WE just have to have a good SOUND track of the NEW thing going by at FULL song next year.     As well as the great idle sounds this V-6 thing will make when it gets beat on with This BIG BUMP STICK

Well the engine is coming along

That, is going to your place.

That looks like the Geelong road to me

That is a gnarly cam.  The most radical I have seen based on just looking at it.  A question for you guys.  If this cam was going into a bike, the next logical step would be to fabricate a nice set of racing megaphones, possibly reverse cone, in order to get the best performance.  Megaphone exhausts are very rare on cars.  Why is this?

[RidgeRunner]

Usually in N/A applications megaphones will trump straight pipes and headers will trump megaphones.  Headers need more cylinders to work and cars usually have more cylinders than bikes.  Always exceptions to keep us thinking.

Just to clarify, it's the Y-connection or collectors in the headers that make them superior. The pulse from one exhaust stroke is used to help extract the exhaust from the next cylinder in the firing order.

It looks gnarly, but you have to remember it's a roller cam designed for a roller base lifter.
Because the base of the lifter is a roller and not flat the cam profile is different because it is not lifting the lifter from the edge of a flatish surface but from the radius of the roller. Similar to that Indian cam and rocker on Lars's page that Rocky posted

Gnarly dudes, the cam was handed like a baton to the Colonel at the DLRA meeting on the weekend....there is a way to go yet on the motor...I've sussed a way of making the little mod we need to change the cam thrust plate arrangement so as to use this later style cam in the early block....

There were some interesting developements at the club meeting on the weekend......One member has found a dry lake that looks to be a very promising prospect.

It is called Lake Omeo and has a small town called Benambra on the shore,it has a general store , fuel and a pub, perfect! There is enough room for a three mile track and by all accounts the local shire( municipal authority) are keen to see it happen.....it is used as an occasional runway...the shire are even prepared to do surface preparation if that is at all necessary...... or practical for the purposes. This is where some input from those who know the El Mirage surface would be very helpful.

Benambra is I believe about 2000 feet above sea level, it's going to be a tough tow up there.

Can't argue with the location - looks to be between Sydney and Melbourne.  What are the roads like in and out of the area?

Na , not so much between Sydney and Melbourne.... The trip from one t'other is 8 hours for the 550 miles ...to get to Omeo is a five hour trip into the mountains..... a convoluted route

It takes a little longer to get there from Melbourne via the northern route...I've only been up there once , from the south it's all sealed, I'm not sure whether the road has been sealed from the north

...It's a tough tow either way and it's a two lane road with the odd hairpin bend and plenty of blind corners with no run off from memory. I had a very, very near miss on the dirt beyond Omeo back in 1984 ...... fortunately I have mostly sated my apetite for driving sideways on roads in treacherous terrain.......

[wobblywalrus]

Thanks for the info on the exhausts and cam.  Most everything about cars is new to me and I hope you do not mind the goofy questions.

The Omeo lake racing would attract a slightly different crowd.  Probably a lot of bikes.  My wife, Rosie and I talked about it, and the high mountains nearby make it very attractive.

We tend to get a lot more bikes than cars at our meets here anyway

Geez mate, 2000ft doesn't sound like much of a pull. I live at 5400ft & hafta go to 7000 just to get outa here. I guess I've forgotten how flat it is down there & got used to how lumpy it is up here.
