For the life of me i can't understand the reasoning for the cam manufactuers doing this. Just make it straight up. For a stock engine,
Some people CAN'T read, STOCK parts. Who said anything about after market parts, besides any John Does car comes in for a rebuild, whatever it is will be flat rated and out the door no cam degreeing no anything, get in the real world please. Machine shops can't compete with the sweat shop builders now poping out small block chevys for under a grand complete with 3 year 100,000 mile waranty, do you tjonk thdy degree a cam,heck do you think any of the big 3 degree their cams? It is a waste of time but you do it your way and the other 99.99% there way. Now go give Monte a kiss
Problem is dot 2 dot isn`t always where it should be......... 
For a 318 2barrel it is or any dead stock engine for that matter
Any time you introduce aftermarket parts into the mix, you run the risk of parts not being machined or stamped correctly.
I always degree a cam even if its a stock rebuild!
Dot to dot does not cut it! 
Thank you............as Monte said; Some may actually run well once they stop "ASSuming things are correct.

Doesnt matter what they say it is, it is what it is. Degree it to what it should be.

i degree'd it to 111 and the @50 specs don't match whats on the card. that's why i asked how to check @50 op/cl.
Maybe this will help..
268/2= 134-111= 23 BTDC
Check to see if that's what the intake is set at..
You should be good to go then..

Once you have the tools (cheap!)it's a simple process to do it every single time!
8* is 1 tooth on the cam gear and may be easier than adjusting the crank gear if it is not made for that much adv.

yes, i set it straight up to see where it was at and get some direction on which way to go. i advanced it with a 9way crank gear A2 slot and get 111.25, but the @50 intake close spec does not match card.
Did you account for the lash or could the lifter be sticking?

one thing that may be an issue is the crank socket doesn't fit tight enough on the keyway. i'v used several of these comp. sockets(Pontiac,sm chevy, bg chevy and mopar) and they all have slop in the keyway. I tried tightening them up with tape, but it doesn't eliminate all the slop. I get about 1* of movement either way.
Maybe if you cut some strips from a pop or beer can and shim the gap in the socket to the keyway it will work better how you want.

That's what I did. Still, gear was misstamped!

ok, I was gonna use a trimmed piece of feeler gage, but i'll try the beer can. i'm second guessing myself because as I barred the engine I noticed the exhaust lifter was on the lobe past TDC, alittle further than I thought it should.
on the opening of intake lobe there is overlap of the exh lobe until after TDC a little.

The wider the LSA, the less overlap at TDC  OP, I have several different degree wheels, I haven't found the perfect one yet  The width of the pointer can have a affect on how they read, as much as 1/2 degree   BTW, I've yet to see a motor that would react to one degree change of valve timing LSA or lobe center timing on the dyno or at the track, maybe the little C.I. motors will react to that

I moved it one tooth to the left and the dang thang line up to the left a tiny bit and degree in where it shoud have been
