She's originally a 289 / 4-speed car that has had a 351W (.030 over) put in.  The drivetrain is out of a '69 Mustang Mach 1.  I've done a bunch of mods.  The forged internals are balanced and were given slightly more slack to allow for higher revving.  Due to the closed chambered Windsor Sr. heads and the forged Arias pop up pistons, I now have a ridiculous 13.5:1 compression ratio.  I would much rather be around 11:1 but maybe I can change that when I finally decide to stroke this 351 out.  I'm running a Lunati Billet solid roller cam .666/.641 lift w/ Crane roller lifters, Comp. Cams springs, titanium retainers, locks, girdled so on and so on.  I'm running a Victor Jr. intake and a Holley 750 double pumper HP.  Also have a 175 shot of NOS that has yet to be used.  In the 9" rear end, I have a posi with a 4.10 gear ratio and 26" x 11.5 M/T ET Streets to put it all down.  Future mods will be 1 3/4 inch primary tube headers that go down to a 3.5" collector so that I can run 3" exhaust w/ dumps before the axle.  I currently just run open headers since she doesn't get out to the street that often.  I plan on changing that.  Also, (obviously) need a paint job, who knows when I'll get to that.  Later on down the line, I would like to stroke the 351 out to a 408 or so.
