318 cam in a 360 hmmm.... i have a magnum 318 sitting out behind my shop.... i wondering if i should pull the cam out and stuff it into my 360

 

the cam in the '18 went into a Jeep motor once, if I'm to believe what I've read.. the Grand Cherokee.. it was substantially peppier those same folks claim.. I reckon I believe them..

 

As long as the cam is in good shape, it'd be pretty much a free upgrade. I've got 2 at home I've thought about putting in mine.

 

318 with H&S 1.7 RRs and a tune and she's a happy camper!

 

Hmm this has sparked my interest. Might have to think about this for a while.

 

I would not use a used camshaft. However, my experience with using a used camshaft was with a hyd flat tappet cam, not a hyd roller.

 

Oh, and the reason it responde better to mods is because if you put 1.7RRs on it, the lift increase rom the rocker arm ratio bump will be greater in a cam that already has higher lift.

That is why it responds better.

 

flat tappet cams are much more likely to be worn down or not break in right causing them to wear down fast..
This is an issue I see in the vw forums alot... also flat tappet cammed vehicles should have special oil or at least an additive that included things like zinc to provide better lubrication... many dont know this and use modern oils which have most of those lubricating properties stripped in an effort to make it more emissions and cat converter safe... so yeah a lot of those used cams are toast.

 

very true but combine that with a more aggressive cam with more lift and you have even more response so....

 

if i was going through all that effort, there is no way I'd mess with that particular cam..

you'd want to do it right, right? that means new lifters, new bearings, new lifter rods, and obviously new gaskets.. that is around $300 by itself.. a new cam can be had for another $300~$400- and in a sausage profile (down low), 201x (low to mid), 205x (mid to high) or a floggin' 210x or higher for straight up high rev ridiculousness.. The '18r would hardly be worth the effort is what I'm getting at..
