Hello folks I have a problem I hope someone can help with. I installed this can today http://www.cranecams.com/?show=browseParts&action=partSpec&partNumber=10005 2&lvl=2&prt=5 and installed a 3 way double roller chain (cloyers). When I installed the new timing gear I was told to install it using the factory specified timing mark (factory ketway) looking that the specs for the cam, was it right? Once everything was back together I tried to start it with no luck. I pulled the valve covers back off and noticed 2 bent pushrods. I don't know if I adjusted them wrong (too tight) or if I installed the timing gear wrong. Any help would be great. Thank you

Ok a few things here. I used the cloyes timing chain and make sure you read the directions they are pretty clear as to what to do. Just put it on the key way and then line up the mark on the cam sprocket (factory setting mark) with the crank sprocket (factory setting mark)
Those two marks should meet. The cam mark at 6o clock and the crank at 12 (not the keyways the timing sprocket marks)

How did you set the valves. YOu must pre set all the valves before firing the engine. The vlaves should be set useing THIS method. I used it and it worked so well no valve adjustment was needed when engine was fired. Also check your timing to make sure it's in spec. Don't keep crankin the engine without it firing you may want to recoat the lobes now just in case you really don't want to deal with cam failure!

Late last night I remembered that I took a picture of the timming gear when I installed it. I looked at the picture and I installed it with 4 degrees advanced. Not the factory specs like I stated earlier. When I bought the double roller gear the parts guy showed me which way to set it. I just could not remember and I though it was the factory setting when I posted first. I was sure the line the marks up exactly, crank at 12 and cam at 6. SO I know I did that right, I just think that it is either the 4 degrees advance or valve adjustment problem.

I have to find my box and get the instructions for the timing chain. I think it was the circle that was stock and then there was a tri. and a sq. Normally you just set it right to the factory setting because the cams already come with 4deg. built into them (search around here will tell you more about that)
Then when you have that set use the method that comp. cams had there to set your valves and you will be good to good as long as your timing is in spec.

I think I have my crank 180 out. I had it at TDC, but I think I may have rotated another 360. I did match up the marks cam at 6 and crank at 12. I am going to pull everything back out tonight and re-check the TDC. Thanks for the reply.

Not all timing sets for the SBC are marked to be set at 6 o'clock and 12. My Lunati billet set is 12 and 12. Turn your engine in the normal rotation direction and watch your intake and exhaust valve/lifter events. Make sure the #1 intake has just closed and the piston has come up on compression when you reach TDC on the pointer. Once the intake closes put your thumb over the plug hole, when it stops pushing air it's pretty close to TDC and ready to fire.

Yes but he got the cloyes set and I get the same thing he does so im going by that.
