cobras have irs (independant rear suspension) gt and mach have solid rear. the irs is bad for drag racing and weighs more. gives the car a sluggish feel form the start. of course this can be corrected with mods. gt can be som pretty quick cars if you really do them up.
with most of the boltons on the gt and a little weight reduction the gt can be fairly quick. i have most of the mods you were planning and more. car feels good. this spring i was going to buy ported heads and gears. that would pretty much put me in the rwhp of the mach. the car would be flying. even with just gears on mine it should be pretty fast.
however somthing came up so i will be selling the car in the spring.
