4.6 engine swap into p6b

Hi all,

I've scoured different forums and book of faces and I thought I'd make a list of everything that I'll need to swap in a 4.6 into my p6b. Ron and others, can you chime in with your experiences and thoughts on what I'll need?

Engine:
4.6 block - top hat linered
heads - I have SD1 heads and 4.6 heads. Which would be better to have ported etc? *edit* 4.6 heads with composite gaskets?
Crank/Rods/Pistons - haven't decided. Probably standard crank, maybe standard rods? ARP bolts
Intake - Offenhauser
Carb - AFB/Edelbrock
Ignition - ? P6b distributor with Illuminition kit?
Front timing cover - SD1 or P6b. Any thoughts on which is better?
Sump - p6b
Camshaft - no idea. Can I use the 4.6 one or will I need to use something else if I run a distributor?

Flywheel - I have a 3500S one
Clutch - ?/I have a 3500S one but I don't think it will work with the W58
Master - brake?
Slave - have a Dellow one to suit.
Gearbox - W58
Shifter and shifter housing
Speedo cable - custom?

Tailshaft - custom

Down the track:
Complete Jag IRS with XJ40 outboard brakes
Complete front jag IFS or just Jag brakes.

Have but not fitted:
Uprated sway bar

Hit me with your feedback and ideas. What worked for you or didn't work?
The original motor is going on an engine stand and I have access to a few dead p6bs as well.

Edit. Will also put in a better fuel pump and probably run new lines. I also want to do away with 1 of the 2 charcoal canisters.

The later heads would be better. I don't think the ports are any different, but there are more bolt-holes for ancillaries.
And the later heads are right for composite gaskets.

I would go with an SD1 electronic ignition system. Use the SD1 front cover as the oil pump is better (i.e. bigger).

You will need a camshaft that will run a distributor.

Standard 4.6 crank/rods/pistons are over-specced. People run silly powers on the drag-strip before they fail.

Chris.

Cheers Chris

SD1 front cover and pump - on the list
Camshaft - not sure on make or spec yet. Ideally I want lots of torque in the midrange.

Crow Cams in Campbellfield Vic make various 4.6 cams - they have a towing cam that provides best torque in the mid range but still good lower down. I have one in my 4.6 as I also need higher torque in the midrange.

You can order the 4.6 cam with a dissy drive on the end.

Also you can order cams to your specification.
