Bob
So you want to install a Hemi in a A body using factory mounts?????. Your a brave man Hope you have alot of patience, specially if your using box headers (Hooker/TTI etc.). If you want to use an external oil pickup system, stay with a single line, because a dual line is ALMOST not doable without doing alot of cutting OR fabricating of mounts, & creating a new pickup port in the pump body because the "as delivered" ports will now allow for that second line.
As your probably aware Hurst/Chrysler utized the welded steel mounts on the K member from Hemi B Bodies to build the original Hemi A cars.The rubber insulators were also used.
The tubes they used were Hooker 2" & were delivered with a street hemi pan. This combination worked as is but did not allow for the oiling required for a high winding Hemi. So, the cutting started on both the drivers side mount & steering box mount.
Now getting back on track to your install, the easiest will no doubt be an engine plate with a torque restrictor to limit fore & aft. movement.This will allow for dual external oiling & lots of header clearance
If your interested in this next option, pm me & I'll give you the name/number of a buddy who fabricates 2 different Hemi A body K members as complete bolt in kits utilizing original style mounts, original K members & suspension . The first one he designed a few years back that locates the engine a little lower than stock, which allows for much needed trans tunnel/ header clearance. This K member will accomodate box headers. You'll have to ask him about 2 1/8" tho. I believe it'll only work with a single feed external oil system.
The other K member he has available is a direct replacement of the originals, location wise. I know that because he borrowed my original to build his jig.
My Hemi install is a little unique as I'm using an unmodified original style K member with custom built headers, custom fabbed engine mount made from DOM 1 3/4" tubing & a modified Milodon dual oiling system. MANY, MANY hours were spent making this work & all clearances for everything in that area are minimal. 1/16" is the difference of something fitting or interfering.
This is the passenger side mount

This is the drivers side mount

If you closely you can see the new oil location at the bottom of the pump. The original 2 rear pickup locations remain plugged

This is the almost ready to install assembly. Tubes are custom made . 2 1/8" primaries, 4" collectors. Passenger side is 2 piece, Drivers side is 5 piece. I need to remove both torsion bars, both tie rod assemblies, center link, have no starter or even the drain plg in the block to get them in. I can't even have the header gasket glued to the head for install, because the thickness of that gasket won't allow #1 tube to go in, even with the engine lifted. The gasket needs to be slipped in after the headers installed.

have I scared you yet? They're not all this tight. I sold Dave McDade an original unmodified Hemi A Body K member & he installed it with the motor attached from the bottom. He dropped the body over the assembly. Valve covers were off tho. I don't believe he has an external oil system & I think his tubes are 2". Feel free to ask whatever you need to get that elfunt installed, & I'll do what I can to help you out.
