Hey 95 svt...Don't know why but I like your Cobra!! lol
I've got #259 white w/black leather!
You will need a dyno tune!
I've got the AFR 165's and A custom cam. My idle would surge like crazy at first start....and stall all the time!!! Don't let this worry you at all!!!! The dyno tune takes care of all of this! Go with a adj fuel presure reg, when you do the h/cam swap,then you be able to adjust fuel presure when you get your dyno tune/chip install!
I've done all you have and much More! Any more ?'s just ask!!
