I have a 1968 mustang coupe 289 bored out to a 302. It has new pistons, rocker arms, racing cam, (the block was redipped?), it also has a 650 cfm holley carb, and a eldabrock air gap intake. I wanted to know how much HP it has? just a guestument???????

Well,

You can't bore out a 289 to a 302. You can change out the crank and rods, pistons are the same, from a 302 into your 289 block to make a 302. If you’re going to go to all that trouble I would just stroke it to a 331 and be done with it

Without heads and knowing the cam specs, I wouldn’t count on more than 280-290 hp with the info given.
