Help . I finally gat a fire lite undeer the machine shop but he was degreeing the cam and was @106 and needeed to get to 108.There is only a key for adjustment.He said he could try to order 10 gearsand see if one got him closer due to varaitions.I suggested drilling the cam gear and cam and puttingin a pin and usining a cam button.I have seareched and haven't found a clear way.Please help soon while I got him working on it,t hanks

You can use the off-set bushings or just oblong the pin hole in the cam and shim the gear in the direction it needs to go.

106 will slightly boost the low rpm range.

Might just want to leave it there

Just a note to clarify Small Block Chevy SBC Bushings can be used for our cams. Is this correct???
Thanks

I believe you can also get an offset woodruff key for the crank. Maybe the combination would get you where you need to be.

Well I went to the motor shop and gave him this sight.We had to have a new keyway cut in the lower gear.We tried a couple of diffrent cam gears but by the time we would have drilled the the motor man thought there wasn't enougn materials to support the bushing.He said there is so much lift/duration and a big cam with a lot of spring pressure it proabbly wouldn't hold up long.I gotta trust him,I just would like it completed.Doesn't look like I'll be taking my car to the Vegas meet.I'm going anyways.as always thanks for you advice.

After my experiences and talking with many people, I wouldn't even think about degreeing at 108. 104 would be my max to start with, and 106 might be worth trying. Performance cams I am convinced that 98-102 is the right range.

108 will give you lazy low end.

I don't know about JP Perfprmance, but Summit has their own brand with a set for a big block with a 3-keyway crank gear. You should be able to use the crank gear and chain and buy a slant cam gear. If it were me, I would listen to Lou very carefully.

This is a blatant high-jack but it's really on topic. I was just sorting out my degree #s and it seems really low. Maybe I'm out to lunch on my procedure. Here it goes. Find true TDC; set up the dial indicator on the valve train; zero dial at max. lift and take a reading @ .050 on either side of 0. Add them together and divide by two. This should be the # I'm looking for. My #s were 45 and 139. This comes out to 87. Where did I go wrong.

_________________

You are supposed to set your dial at ZERO lift and check the degrees at .050 lift.

There are a couple of variations on the theme but here is one method.

According to the Comp Cams method, you zero your dial at maximum lift. Check it out. http://www.compcams.com/Technical/Instr ... es/145.pdf

I'm not entirely sure, but it sounds to me like your cam is retarded by 10-15 degrees. I'm not sure what the centerline is supposed to be but I am pretty sure it should be higher than where it seems to be.

OK, so you're doing the intake centerline method. Fine. Are you checking #1's intake or exhaust? If that's 87° ATDC I think you're a tooth advanced.

I'm sure that I'm at true TDC. I've checked, checked and re-checked for that. This is based on my intake centerline measurements for now. I just feel like one variable isn't in order. I'll play the scientist tomorrow and go through my procedure from the beginning.
