THe 4.6 SHort block is the same. The compression bump comes from the heads.

Will adding the top end with heads and all even work because of this?

Yep.

My situation with funds, etc. leads me to look at these posibilities with hope to improve towards ideal in the future. So, my original question is whether or not the Callaway ECU will run a standard Gems motor?
|
When the check engine light is on, does it blink at the rate of once per second? How does the engine run?

Based upon the info I have read the standard computer does allow for some flexibility in components and sensors. All of the sensors are the same. The upper intake is the same except for shorter stacjs and Carbon Fiber tube.
|
Its also ported.

The cam probably is different though.
|
No. Its the same.

The Callaway ECU is different I know with programming and the chips being soldered in.
|
They are not soldered in, they are changeable. However, the transmission is set up differently and controlled by the GEMS computer too.
Frankly, using the PROM from a regualr 4.6...I dont know what will happen. It could go either way.

Maybe it won't work. Isn't it iffy either way I go though? At this point could it be that I have a bad Catalytic converter causing a rich mixture and missfires, etc?
|
No. The cat does not effect mixture. You are runnign rich for some reason under the hood.

Couldn't a bad MAF also be at fault?

Could.

Why did the original Callaway engine throw a rod?
|
Want my guess. I've seen this happen more then once.
The fuel injector leaks so badly that it fills the combustion area.. The piston comes up and cannot compression the fluid and bends the rod. After driving for a while, the bend gets worse untill it cracks in half.
That woudl be consistant with having a misfire like you describe.

I don't know. These components are from that setup though. Is a 1313 code indicating a bad conveter or damage happening to the converter because of excessive emissions?
|
p1313 means the misfire is so bad that it is causing cat damge.
I'm bettin gyour Check engine light is blinking. Am I right?
