I want to put a mopar purple cam in a '00 4.0 but was told that i couldn't without changing a lot of the cam and timing chain related parts to the older pre-99 style....

can anyone provide me a list of the parts necessary to do this swap? or point me in the direction of a how-to?

Searching is pretty useless since the word CAM is too short to be a valid search string in our search engine and without narrowing it down from their all i get is a bunch of stuff about earlier 4.0's.

Thanks in advance.

Chrysler revised the cam in 1999 (did not change the grind)
by changing to a different diameter bolt and a retainer plate bolted to the
block to prevent the camshaft from walking toward the radiator. The '98 and
earlier 4.0 engines used a bolt with a spring and thrust pin counter bored into the bolt head that rides against the timing cover to keep the camshaft in place.
The after market camshafts that I know of are made in the earlier style, and this is why the manufacturers show them only up to '98.

Conversion parts

'98 and earlier cam bolt kit (bolt, washer, spring, thrust pin)
'94-'98 camshaft sprocket (Get a Cloyes set, I don't believe in mixing and matching chain set wear patterns, some feel it is okay, not on my motors.)
The '94-'98 timing chain and crankshaft sprocket are the same as
the '99+ and could be reused if in good condition. Reuse the '99+ timing cover, and delete the '99+ camshaft retainer
plate.

Any more questions, let me know.

-Erik <--- suprised it wasn't easier to get as response on this... i guess not many people are camming their newer 4.0's?
