On a pontiac, the factory crank uses a long key, instead of dual short keys like a chevrolet, so you will have to use it in the camshaft. Just be aware that the 987G key will advance or retard the cam 4 degrees. It is advertised as a 2 degree "crank" key, but when used as a "cam" key, it will be 4 crank degrees.

Using your measurements. You are 3/4 of a degree off of the cam card. Check an exhaust lobe and another intake.If they look this good you are done.

Maybe someone who has run that cam and moved it around will speak up.

That is off the same 3/4 of a degree.

I get Intake 109.75 and exhaust 118.25 which is a LSA of 114.

The cam has a 114 LSA and they want it a 109 ICL that is 5 degrees advanced.

Default cam install

well I installed the 2802, must say it runs pretty good after break in.
good vac and a slight lope nothing radical didn't take a ride in it yet hope to very soon, little bit of lifter tick I'm running 1/2 turn past zero lash

what you guys using for for preload I was gonna try 3/4 turn??

this is the method I used

We use the method that Cliff and others here use... We determine how many rounds it takes to bottom the lifter plunger out from zero lash, and adjust the preload to half of that amount. We found with our Hylift-Johnson lifters, it took around 2.5 full rounds to bottom the plunger, so we adjusted our preload to 1.25 turns past zero lash. Different lifters have different travel, so you need to check each application. It's a good idea to run a hydraulic lifter in the middle of its plunger travel.

Please give us some feedback on how it runs after you take it for a drive.

Default lifters

I will definitely try that,, I had a spare and a quick bench measurement was .195 almost 200 thousand

seen this post

If they're 7/16-20 then that's 20 threads per inch. So using simple division gives us .050" per thread (you simply divide one thousand by 20 threads, and you get 50 which represents 50 thousandths of an inch, AKA .050"). Therefore, one complete turn will yield .050" of inch. Your answer is one turn. :yes: And a 1/2 turn will yield .025"

wonder how so many peeps are getting by with only 1/2 turn thats way too little??

Default first ride

well finally got to take the car for a ride,
air temp 55
vac 14 inches
750 street demon running a bit fat
timing 13 static, 21 mech, 10 vac (manifold)
real slight lope at idle
no-ping anywhere
here are my initial thoughts of the 2802 compared to the 068

idle quality excellent
lost 2 inches of vac was 16 now 14 no different in brake pedal feel
power came on about 400 rpm further
068 would start pulling bout 2200 summit cam bout 2600
lost a slight bit of torque not at all an issue just give a little more gas
I can definitely feel a power increase, made 2 runs at my favorite street with mostly farms and straight hardly no tragic
first run dumped the clutch at 2800 or so no match for my 70 series radials shifted at just 5500 rpm and got some serious rubber 1-2-3 forth I was a bit chicken **** and and slowed down checked my memory on my Dakota digital spedo mem and 122 mph and that was in short order I had so much fun doing this that I turned around and did it again.
I had my son in the car which works on the new rice burners with fart pipes. yes his face was white as a ghost and stated he could not believe the acceleration that a 50 year old car has.....
let it cool off with a slow ride back home where we washed off the rubber pasted to the rear fenders of my 11000 paint job

had fun for sure
issues I still have ticks a bit, quiets down a lot when warmed up might play with the lifters again or just live with it.
ditch the carb and put my efi back on after it gets back from warranty repairs.

thanks a lot for all the help guys... honestly I am thankful

How are you liking the 2802 vs the 068 after driving it more?
