Odd V8-60 Cam?

I have a V8-60 cam that is labeled as a "twin fire"

A friend who has since passed away told me that he ran it in his midget with a converted lincoln distributor.

I have the distributor and the cam.... I know he swapped to another cam and a magneto later... so I am assuming it was not a 180 degree crank.

From what I can gather without a lot of effort...
the lobes for cylinders 1 2 6 & 3 are reversed, when compared to a stock V8-60 cam... what i mean is...the high piont is 180 degrees, exactly opposite.... but all other lobes are the same when the timimg marks are at the same location....

Does anyone have any thoughts or knowledge of such a thing?

In this photo the small circles repersent the point of the lobe when viewing the came from the back... top row is twin fire... bottom row what I think is a stock cam.

the right side diagrams are the location of the lobes for the intake only... again when viewed from the back of the cam...

all angles are just quick guesses basically showing the relationship to each other... no angles are anywhere near accurate... just the relationship to each other in order is all I was trying to figure out...

Am I missing something here?

thanks for any help or thoughts

I sure don't know a thing about this cam, but I do know that they used to build some reverse rotation engines for use in speed boats. Could this possibly be one of the cams and dist.s for this purpose? Maybe used in racing due to direction of torque?

JWL???????
 
hi they ran the them in midgets firing two cylinders at the same time or what you may call a twin four a lot of torque out of the corner

Right, you would fire 1&6, 5&3, 4&7 and 8&2 together. I've got the same setup, but have never put it in an engine.
 
Thanks guys.... i see i should have looked at a block before drawing pictures... #5 cylinder is first... not #1.... sort of clears things up a bit....

I too agree, must sound pretty wild!

That must have an incredible exhaust note with open pipes.

Zach, you kick up the neatest stuff.

Funny, you would think. There was a guy at an antique tractor/motor show who had a little 60 with one of these double fire cams. Can't say if the specs were the same, but he ran it with one of the V-drive double Wico mag. set-ups.

Looked cool as heck.

It actually sounded like a really healthy four banger.

And that's not a bad thing, but it didn't sound like a little V-8 60.
 
Back in the early 60's I ran 52 Chrysler Spitfire inline 6 in my 46 Ford coupe stock car. I cut the cam in the center and turned one around .180 degrees and welded it back together in the block with stainless rod. I fired 2 cyl to once, 1-6 2-5 3-4 I built the dist out of a marine 12 cyl. dist. Used 6 plugs wires and grounded the other 6 wires. Talk about low end torque. I wish I was 25 again. Walt

Walt, that sounds like pure genius to me! How in the heck did you cook that one up?

We'll I've always been a little crazy but not stupid. I began being engine crazy when I was 14, by the time I was 22 I was shop forman for 10yr's in the first auto machine shop I worked in. I was always stock car crazy so in 64 I built my first one with this Spit Fire engine. I checked all the inline engine for the most power and torque, I almost used a straight Buick but it was to heavy. A friend of mine won 12 Champion ships with a 308 Hudson but those engine were scarce, alother friend won 11 features in one summer with the Spit Fire. BUT, I had to make keep up with my friends. I bored it .125 and use Chevy pistons, they stuck up over the top .070 so I put them in a lathe and chopped off .035 on the top. They popped up .035, I ported it as big as I could, I used a dual carb intake and split header from an army truck. Then I did the chopping on the cam. I could keep up with my friends as long as I was going straight but I had a couple of small kids and couldn't afore slicks so the corners gave me trouble. But I had fun while it lasted. The next year a build a cheaper car. 36 coupe with an 8BA, fairly stock. I always had more engine than I could keep on the track. I didn't last long in that sport, couldn't aford it. The kids needed shoes. Walt
 
Unfortunately I know some who never shared your viewpoint about the shoes; you made the right choice. Merry Christmas Walt.
