Default 260 HP vs 290 HP GM Crate Motors

My '76 El Camino SS needs a new motor. Her 350 (w/ 305 heads) has a dead hole (bad comp rings) & is overpressurizing the crankcase (very messy). She currently has a rebuilt TH350 and a non-posi 2:73 rear end. I have a new exhaust system w/ a new set of Hedman Elite Hedders, "H" pipe, 2 1/2 " pipe w/ Flowmasters. I also have a new Weiand Action+ intake and a new Edelbrock 600 cfm performer carb already on my sick motor. Because of these parts I don't want to switch over to Vortec heads, but I still want the best bang for the buck. Our local Chevy dealer has Goodwrench 260 hp crate motors for $1365 (+ core) and GM Performance 290 hp crate motors for $1745 (no core). The 260 hp motor comes with a 3 yr warranty and the 290 comes with only 1 yr. Is the 290 hp motor worth the extra bucks? My big 2 ton girl sure needs the extra grunt to move her large behind w/ those high gears. Thoughts? I really don't want to throw big bucks into a rig that is my daily driver (sport utility) and barely worth the price of a new Edelbrock crate motor.

Horsepower doesn't mean much ---look at the torque numbers----torque moves vehicles -----unless there is a significant difference save the 400 bucks to use more effectively..........Dan

That 260 HP motor is about 100 horses more than it had when it was brand new. With your add ons ( alum intake, headers, carb ) It should run pretty darn good. Jon
