Is it a definite that you need to reflash the PCM at the dodge house when you do a swap?
I have a cam head tune from hemifever currently. He wouldnt give me a definite answer in the emails if his tune covers the parameters for a 318 to 360 swap.

I guess this question needs to be answered first.
Thanks for the help guys.

 

More cubes means it's gonna want more gas. Need to find out what the base tune Hemifever tweaked to get to yours. If it was for a 318, that may be the problem.
