So I have a 4.6 and a cam....will they like each other?

[Oldskoolrob]

Short story long, I'm putting a 3.5 into my Mk2 Cortina. I've been keeping an eye out for a cheap 4.6 (for later, the 3.5 has to go in for the car to be certified as I'm only 'supposed' to go to 3.7L max capacity) and I managed to get one at price I couldn't resist. Before I got assurances from a mate who is a retired mechanic that the cam in my 3.5 is fine, I had already bought a new one for it (see attached cam card). So now I wonder if this cam will be ok in my 4.6 when the time comes to rebuild it, with 3.5 timing case etc as I want a dizzy, and I need it to remain looking like a 3.5 (intake is edelbrock/holley). By my maths it should be ok, but I am no expert.

I chose one for my car, 4.0L tuned manual, fast road.

Not easy to tell from the data, but does the advertising blurb state what engines its designed for? Most of them will say any Rover V8, or up to 4L, or 4.0L and up. Some will say designed for heavier cars and autos, so a 2 tonne auto Range Rover for instance, or best suited for a fast road manual.

I found a list of cams somewhere (now in XL) and it lists ERR5250 for the 4.6 -

Hi John,

ERR5250 is a genuine asymmetrical camshaft for the factory 4.6 litre engine meaning there is no nose on the camshaft. There is no provision to drive a distributor as the 4.6 didn't have one.

Maybe something that fits the V8, with similar timing is out there?
