G`day Chad ,

all the bits from a 3.5 will fit , if a bit fits on a 3.5 it will physically fit a 4.6 and the other way as well .

On the outside , other than some bolt sizes for ancillaries they have the same dimensions .


If don`t want to a use a distributor you would need the rest of the front off the engine , water pump , pullys ETC .

If you want to use a distributor you`d need to change the camshaft and use a 3.5 timing cover/waterpump ETC .

Then you only really need a spacer for the crankshaft , which you can make out of a crankshaft timing gear by removing the teeth or buy or make a spacer and depending on the 3.5 you may have to look at the crankcase breathing setup .

Cheers

Looks like left over Land Rover stock, not Coscast.

Yes it will all transfer over - I have one in my SD1 car fitted with Edelbrock and Buick heads.

You can use your 3.5 front cover and oil pump in place of the 4.6 one already fitted if you want to retain a dissy ignition. Crank spacers are available from many RV8 specialists or you can make one up easily (the 4.6 crank is longer than the 3.5).

Change the cam for a non injection high torque type, and lifters too.

Plumb the breather from the rocker cover into the front of the Edelbrock.

Whats that you have 4.6 in an sd1

So did you get it?

AFAIR , you also have to cut a couple of dowels off the crankshaft rear end.
