I have a brand new set of stock lifters and am wondering if they will be ok to use in my build with a Scat C35. I haven't heard many good things about Scats lifters, and I'm cheap. :D

If you are worried about the quality of their lifters what makes you so comfortable about running one of their camshafts?

Go ahead and use them :)

What brand of srock lifters are they? There are alot out there, some good & some bad...

If you are worried you could get them SLR treated. BTW - I run Scat lifters that have been treated by SLR, but I am also running one of SLR's cam too.

It was a gift, and I've heard a lot more rants about their lifters than their cams.

I wasn't trying to bust your balls, just food for thought...

I was watching the lifter problem as it grew in several internet forums and never did I see a corporate response to the issue. People were having failures and there was no ownership of the problem that I saw by the manufacturer.

Another high profile company had a problem with some cam gears and stepped up to the plate and dealt with it as any reputable company would.
I have spent around 3 grand on parts from the latter (including two piece lightweight lifter that don't fail) and ZERO from the former.....

I would say not. The C35 is considered a performance cam and it requires performance lifters. A couple of simple, basic differences between stock and performance lifters is that the feet are thinner and theres an extra bevel cut on the back of the lifter. These provide clearances needed for the taller cam lobes. In some of the most radical set ups the lifter bore may even need to be clearanced some.

My own suspicion is that at least some good number of cam/lifter failures have been due to things like this or bolting down 1.4 rockers to something without knowing what the cam even was or if there was enough clearance between the cam lobe tip and the lifter foot. Solids are simply not as forgiving as hydraulics. Thats what the lash is all about.

Heaven forbid, if at some point the cam lobe actually bottoms out the lifter in its bore something very bad is going to happen. Just static checking for some gap at set up time doesn't work either. The motor expands as it runs, the cam flexes, all kinds of really weird stuff happens inside the motor that we don't really see but the tolerances tell.

Ok, call me obsessive but I had to go find the lobe tip to lifter clearance. Acccording to the Mister Berg himself its .040.

I've run stock lifters with Engle 110 and 120 camshafts without any problems. The Scat cam is probably made from the same blanks...

Same here. I'm running VW de Brazil lifter with my CB 2241 cam, and they look perfect after 1,200 miles.

The CB 2241 with 1.1 rockers lifts at .424. My Engle 110 has .430 lift with 1.1's but I run 1.25 rockers so it ups the lift to .501(minus lash). The CB35 has .419 lift with 1.1 rockers. Theres a Web cam thats in this same range but I'm not sure which one is the closest because theres like a 110, 119 and a 163 that have numbers around the same range as the other cams. I did notice something I hadn't noticed before and that is that Web has asymetrical grinds. I might have picked one of theirs if I had seen that before to give the exhaust side of my heads some more help. Unless I do more porting on the exhaust side they don't hit the magic 70 percent flow ratio. Oh well. I think Web even makes a really good grind for my motorcycle too. Hmmmm. LOL. Sometimes its a curse.

I was told to check for a .060 lobe tip to lifter foot gap from my machine shop. I also have Brazilian lifters but I still checked to make sure I had enough gap. Better when the case is open than finding ground up metal later on.

Thanks for the tips guys! And nice to see neil68 on here, I go by kaferman62 on the Club Vee Dub forums.

Neil you say the stock lifters should be ok for an Engle 110 cam. I want to buy new stock lifters, do you know who makes the best ones and what vendor to buy them from? thx

The ones I used were mostly OEM German-made Wizemann (later called Mahle-Wizemann after Mahle bought them out) and OEM Brazilian-made Riosolense (black & orange box).

The Mahle-Wizemann's are quite rare now, although I found some on a German parts dealer's stocking shelves a few years ago...blue box.
