Exclamation Cam Failure !! .. Solex Upgrade ? STORY

Upon reinstallation of my cams and going to set the Chain spacing I was able to tourque the drv side cam just fine w/ no problems to the 110ft lbs. I was using a crows foot 46 and .... i know what you all might say... a 17mm wrench w/ a Cheetah pipe Firmly attached to it..

As said. The first one went on fine without Any problems. it was a Very smooth tourque.

I began installing the 2nd cam nut and tourqed it to 85 using the same procedure and then went to the next step of 110 ft/lbs

Everything was going just fine and smooth having one person hold the cam from turning while I was tourquing w/ my snap on to 110 and another watching the procedure to ensure all was looking good. ALL of a Sudden!, SNAP! The END of the CAM just Broke OFF! . . AND Silence filled the shop as we all were Extremely perplexed and set back by what had just happened.

Retrospectively I know the problem areas that caused this to happen and its My own fault to some degree...

1. On my previous rebuild I used an Air gun on the Cam.. which could have put a hairline crack.. not recommended thus going to do a better job this time

2. Not oiling the Cam and nut

3. Not stepping up the ft/lb in 3 increments

4. Not using the correct tool, which I now think distributes the proper Load on the end of the cam

Pics to COME. .. ..


So.. What seems bad may actually be a benefit. I am hoping.

What I mean is , now that I am in need of "a" cam Im considering replacing them w/ the Solex cams..

Id like to know All the things that need to be done to my engine in order to use this setup.
I have a 2.4T with Webers. The heads have just been sent back from JB and 10 thousandths were taken off All factory spec heads. The intake and exhaust valves are OE and Im running a .25 base gasket, leaving 15 thousandths. I also have a set of 2.2 t Cams that are usuable for regrind or trade up. Will it be necessary to have my rocker arms resurfaced if I install a New or Used Solex ? I also understand I will need to do some different jetting to my carbs, which Im not too concerned with. Is there anything else that I am missing?

What kind of HP gains will the Solex bring to the table?
