Heres mine after an Mbe ecu fit and a new 885 cam all on a standard size plenum pre cats removed main cat still in cars on 75 k runs like a dream no shunting and just a lovely car to drive now .
"Lovely to drive" my 4.6 on Mbe and 885 display similar wonderfully easy properties from 900-6000 revs and as these lines show is very smooth to drive and indeed lovely to own.
Reading this thread with great interest, as I'm hopefully going to see about getting the cam changed in my 4.0 this coming winter.
The only slight complication with mine is that there is a slight uncertainty as to whether it's a 4.0 or a 4.0 HC - car was purchased on the basis of it being a 4.0, but does have a 400 HC badge on the plenum. Seller wasn't sure, which I took to mean it's likely just a case of a badge swap, but no way of checking presumably without looking at the pistons.
Either way, it's at 76,000 miles and definitely feels a touch 'flat' above 4000rpm so a new cam is definitely in the pipeline.
My main idea so far (assuming mine is a normal 400) has been to go for the MC1 - but this topic is giving me plenty of food for thought!

Bore scope down a plug hole will tell you what you need to know if you have eyebrows/valve reliefs cut in the piston the field just got bigger for cam choice my advice on a stock motor dont go too radical with your cam choice The only slight complication with mine is that there is a slight uncertainty as to whether it's a 4.0 or a 4.0 HC - car was purchased on the basis of it being a 4.0, but does have a 400 HC badge on the plenum.

Just to add - you can get USB endoscopes on eBay that work with your smart phone for less than a tenner. Worked a treat on mine to prove I have no pockets and it's a bog standard 400...

I might check while it has it's 12k service next month in that case. Nope didn't want anything radical, but if there were any mild improvements to be made via the cam change (for little cost difference over OEM) I figured I may as well!Gassing Station | Chimaera | Top of Page | What's New | My Stuff
