Hey guys quick question. I have an 02 gt slighty modded. HV3, 4 inch cold air intake, prj wires, 2.5 zzp down pipe, 180 thermostat, slp resonator with dynomax mufflers, and a 3800 performance race computer. The motor now has 150k but i still wantt more power while still trying to save some money. i was either thinking of getting the gt1 cam from zzp or doing a decent top swap butting leaving on the same heads. Any ideas?
