Did you set the base timing with the CAS and DSMLink?

[slowbubblecar]

I don't think resetting it will do much. You have dsmlink set to invert cas? It could be the wires if it is a misfire.

The only thing I did was plug in the CAS and then switched the wires on the coilpack, and turned off Random Misfire.

What do I need to do to set the base timing?

[Shane@DBPerformance]

You need to time it like a 1G. Hook up a timing light, go into DSMLink and turn on the ground timing button, and adjust the CAS so that the base timing is at 5 degrees.

I'll have to go out and buy a timing light. But thanks for the help. Also I have adjustable cam gears could those possible have slipped? If so do I just line up the arrows like normal?

I think the fact that the intake temps were 160 degrees could be a big part of it. But hopefully sometime this week I'll get a chance to work on it so that I can stop speculating and actually do some investigations into it.

Also what should my ARP Head Studs be torqued to? I want to check them also.

Ok just did a quick pull of the spark Plugs and a compression test.

Here is a picture of the spark plugs in order from passengerside to Driverside along with there compression. (done while motor is cold, spark and fuel disabled)

#1 - 180
#2 - 170
#3 - 190
#4 - 170

Oil level is normal, Coolant level is normal. However these spark plugs have 7 runs down the track and then 18 miles back to the house on them and look how White/Black they are.

I"m going to have to build a leak down tester.

#2 is definately having issues. You might want to do a hot compression test on the engine to see what you get. I would also swap the plug wire to see if it is arc'ing.

[slowbubblecar]

wow, that is pretty shitty compression for being a new block.

[SlowWhite]

Jet what do you mean by swap plug wires/Arcing? Do you mean swap the wire that coincides with the spark plug that's "Black" to see if it's just that wire that's bad? or what are you talking about?

[slowbubblecar]

I am pretty sure he means put a new wire on that one (black) to see if the spark plug wire is causing the problem. He doesn't mean change the order.
