Cam timing Part 2, wierd "stock" T4 cam, JAKE??? Anyone??? too high of lift??? Options

[Mark Henry]

This is my last post on Dylan's original thread, he thought that he installed a NOS VW/Porsche cam in his new rebuild....

Dylan's getting .330 lift at the cam. I measured a new Web 73 and I get .320 lift
On the stock (used) cams I have I get about .275 at the cam, even less for a hydro.

It does have a rivet on gear and I’ve never heard of an aftermarket cam with a rivet on.

I’m at a total loss on this puppy. I’d hate to have Dylan rip out an OK cam, but things smell real fishy.

This cam has me going WTF! (IMG:style_emoticons/default/unsure.gif)

Is it a hipo regrind on a stock cam?
His new engine with stock FI will not idle below 1500rpm

Anyway you look at it, there is no easy or cheap solution to your problem.

Cam and lifters... Ceramics are the only way to go at this moment. Unfortunately the supplier is very slow, Charles (LN) is now getting a trickle of them in, but you will be on a waiting list with at least 30+ sets ahead of you. You would have to email Charles to confirm the wait time.
You have had the engine running, so I would take the lifters out (keep them in order) and look for wear, just to be safe. Do this before before you spend the coin on the SDS.

Carbs may have an issue without headwork, but in my junkyard 2.0 engine with a scat cam that has .430" x 276 Degrees, SDS had no problem running it. The only real head issue would be how long will the stock springs last if you start honking on it.

If you did go for SDS here are the main issues,

1/For FI only (D system) you will have to upgrade your dizzy eventually.

2/For FI/MSD (E system) It's programmable ignition, but you need the MSD box/dizzy.

3/For the FI w/Crankfire (F system) the engine must come out, fan shroud off and you must custom fab the trigger mount.

The "D" system can be installed in a weekend, the "F" might take 3 weekends. I already know Dylan has access to the equipment needed for the install and the more he could do at work, the less time on an "E" install. These times will not be a "squared away" install but it would have you up and running. I can help you a bit if you do go with the SDS system.

The Kit Carlson system is still 4-6months away from production.
