did you keep the balance shafts? did you put in larger valves? did you use ARP studs?

yes i kept the balance shafts...valves were reground(polished) and no ARP yet.

I do have one issue though....the thing vibrates and rattles everything....any idea what it would be? seems to run fine, but just vibrates the hell out of everything, I dont know if that is because of the cams or what...what do you think?

The cams arnet that aggressive so they shouldnt cause much more engine shake. Is it definately a shake that increases as the engine RPM does? IE is it definately the rotating assembly causing it to shake? Have you checked all engine and tranny mounts? Maybe bring it to the shop to see if they can tell what it is? IE maybe they made a mistake and didnt balance everything properly? Is everything bolted up tightly to the engine?

[Oldsman]

if all the mounts are installed and tight and it shakes a lot.

pull it and pull the pan off and check rod and main bolts. if nothing you can see then take it back and have them rebalance it.

oh one last thing..........hows the timing? maybe your timing is off a little.

[Oldsman]

so you didn't go really all out. just a mild build up. thats cool.

[AnderbrA]

Yeah, not going to wild with it.....ok heres an update, it still vibrates pretty bad.....everything is bolted up fine, the thing that does concern me is the breather tube coming up that circulates the exhaust back through the intake smokes.....a lot more than usual. Could it be a timing issue? I thought the timing was adjusted by the computer itself?

[Oldsman]

timing is set with the cam dowel pins.

as long as you have the cams timed correctly then the computer will adjust.

[AnderbrA]

How am I going to know if the cams are timed correctly? Would that cause it to shake and smoke through the breather tube

[Oldsman]

if the cam timing is off it could cause a shake and screw with the engine.

to check cam timing, remove timing chain cover, belt, pulley, mount. by hand rotate the crank around til the timing mark on the chain gear on the crank and the mark on the timing chain housing line up (@ 12 o'clock) then you should be able to slip dowel pins into the timing holes on cam gears. they should slide in and out easily.

that is just one place i would start.

[AnderbrA]

damn.....you want to do it for my Scott?

[Oldsman]

lol................sure bring it on out.

[AnderbrA]

im just tired of fkin with this....lol it just should work
