273ci--a keeper in my 64 Dart GT 4-speed?

I would keep the 273. These motors rev!!! Here's what I run in my 66 barracuda original 273 4bbl.Me and my late son went through it. The block .30 over 0 decked all arp studs and bolts. Milodon pan, pump 10 1/2 comp lunati bracket 2 cam crane gold aluminum rollers rockers, lots of head work eddy air gap 650 double pumper Mallory ing.A883 trans 83/4 with 3:55 sure grip. This thing hauls some serious ***. This summer were gonna take it to the local track and get some numbers. Most people think I'm not being honest when I tell them it's a 273.LoL just my thoughts
