Was recently advised that my cam has given up a lobe or two & will need replacement.

I've looked through my current array of catalogs including Pargaon, LICS, etc. to no avail.

Breifly looked on line @ Jegs & Summit but have been unsuccessful.

Any guidance appreciated.

What engine do you need a cam for? There is no information in your post or profile.

You guys are quick today.......

I have 69 Corvette 427 block with the correct 208 heads for my 65 396 car. I have previously purchased the correct block for the car but will wait another year or 2 to install it. I'd rather purchase the correct cam for a 396 & install it in the current engine with hopes to use it in the 396 block at a later date.

To the best of my knowledge a 65 396 has mechanical lifters, can anyone confirm?

I am assuming that Crane Cams will have a stock replacement since they are/were the supplier for GMPP camshafts. You need to confirm your HP rating, the higher HP 396 used a solid cam while the low horse version used a hydraulic cam.

Be aware:

Even though the '65 and '69 solid lifter cams use the same grind, the rear cam journal has an oil groove in the '65 and doesn't in the '69.

A cam wears in to the lifters in a pattern dictated by the running position of the lifters on the lobe. If you change blocks with that cam and lifters, you'll likely have trouble with wiping a cam again. I wouldn't do it.

Federal-Mogul/Speed Pro makes a stock replacement solid lifter cam for your engine(s). I don't have the number.

Comp cams also makes an improved version of it in their Nostalgia series. Makes a few more HP yet still acts stock.

Good point on the block oiling. You could use a grooved cam in the later block, but not the other way around. I also agree it's risky business switching flat tappet cams from block to block...but it can be done if you take a lot of care.

If you use a '65-'66 grooved cam in a '67-up block, you'll need to modify the rear cam bearing (solder the single oil hole closed and drill a new .062" hole 180* from it), or you'll have a major internal oil leak and reduced flow to the lifter galleries.
