My motor is a procharged efi set-up blowing thru a highly modified mefi /502 mag intake. I built twin fuel rails, bored out the throttle body and ported the intake. I dynoed it both N/A and blown. It made 650 hp on the dyno N/A using CMI headers but turning no accessories at the more generous 60 degree sae factor that most dyno shops use, Smitty
