V8 Swap Chassis Position

Happy Labor Day, all! I'm building a Series IIa 109 wagon with the following:
New Galvy Chassis from Richard's
Chevrolet GenIV 5.3
Muncie M22 4 Speed
Ashcroft HRT
Stock axles/driveshafts

When I bought this car, it had a sloppily installed Chevy 350 mated to the rest of the drivetrain, so I don't know what it looked like when it originally had the inline 6. Looking at blueprints online, it looks like the original inline 6 was positioned between the frame rails off-center, about 6 inches to the left of center.

For the V8 swaps, are people centering the engine in the chassis, or placing it closer to the left frame rail? In the former position and retaining the rear tranny mounts, the entire drivetrain is skewed ~5 degrees from center which might be bad for the driveshafts. Is placing the engine centerline closer to one side but parallel to the frame rails the best way forward?

thanks!

Your question is way above my pay grade, but you can call Advance Adapters' LR guy & ask him:
Profile for Matthew Jackson | Advance Adapters

And an article on his own Series V8 swap:
1960 Land Rover Series II - O.G. Rover

Other poop from my folder on this topic:
Converting a Series Land Rover to a V8

Some say those Series with the v8 swapped in get really hot in the passenger compartment - is that your experience?

Thanks for the link to Matthew's article and contact. I sent him an email. My car does use the an Advance Adapters 1135, which I presume is an older version of the one they sell now. I'm doing the mockup using my old chassis which is bent, so my measurements are not exact, but it'll be good to get some clarification for when the new one shows up. It got held up in the gulf outside of Houston last week due to the hurricane.

As for heat, I've heard that the all-aluminum LS engines run fairly cool. The old engine was junk when I bought it, so I don't know how it will do. I'm guessing careful attention to exhaust shielding will be key.

Offset is closer to 1". The engine and chassis brackets are asymmetrical. I'm assuming the HRT is a LT230. If so, you'll want to use the factory brackets and slightly shift the engine to center the exhaust manifolds equally in the frame rails. Wherever things fall at that point determine the engine mount locations. Slight offset angle of the driveshaft will not be a huge problem but the angle should not exceed 1.5 degrees under normal operation to ensure u-joint longivity. Ideally u-joint angles would equal and opposite at each end of the driveshaft to prevent opposing rotational speeds. Note that the driveshaft u-joint angles shift constantly anyhow when driving down the road.

Thanks, Mark. That's a good point about the exhaust. Do you have any manifold/header recommendations? I see that the Defender swaps are using the Hooker 8501HKR, but I've seen other LS boards saying great things about Sanderson.

I picked up the new chassis last week and got the axles transferred over. I also removed the stock engine mounts, though there was a pain in my gut as I took the angle grinder to a brand new chassis. Forward momentum! I picked up a set of Hooker 8501HKR manifolds and hope to get the new engine mounts in place and welded in this weekend. I'm using Dirty Dingo LS mounts and they fit well as-is, but I'll likely need to do some manipulation to get the positioning perfect.

Here are current pictures. The last is comparing the stock truck manifold to the Hooker. It's definitely tighter to the block and dumps down closer to the front of the engine than stock. All the Defender guys use them, so it must be close enough.

I had some time today so I did a test fit to see how the brackets need to be made. Overall I'm pleased with the clearance, though the exhaust manifolds do indeed dictate position. Here's what I see:
Front propshaft has sufficient clearance, but the rear propshaft hits the chassis. I'm hoping that the weight of the body will help settle the rear springs. I can also go to the lower 1-ton shackle mounts if needed.
The parking brake pivot won't fit with the existing rear mounts. I'll need to fabricate around it for the new ones.
The valves are normally covered... I took it off for the pictures.

Anything else you guys see before I start welding?

That's a P38 box. Richard's added the mount to the build before they galvanized it.
