Help me win this argument 400 in a 72.

I think it is all in what you want to do with your car. My 400 is a 73 with stock bore and stock compression. This engine was done on a budget as I didn't have a lot of money and wanted a big block. The engine was ball honed, new rings, full grooved bearings and I used a 383 crank. I have a windage tray, a 509 cam, Mopar Performance electronic ignition, 516 heads and yes they are still running the small exhaust valve (that's what I had at the time). I have an Edelbrock TM6 intake with Edelbrock 750 carb, Hooker Supercomp fenderwell headers with 3 in exhaust and flowmasters. The trans is Turboaction with reverse manual valve body and a TCI converter that stalls at about 2200. The rear is an 8 3/4 with Richmond 4:10 gears. The car has run the best of 12.56 at 110 mph on 87 octane. Tires are BFG Radial T/A's not a drag radial. I drive this car a lot and always has performed. I just drove it 2 1/2 hrs to OC, MD for the Cruisin show. And, I have done that for the last 10 years and the engine has been in the car since 2000. I have never had it apart and to say the least, I have always run the crap out of it. This was just stuff for the most part that I had laying around and really wasn't expecting to keep it in the car this long, but it is hard to pull something out that runs this good and is dependable. So not everything needs to be built to a crazy level to have fun, just my 2 cents.
