I would suggest getting a cam that brings on the torque as soon as possible and has as flat a torque curve as possible too. Since type 4 engines loose life span when rev'd high, a good torque producer is the way to go. As for brand.......any will do.

John the lower the number the more 'bottom torque' ....so lower than a 272?
You can hide what I know about cam profiles under your thumb nail....

In that case, it is time to increase your knowledge base on cams. Along with them, heads, valves, rocker arms, springs all play a part in how well an engine will work and for how long.

John, the heads are the big valve 914 2.0 ...so thin with valve size that most crack even normally...stock new. And bigger valves kills velocity so I use good stock ones.
If I double spring the valves I just make the engine work harder to operate..so just good singles.
The rocker arms are the 2 part sets with no small center spring and have the large adjustments nuts.
Don't really have enough money to do any lite trick rods, pistons, crank work....
So I am down to the cam, and most of the joy comes from a solid launch...so a bottom end torque gave me a 272* ...the longer/higher the duration the more horse at high rpm...I can go to 300....Stock is 270.
So last time I went 272* and thought with the years of experience at PP....maybe some one has a better idea before I close the two halves of the motor together.
Still more than willing to read, take a class, heck I'd wash parts in a machine shop, just to watch somebody good.

John I meant to add that I live on an island where gas is another 75 cents higher than mainland.
When I drive on the mainland I add a touch of advance and go a little richer on carbs to celebrate
the $20 savings on fill ups and give a touch more go to the right pedal. So if I change compression I restrict my octane towards about $5/gal at home...for what amounts to a small jump in performance...net gain...not a lot.
Don't do the club racing anymore so spending more on engine just to catch the guy in the yellow car went away with my brown hair.
best, Steve

I did a webcam 494 with dual valve springs, chromoly retainers, stainless steel swirl polished valves, euro pistons, and 8 mm exhaust valve stems. At approx 3400 rpm it revs pretty quickly to the rev limiter around 6k. Strong midrange.... If I did it again I would do stock valves, heavy duty single springs, keep the aluminum pushrods, and do light weight rods with stock euro pistons. I think that would rock..... Also do a clutch, the stock one doesn't hold very well with this setup!

Info on the 494 (and other common Web-Cam grinds) can be found on their website:

Web Cam Inc. - Performance and Racing Camshafts

For the 494, they say:
Quote:
Lift I/E: .465/.465 Duration I/E: 280/280 Duration@.050" I/E: 244/244

Designed for increased torque with added RPM performance. WEB CAM mechanical lifters required. See part #00-265.

Dave, I have come to discover you are amazing.
I was reading the $900 /914 re metal thread and again you were spot on the items to 'watch' for while wading in rust.
I am after the best launch, from the stop sign thru 3rd gear; after that I just want cruise mpg at the Shell station. bh912e wrote a much nicer check than I can and for a (I think) different requirement behind the wheel. I am inclined to lean towards John Rogers "quick torque and flat curve" ...but I'm still on the steep curve learning.
Thank you, Steve
