hi guys dont know if this is the right section if not can someone move it etc.this is what my goal is.mustang raceweight should be 3000-3200lbs.street driven/track car.i have a ls3 block dont matter if i have to send it out to be resleeved and go bigger than a 4.0 stroke crank as long as i get what i want.i want to run 6.20s or quicker on motor and 5.20s-550 on nos.yes it has been done plenty of times with the mustang but all have power glide trans,i want to do it with a 4speed auto.basic setup is 402-408 with ported ls3 heads have been getting it done with pg trans.i want to build enough or a little more than enough the first time so ill take my time to build it once.my thoughts were ls3 416 dart ls3 heads ported supervic 4150 or 4500tb cam motion llsr and 200r4 trans by extreme auto or 4l80e but dont no if the heavy 80 will run good on the motor all input needed give me ideas oh forgot pump gas or i can mix with 110-112 race fuel
