We are gonna put a comp cam 220 ,224 duration,513,533 lift,get stock heads shaved 25 thosandths,3 angle valve job,double valve springs,studs,guide plates ,roller rockers,case hardened push rods,24lb injectors,and power plus upper and lower intake. The motor is not the original his friend said he thinks it came out of like a 92 t bird.Also the battery is in the trunk cause it was supercharged with a shot of nos.
