I am fairly new to engine rebuilding... But I rebuilt my 289 in my stang.. I had to bore it 30 over.. i have been told it is now a 293 does that sound right? also I was wondering if you guys might have an estimate on horsepower for the engine being bored 30 over, and it running tri y headers, dual exhaust, 600 cfm carb, 270 cam, slightly stronger than stock valve springs, valve job was done, port and polished heads.. thats all of the infor i can think of now.
