L71 Cam and lifters

[David K.]

Hey guys,
I went to my local NAPA this evening to order this cam and lifter kit. The part # for the cam is CS165R which had been provided on previous posts. The nice lady behind the counter could not find the part # for the cam and lifter kit. The lifters part # is AT992. Is this correct for the lifters? Is there a part # for the cam and lifter
kit and if you have it at hand it would be greatly appreciated. I am probably splitting hairs but maybe the kit maybe a little cheaper than each one individually. Thanks for any help.

The Sealed Power part number for the camshaft is CS-165R. You can buy this camshaft for less than 125 bucks from Summit Racing.

The lifter part number is AT-992. You can get these from Summit for about 80 bucks a set of 16. So, you can get the cam and lifters for about 200 bucks. I know of no kit but if there was one it would probably cost about 199 bucks.

Re: L71 Cam and lifters

I don't know if there is a "kit" either, but suggest you try napaonline.com. Put in the year, make, modlel, engine, and then search engine parts. If there is a kit, you should be able to find a part number.

Re: L71 Cam and lifters

Just looked it up and part number CS165R at NAPA is listed at a little over $200 and shows it includes lifters. The people behind the counter at NAPA should be able to confirm that.

Re: L71 Cam and lifters

Michael, Thanks a bunch. Maybe I had the part number for the cam and lifter kit the whole time and didn't know it. I'll check with the local NAPA later today.

Re: L71 Cam and lifters

Joe , Do you think the CS-165R cam from NAPA is as good of quality as the 3904362 or the 143 GM cams ?

Re: L71 Cam and lifters

Original GM cams cast from their own manufactured blanks are long gone. If you buy from GM what you get is a Federal Mogul ground cam (to the original GM prints) on a blank manufactured by the CWC division of Textron... in other words, the exact same part... probably for a much higher price.

Re: L71 Cam and lifters

Thanks Duke . I bought this cam in the early 80s Do you think Federal Mogul was making them then ?

In my opinion, no. However, the GM #3904362 and 3863143 are long gone so, except for NOS at some ridiculous price, they're really not an option. I don't think that the quality difference is enough to justify paying BIG $$$$$$ for an NOS piece.

I highly doubt it. At that time, I believe the GM cams were manufactured in-house at the Tonawanda engine plant or the Bay City, MI engine components plant.

Re: L71 Cam and lifters

GM began shedding parts manufacturing operations in the late-eighties and it accelerated through the nineties. Today, many engine parts that were made in house are manufactured by vendors such as Federal Mogul and Dana Corp, and all parts whether for vintage or current production engines are built to the same quality standard from GM supplied prints.

The only sure way to tell if the cam was manufactured by GM or Federal Mogul/Dana is to look at the ID number. If GM manufactured it will have the GM ID number cast into the blank. If not, the blank will contain "CWC" an other data.

I have absolutely no reservations about quality for replacement parts in any brands that are manufactured by Federal Mogul or Dana.

Some GM-manufactured cams did use "CWC" blanks. The GM blanks (i.e. with "GM" and casting number) were primarily used during the period when the cams were used in PRODUCTION. After that time and for many years GM continued to make the cams but used the generic cores. Apparently, it was cheaper to make the relatively low volume SERVICE cams from generic cores rather than continue casting the specific blanks. For example, the 3863143 cam was last used in PRODUCTION for the 1966 model year. The 3904362 was last used in PRODUCTION for the 1971 model year. GM continued making the cams long after that time but, at some point, switched to the generic cores.

GM might still manufacture some of the Gen I small block cams from generic cores for SERVICE at their Toluca, MX engine plant.

Re: L71 Cam and lifters

Didn't read all the posts. In my area I have found that NAPA is not the place to go for the Sealed Power/Federal Mogul cams.
I use CarQuest just because I have been going there for an eon and they are my pals.
They will order the cam and lifters with no difficulty.
Now to be demeaning against the NAPA store. I got there at least once a week for other items. John
