So in diagnosing what is wrong with my car im at a loss. i guess this should have been one of the first things to ask myself though.

will a cracked head lead to a large lack of power? and can it mean no black smoke? (alda removed)

i feel like i should still be able to get some smoke from it (if my head is cracked) because the black smoke is from over fueling correct?

A cracked head will "generally' not manifest itself in a loss of power. The crack does not typically lower the compression in any cylinder to the point where a power loss is noticeable. The crack does allow oil to pass to the coolant or coolant to pass to the oil. This is undesirable due to the coolant having a detrimental effect on the journal bearings over time.

There are folks that can run a cracked head for 50K miles or more. The performance is not seriously affected and they simply need to add oil and/or coolant. The longevity of the engine will definitely be affected in a negative way.

The removal of the ALDA may not result in excessive smoke if the driver is not a complete fool with the 603. The only place that smoke will be apparent is from a dead stop with your right foot mashed. Once the RPM's come up...........the smoke disappears. The smoke is not apparent from the driver's seat. You would need a vehicle to follow and observe.

also, you may have still intact either the trapox, or the cat in the exhaust, it'll limit the black smoke (and power potential) from alda removal...

thanks alot guys. i figured that a cracked head shouldent ruin everything. i think after i swap in my new IP, injectors, and get it timed up it should be better.

even when i TRY to make it smoke there is none. had people watch absolutely nothing.

also. there is no trap oxidizer on my car and i have an open down pipe.

also. fuel filters are both sparkling clean, i checked / replaced both and checked the fuel tank strainer, that is not the issue. and also ran my car out of a by pass fuel tank that fed right to the engine. still the same issues.
