I popped the heads off in order to remove the broken exhaust studs (one per cylinder)
(I wrote broken head studs....I meant exhaust studs) Stock camshaft has some strange wear patterns on it which might be part of the previous owner problems with the motor. Cam will be a 9600 grind from Rabys old store Intake planned is stock L-Jet, however I can be swayed to install Megasquirt (plenum or ITB) since I already have the Megasquirt. Exhaust is older European Racing Header. |

you can measure the valve travel without even taking the rockers off.
To actually get at the cam to change it, you have to split the case, now the "what should I replace?" comes down to 1 - your budget & 2 - what you find. In either order. You can inspect & measure all the 'pertinents' and decide if anything is worn. |

Oh well, I'll still measure it yet chances are it's going to stay unless that camshaft mentioned earlier would really offer some improvements. |

Jake doesn't sell parts anymore, only turnkey engines. The Type IV store is now owned by LN Engineering.

Saw that one coming 1/2 hour ago. Funny. No quotes required.
Mike, have you tried contacting LN/type4 store directly with the cam #s you have? Does the site list a phone #? Edit: I checked. you should call type4 support |

Jake doesn't sell parts anymore, only turnkey engines. The Type IV store is now owned by LN Engineering. I'd think he'd still have the specs to the older stuff he sold. Cam is not listed on Store website. I could call them tomorrow, might be something not usually offered. |

Unless somebody had their NEW cam read, those details are probably proprietary knowledge.

Mike,
Go to Elgin camshafts and look at what he sells. Lift ramp is most of what you can change . He has one that will work. Split the case, it will make drilling out the head studs easier to jig up. Plus, you cannot replace the camshaft without doing that . |

How long did the motor run with broken head studs?
I would suspect the cylinders are out of round. |

That is the lift at the cam. edit - not even sure of that. The #s look wrong. Is that at the cam or at the valves? While you have his attention, could you please ask what lift he expects with that cam at the valves? |

I called LN Engineering, they found the specs for the cam I have sitting around... Lift: I .335 E .400 Duration: 290 I/E Duration @ .050: I 252 E 254 108 Lobe center. The 290 duration number is odd. Look at the WEB 73 numbers in the link below: http://vwparts.aircooled.net/Web-Cam-Type-...72-p/00-472.htm WEB 73 is a FI grind but IIRC it has bit more lift. If you want L-Jet you need an stock based FI grind like the 73. |
