Frankenplenum

[LGAFF]

I don't know what will happen, but its a 90 Z with 144K miles on it, and a bunch of parts that I got hacked up....so nothing to lose. Possible my cams might be a restriction...and the fact that the heads narrow to 32.5 on the primary ports as they enter the head.

We will see....good times

[LGAFF]

I think the plan will be to weld 1/2 solid square stock to the intake opening, then build a lid to make it modular as new Holley Hi Ram LS intake is....

this will allow for volume variance, as well as testing divided plenums, etc....

Will also ensure when its welded up I can check the runners and clean them up

If you need to cut the hood on the black car.. I will trade you hoods before cutting

[Bearly Flying]

Would there be any advantage to extending the individual runners into the plenum, ala the LS series of intakes?

[batchman]

Or in adding the volume in the valley, after having removed A/C, relocated coils, removed secondary actuators, re-done PCV?

A lot of room under there, too bad you can't readily relocate the starter or alternator...

Hmmm,

Tacked a few 3/8 steel plates together, getting reading for the welder

Yes they are ugly welds

[LGAFF]

Plan will be to weld 1/2 X 1 inch flat stock or 1/2 X 1/2 square stock to the edge....then build a top with 1/2 inch stock, will need to check for clearance on the outer edge first

Lee, You are going to have to create a way to cool the Aluminum faster as you TIG or you will warp the flanges. The 3/8" Steel that you are bolting to the plenum will not move heat fast enough to keep the flange from warping.

Its actually two 3/8 plates welded together.....I will let the welder address the cooling, he did my Airhorn and no issues.

Volume !!
