What type of camshaft will work with older carbed 302's, like in a 79-82 Vic? A hydraulic flat tappet or roller tappet? Or does it have to be a mechanical roller or flat tappet?

hydraulic flat tappet cams work on the older pre 86 5.0s. You can convert to hydraulic roller, merchanical flat tappet or merchanical roller. Just depends on how much $$$ you got and if you want metal shavings in your motor.

So for, say an 82 Vic the stock cam type is hydraulic flat tappet? Then that's the type i'll use, when I get a Vic that is.88 Town Car (wrecked, for sale)

Mechanical roller FTW!Comment

Uhm, that ain't no Chevy world, last time I checked the 5.0 still had pedestal mount rockers - how exactly do you plan on adjusting valve lash? You put the cam and the lifters in and hope all is right on the money, but what if it ain't?Originally posted by JumboFriendlyComment

I basically have no idea what I'm talking about when it comes to camshafts, so disregard any posts of mine in this thread. That said, a friend used to have a 289 in a Mustang with a pretty aggressive mechanical roller cam, and it sounded sweet.Comment

That is what they make pedestal shims and different length pushrods for...Originally posted by MeLikeyStripperChicks

How are you going to get shavings by switching cam styles unless you are going to try and bubba it?Originally posted by MercmarquisComment

maybe from roller-retrofit cams not lasting as long as a normal cam? :confused:

All roller cams are steel. They last just as long.Originally posted by phayzer5Comment

Unless they buy cheap parts and they fail, mechanical roller cams will not put any "trash" in your motor.Originally posted by MercmarquisComment

probably just as much from insufficient oiling and overly tight valvetrain adjustments as anything. I've seen marine high performance Chevy big blocks wipe camshafts out for this reason. Big valve springs and no modifications to add more oil to the camshafts just takes the lobes right off. Motors get full of trash when that happens. It also usually happens on the motors that people crank the rockers down tighter on.86 Lincoln Town Car (Galactica).

Solid lifter cams need less oiling. High RPMs can necessitate spring oiling. Flat tappet cams are more suseptible to wiping out the cam. Overly tight valvetrain adjustments will only keep your valves open and likely not hurt your cam although you may create more heat which would be hard on your springs. Your power would be down as would your peak RPMs. You would have to experience piston to valve contact to hurt parts.Comment
