Jeep Strokers

In the process of degreeing my cam ,it turned out to be about 5 deg of what the cam card calls for (105 ,should be 110). I think I am going to machine the cam sprocket for an offset bushing like Hesco uses.
How close is close enough? Plus or minus 1 deg? 2 deg?
Also, what is the proper way to measure chain slack?
I have about 3/16 to 1/4 in if you push the chain toward sprocket centerline and 3/16 when you pull the chain away from centerline for a total of 7/16 in. I have seen 1/2 in as the limit but how is it measured? Total or just 1 way deflection?
Thanks for the help

Hi, I would make sure the cam and crank is exactly inline...before you start machining.maybe you missed by a tooth, . My cam ..comp 68-232-4 was only off by a degree. Did you use a dial indicator to get tdc or did you eyeball it. I have the double roller chain and just went out to the garage to measure the slack. Its against the back wall so I can only get a good measure on the top run but I have 1/8 inch in either direction for a total of 1/4. My cloyes chain and gear set had 3 keyways on the crank gear to allow me to advance or retard by 3 or 4 degrees. It had a square cut/round cut and pointy cut. I would have assumed the square cut was stock since the keyway is square but they wanted me to use the round cut for stock degrees..hope some of this helps

Upon installation, the chain should be fairly tight. Deflection should be approximatly .125.

The deflection is measured in one direction, and 1/4 inch is pretty normal. Also, if you missed a tooth you would be off a lot, like 13* or so. 1 or two degrees would be an issue with the cam or timing set.

You might want to try another timing chain set. Every engine I have built, the timing chain has been tight.

Same here. The FSM states this:
Installation of the timing chain with the timing
marks on the crankshaft and camshaft sprockets
properly aligned ensures correct valve timing. A worn
or stretched timing chain will adversely affect valve
timing. If the timing chain deflects more than 12.7
mm (1/2 inch) replace it.

Even if it is a little less than 1/2 an inch I would replace it since that is cheap insurance against possible failure.

Recieved a new Cloyes set today. I am going to try it out in the next day or so.
I almost had myself talked into using the loose chain, but just couldn't do it.
Also working on a Teflon thrust button setup. If it turns out I'll post up pics.
