timing trouble-help needed

[ghostracing]

hey everyone -once again im having some issues putting the rest of the engine together. last night i finally got my sr head back from the machine shop and decide to mount in on along with my new cams (brian crower 264's).im lost though when it comes to the timing, i put everything back on except for the cam gears because im trying to figure out where everything is supposed to line up. i couldnt keep the cam gears ziptied to the chain like i originally had planned because than i couldnt take the head off. so anyhow, now im stuck and lost as hell because i have no idea where to even start at. i did though set the #1 piston @ the dead top. alll help is welcomed and very much appreciated. -thanks

Check this out: **This is taken from Enthalpy's site**

1.Set crank to top dead center (TDC)…2nd mark from the left on the pulley. With the #1 cam lobes facing away from each other.2. Remove tensioner.3. Look at the front of the exhaust cam. You will see that there is a pin that locks the cam to the gear. You will also see a dot stamped into the cam gear at approximately 1 O’clock. This dot is used to mark tooth #1.4. Starting from exhaust cam tooth #1 count (clockwise) the number of teeth until the top surface of the head. The head should be between 8 and 9 teeth.5. Adjust cam position as necessary.6. Find the DOT on intake cam. Once again this is tooth #1. Count COUNTER-clockwise to the top of the head. You should find that the top of the head should be between 4½ and 5½ teeth. Adjust as necessary.7. Count the number of chain pins between the 2 dots across the top. You should count 20 pins.8. Install tensioner. Rotate engine 2 full turns and slowly bring it back to TDC ( #1 lobes out) 9. Re-inspect cam position as listed above. Repeat if necessary.10. Install CAS according to FSM procedure.

then,

thanks alot Gramentz-- about that chain guide on the top - ive been hearing alot of people say that its better to just junk that piece--tue or false

[Gramentz]

I haven't heard of ditching it...I used it with my built setup. I would bolt it in.

ya a lot of people get rid of it and some dont it doesnt really matter its just whatever you prefer..its not needed..so bro do you understand the timing now? just make sure the #1 piston and both cams are at TDC and make sure you have the right amount of links in between each cam gear dot (10 links/ 20 rollers)

[Gramentz]

And make sure the CAS is installed correctly. Have heard a lot of people putting it in 180 degrees off...

Is that even possible?

[ghostracing]

i think i understand the timing- right now the number one piston is tdc but the cams are not. so what your saying is that the little slits on the gears should both be @ 12 o'clock?

[ghostracing]

wait what is the cas? and one more thing does anyone know the number order for the camshaft caps or brackets? i want to make sure i have them in the correct order

[S13FASTBACKSR]

yes it is possible to install the cas at 180 degrees off and the cas is the crank angle sensor also known as the camshaft position sensor..its the thing that slides under your exhaust cam gear, it also has a gear on it..and no the slots on the gears should not both be at 12o'clock only the exhaust one..the int. one should be at 10o'clock..both camshafts first lobe should be facing outward, away from each other..the cam caps sometimes have numbers on them but if they dont there is no way of telling..but there is a certain sequence you should bolt them down in do you have a FSM?

[ghostracing]

damn that blows- i bolted them down yesterday i didnt check for a order jus a torque it was like 8-9 lbs and i tightened and loosened them i might have screwed it up a little-damn

[S13FASTBACKSR]

you probably didnt screw anything up but it just helps to go with a in out pattern do you know what i mean? not just from the first cam cap to the second to the third..start from the middle cam cap then the one next to it then the other one next to it..and the fsm says 7.3 ft lbs iirc

[Gramentz]

I don't think it matters entirely on the order of the cam brackets. . The arrows obviously point towards the front of the engine (timing chain location). IIRC, there are two brackets that are bigger than the rest; one for intake cam one for exhaust cam. Those bolt in the back, farthest from the front.

[S13FASTBACKSR]

i agree that it doesnt entirely matter the order but none the less you shouldnt bolt the first cam cap down the the second, third etc...you should start from the middle and work your way out just like you would an intake or turbomanifold or just like you would criss cross when putting a wheel back on..and as far as the cam caps arrows ya they all have the arrows but i noticed that only some have numbers..i had a spare head one time with stock cams and cam caps and it had the #'s for what spot on the cam it goes but my current head im using, those cam caps dont..dont know why only some do

[Gramentz]

Yes. Definitely start in the middle and work your way along it so that it seats evenly.

hey everyone thanks for the advice i appreciate it-- anything else before i go and possible blow up my car lol

[Gramentz]

Yes. Double check and triple check everyyyyything before you go to start it.

[Sabot]

make sure you build oil press before you start it.

i dont kno how i wrote that in there twice lol -- thanks every1
