM, as a project to try and repair (remove a broken bolt in it),
We’re you say measure the underside top and bottom, not sure what you mean.
I will take a couple of photos and let me know the area you need measured.

i would like the underside of the inlet manifold measured the part that sits on top of the block just a length not width would be sufficient as i want to measure it compared to a l98 manifold and how much it would need to be lengthened to add the 4th rectangle port to be added to it

a pic of the underside and side would be good too as i cant seem to find them pics

Images attached as requested,
Any further information required, let me know.

Left side of the images is the front of the engine.

The only problem I can see, maybe the Thermostat seat and water jacket could be a problem for the 4th port eitherside.

was thinking extend the front but the internals are going to be plumbed to suit the l98 heads ill quickly draw how i intend to plumb it

I will be watching this thread. I'd be interested to see how it works and whether an M90 could be fitted on early V6.

losh i am fitting it to a l98 v8 not the old buick v6
