Not trying to revive the flame-fest that the other thread had degraded to, but since there was some inaccurate info posted there... The '03 mach & the '01 Cobra have basically the same shortblock, with the exception of a slight compression increase from 9.85:1 to 10:1. They both have the same forged steel crankshafts, weak cast powder connecting rods & Hyper-u-craptic pistons. Both the Mach 1 & the '01 Cobra are equally as weak (or as strong) when boost is concerned. Hand-built, yes. Better internals? Nope... Not true at all. Look at this dyno graph comparing my stock '01 Cobra to my stock '03 Mach 1 & tell me where all this extra Cobra top-end or mid-range power is: The only thing hand-built about the '01 Cobra was the engine - the rest of the car goes down the regular assembly line, just like the V6/GT/Mach 1 cars... Bottom line - both are great cars & should be respected for what they offer, no matter which one you choose.
