I am not doing anything half assed. I have just made the determination to use my 77 280z Cam, because input from the crowd for or against was never answered. I also think it is erroneous to use the cam towers from the 280z head and not the cam tower from my P90. The P90 has been shaved and I am certain my N47 has never left the block. Everything, rockers, lash pads, and cam will be used from my 280z engine. No one (still) has answered what adverse affects if any what my "A" cam will have in this turbo motor using the stock ECU. My 77 engine has less than 94k on it and the cam looks like brand new. I will put permanent marker on all of it and roll it over to check for wear.
I took my f'ed P90 cam (that "Francisco" sold me) last night, oiled the P90 towers and the cam spun over in the journals, it was a little tight but I also wasn't done tapping and tightening.
