Complete Guide to Performance VW Camshafts

[nocturnalcompetition]

I know this is an older thread, but I have a list of camshafts that I can not find any information on, so any help with the lift and duration along with the name that goes along with it would be helpful. Some of these only have a few numbers so it is all the information that I have.

285

340

401

Crane A8

43

20

701

31007

280

32014

280

32014

153

270

V276MB

The next two are Erson VWMT3 but have other numbers and letters under
them

8248 106 683 J
B158 106 78* R

Any help would be greatly appreciated. Thanks guys.

thanks mark, I'll measure the OD of the hydro lifters to find out which they might be.

Appreciate all the input fellas!

I laugh at the Engle cam cards..

The FK-89 is supposed to have .416" lift.

never seen one with more than .400" lift.

Most are .398" out of the box..

It’s an AS41 AE code late case. Lifter bores are Definitely oversized (really thin wall, especially for the later case).

What you have sounds cool! Only ever read about the late mod factory hydro engines, have yet to see one.

The engine I picked up, never heard it run nor did guy I bought it from. Split it open to find bearings just showing copper. Everything nice out perfect aside from needing first cut on alignbore = lucky! Even the thrust is perfect STD.

Will freshen it up. Have an engineer friend that has a cam jig to measure mystery parts/cams, so we’ll know soon enuf. As I told last responder, I’ll call Bergmann tmrw to see if it was his. The guy said “it might be a Bergmann” and the entire long block was painted red (w/valve covers off = all over tops of springs & rocker tips = classy!).

could the case started life as a Mexican ACD engine . they have a hydraulic cam standard and use type 4 lifters .

I've a ACD engine that I use as a spare and want to do a rebuild one day with a better cam /heads etc . and have wondered what the differences are inside to run the hydraulic type 4 lifters .

[Todd Getty]

Thanks! Why I didn't think of Bergmann, I don't know. It's not one of his full circle cranks w/holes drilled in the counterweights, but will call and ask him tomorrow. Appreciate the input and quick response!

many hyd lifters are ford lifters. chevy are .842 and ford are .874

When I hear large displacement/hydraulic cam, Bernie Bergmann comes to mind. His magazine ads had a lot of flashy stuff in them, like bright colored engine tins and Porsche fan shrouds,full circle cranks, etc....

Hello, I realize this thread is old but wondering if anyone is out there to help identify another random cam and/or crank maker(s)?

I recently cracked open a "mystery engine" finding a lot of nice parts inside but cannot identify the crank or cam makers.

Engine was a 84x94, blow through dual dellorto 40mm carbs. 84mm crank was welded & offset ground based on a late model type one crank w/ VW and Audi stampings. It has "ECS 84" stamped on end counterweight and it's also wedgemated to a stock weight flywheel (STD/STD perfect condition).

The hydrolic cam has "4 6853 / P 7" stamping. I marked the lifters order prior to splitting the case, their faces look smooth and reusable and cam lobes do too. I believe the lifters are Chevy type as the lifter bores in case are way oversized plus 6x center shuffle pins, full flowed, drilled and tapped oil galleys & welded behind #3 = "super case" as we used to call them. It had 1:4 rockers and .300" super thick shims under the Mahle barrels. Heads are mismatched, assuming one melted down and was replaced at some point: clearly different combustion chamber volumes and shapes from one head to the other...

Planning on alignbore, all new bearings, new heads and bolting it back together BUT would really like to know more about the cam or crank.

Thank you guys!

the Autocraft 9526: The 297deg is at .050" lift. (not advertized).
It is a pro-stock cam.
Powerband from 5,500-10,000rpm.

What does small, medium and large displacement really mean in cc for air cooled VW engines?

The .050 EC number doesn't work. Too many 1's. Using 10 or 11 the math works.

I too have an old Crane Cam card.

I'll do my best to get things correct;

VW-282-NC clearance intake .04, ex. .06

intake @ CAM 360/407 with 1.13 ratio
exhaust @ CAM 360/407 with 1.13 ratio

cam timing @ .014 tappet lift intake opens 40 btdc, closes 62 abdc, 282 dur
exhaust opens 72 bbdc, closes 30 atdc 282 dur

cam timing @ .050 tappet lift intake opens 19 btdc closes 41 abdc 240 dur
exhaust " 51bbdc " 111 btdc 240 dur
No figures for Crane spring requirements or rpm figures given
Part # 760-0014

You can still get the V-26 directly from Engle.
