For Greg. Here are the pics of the clearance work I have done so far, the crank and rods rotate, just got to set up the timing gears and work out which bits of the cam need a little work. It hits just behind the centre bearing.
As said before I am fitting a CB 82mm crank with CB H beam rods.
I actually found that carefully using a belt sander was the quickest way of removing material, maybe my die grinder is dying.

Re: Stroker case clearancing
I'm finally stepping up to some 48 IDA's for the 2010 season.I am also switching to 1:25 rockers with triple valve springs, I removed the flat wound ones when I first built this because I did do some street driving but now it's just a drag bug

You just need short bursts of spins. 30 second spins and check the cut....spins some more and check the cut.Buggsy wrote:Don't buy bits and a die grinder unless you have access to a professional size air compressor. The thirty gallon, one lungers that most of us use to run impact wrenches will burn up before you get the job done. Die grinders consume a huge amount of air.
I do not know anyone that runs the rotary file continously.
Here are more pics..
cam clearance..
I clearance the rods too! That corner of the rod where the rod bolt end can be seen can be rounded a bit as part of the rod balancing etc. It also eliminates the requirement to take large amounts from the cam. The cam notches seem just a bit to deep for my taste. I take it down about half that much and finish the cam with a hand file. Then I polish the areas with a 3m pad on a diegrinder.
