XR 4x4 MT75 4x4 to 5 litre V8 conversion
This is going to be a long running project as I'm short on spare time at the moment
The first part of the jigsaw is made, a 16mm thick aluminium adaptor plate to mate a Ford 302 to a MT74 4x4 box.
Flywheel is still to be made as well as sorting out a sump/diff arrangement.

Arent you afraif your car will be nose heavy ?
I am also in the middle of putting a V8 lump in the front of my Sierra XR4X4, with the cologne V6 the car has a awfully heavy nose, the understeer is acting really badly..
You are installing a big iron Ford V8 in the place of a already heavy engine... are you prepared the car will handle really bad ?
Maybe you should consider a lighter rover V8 engine or go a little more modern, BMW, MB, Nissan, Toyota. I choose Toyota, after some lightening i have a 166kg engine insted of the stock 270kg of old cologne iron rust. I am starting with 280bhp stock, ready to be blown or revved hard for much more...

I will have to put up with the handling, the Ford 302 is the lightest of the iron V8 engines and I may be able to get some aluminium heads etc to keep the weight down.
The problem with every alloy V8 I've looked at is the fact that the casting extends down too far below the CL of the crank meaning the front diff will hit the block
I started off with a 3.9 Rover V8 but that was no good.
The Toyota/Lexus no good.
Audi V8 no good.
LS1 no good and way out of my budget.
The 302 extends only around 3mm below the crank CL, the Rover v8 around 57mm.

I see the problem Mark but there is a solution with the Toyota V8. The differential, when the oil pan is properly made will sit on the side if the engine. The oil pan flange is narrow, much more narrow than the V6 cologne. Whats more important there is no offset present in the V6.
Take a look here, here and here.
Aluminium heads would be sweet, thats a big weight gain and a lot to offer in handling.
Will you be using a custom made flywheel ? Judging by the flange yes.

IF this web site is correct the 302 weighs in at 209KGs

Aluminium heads, tubular headers ect should get some weight off.
My next job is to make a flywheel that will take the 2.9 ring gear and Cosworth clutch.
How far have you got with the Toyota V8 conversion, any more pics ?

Thanks for the comments, the prices of parts for the 302 are so cheap it's unreal. Check out some of the prices here

I can see a nice set of big valve aluminium heads eating up my Christmas club money
