Hi, I'm building an engine for my '66 bus and I'd like to know what cam to use.

My bus is gonna have a long ratio gearbox and a straightaxle set-up and
the engine I want to use is a 1600 singleport.

I'm hearing different things on what cam to use.
Some folks tell me to use a W100 for extra torque at low revs
and others say I should with the stock cam cause that way the engine
will give the best overall performance.....

What is your opinion?
(PS: I'm a NOOB when it comes to engine stuff so please try
to keep the answers simple Laughing Embarassed )

How much port work would you need done on the heads for a 1776 sp?

I would consider oner of the following;

Crower 61000 or 61002
CB Cheater Cam
DRD's 280

If you don't want to split the case, ratio rockers with the stock cam does give you a bit of power. My butt dyno likes the 1.25's midrange over a set of 1.4's.

Just throwing out alternatives.

Ehh for money and ease the Stock camm would be the best choice .
Has it's advantages .
Qaulity Control at the V.W. factory pretty much insure's that the Camm will Degree to the Crank .
Provided Stock Crank is used . Preferably with the Crank it came with if Possible .
Then there's a real good chance or even better chance that the Camm gear will be of the Right Pitch radiuse < if not Find one that is .
How many stock camm's do you have to choose from ?
There is an outstanding Old School article In Bill Fisher's How to Hott Rodd Your Volkswagen on Stock Camm selection .
It seem's that not all stock camm's are created Eqaul .
Urge you to Read it .
I keep a shelf full of used Camm's My self like over 20 or 30 of them .
Mostly for the Gear's .

W100 all the way.
The W series cams have a fast ramp which promotes faster filling of the cylnder. Builds more torque than a stock cam.
And if you wanted, you could use a adjustable cam gear and advance the cam for more low end torque.
Easy choice.

Stock will give you better mpg, w100 will give you a better power range.
If your keeping a stock carb I'd go with the VW cam.

the main question we need to know is what carb(s) are you going to run. Do NOT go over 276 duration with a stock carb, or you'll have tuning difficulties. If you run duals (of any kind) you can run around 286 duration without issue.

So with the stock carb run the W100, with duals run the W110.

John brings up a good point on the fuel delivery associated with cam decisions....How stock will this be??? Will you be using something like a single German Solex 30-1 '67 version (power fuel jet)? 205K distributor, or something else? Both mentioned if you decide won't require more than the stock cam.

It will have a stock carb...

So it's still confusing:

Stock carb + stock cam = best MPG out of the bunch.
W100 will give you the better power range using a stock carb though you will sacrifice MPG... not much though.

John, don't you think a 110 would be far too large for even a dual carb 1600?

That's clear but then again "Almost Alive" sugest using a stock cam...

look at the previous advice of posters to determine the quality of advice they are giving.

Thanks John. Your a charmer.
I stated stock cam would give better MPG's and I would run it.
Prove me wrong.

I don't have to. I'm just saying to the other guy to read the advice and make up his own mind. I never said you were wrong, I simply gave my advice.

Do you think that all advice from all posters is of equal quality? Because if you do not "consider the source" then you think everyone posting on TS is of equal quality. My recommendation to make up his own mind on the quality of the people giving him advice, was NO SLAM ON YOU. Stop being so defensive.

My advice stands.

Because you changed gear ratio's I would strongly suggest staying with the stock cam in a heavy Bus

not trying to highjack the thread, but i'm about to buy a cam for my
1600sp also. i have 1.25 rockers, heads have valves back cut, cleaned up
ports, and 3 angle valve job with single hd springs. i'm running ICTs and
a 1 3/8 header with single quietpac, also have a SVDA distibutor. i was
thinking of getting the w100, scat c25, webcam 218, or the cb cheater
cam. i dont think all of those will work with my ratio rockers though so i
was leaning towards the w100. what do the experts suggest? thanks

oh yea, its a 67 bus with 4.35 tranny with staight axle conversion on
205/60/14 tires
