SOHC to DOHC possible?
 

Hey guys I'm new to mustangs and I just bought a modified 4.6l 02 GT I know it has a cold air intake, shifter/clutch work, and exhaust work...

Does the mustang typically shut off once it hits redlines, I'm trying to figure out what other modifications might have been done possibly to the ecu etc... Is there anything that I can do to find out...

Also I was wondering if it's possible to use your stock 4.6l and swap the heads from SOHC to the DOHC like with the cobra's I was also wondering if the 6 spd manual trans will bolt up to the motor as is...

Thanks for your time and I appreciate your help, please keep the flaming low :P I know I'm new to this don't need it pointed out :D
