interesting, i do have some spare blocks i can do this with to make sure. precision shims is where ive been pointed to in the past so that seems to be the go. the cwc cam i have is fresh and unused so id say ill be closer to the .140 as you say. thanks.

ahh nice. close enough to 10:1 is good for me and a street vehicle on 98 here in aus. as for the cwc there are so many contradicting opinions on them, some hate them some have no wear issues. mine has the oil holes on the lobes and will only be using higher zddp oils, and seeing as i have a kinda sizeable selection of cams and heads to replace it in case it does go bad, i might run it and see how it goes with some careful break in and good lubrication. now to source some lash pads and get it set up right. thanks as always.

thanks mike, will look into it. I thought id be getting more around the 10.2/1 compression mark with the flat tops, might be worth my while to use the a87 head i have to bump up the numbers. I know this has been discussed at length in other topics. yeh my cwc cam has no markings on the back at all so im assuming a grind by a small local shop maybe, but it has much wider lobes than all the stock ones i have, including a "C" cam.

I have a U67 Head I bought a couple years ago now. Its nicely serviced and port/polished with a CWC stamped cam. Im assuming it has stock springs and lash pads as they are way off and will need attention. But im just in need of some answers regarding the specs of the cam or where it came from. It has very little info stamped into it. From front to back of the cam it has stamped. -EP30 1.5(im guessing this is rocker arm ratio) -CWC -C2 D2 -J6 31mm base circle, 39mm lobe lift Totally understand this may be a stab in the dark but any info would be appreciated. Aiming to put this on an l20b with l28 flattops, u67 head (i do have an a87 as an option), electric s2 910 dizzy, twin 45 dcoe in a s1 bluebird. thanks as always.

Any chance you still have an image of the jig you made to cut the release? Trying to work out the angle of the cut.

Will do, thanks. So prompt around here.:)

Raising this topic again, again, again. Trying to sort some ka24e pistons for my z24, did we end up finding if the small end and pins are the same size for the z24 and ka24e rods?
