67 Barracuda Notch with 273

My '76 Pontiac Ventura has a 260 cubic inch Oldsmobile V8, Rochester dualjet carb, all original 38k mile car, rear end has either 2:41 or 2:56 gears, I can't remember which one, but it can't spin the tires to save it's life, going up hills is sometimes a challenge, and passing on a 2 lane road requires planning a week in advance. Real nice car for cruising, rides and drives like a new car, but so completely gutless. I have a 350 Rocket 4 barrel, but my wife has always been resistant to me making any modifications to it. I remember driving a '78 Trans Am around 1980 or so, it had a 403 4 barrel Olds and an automatic trans, had to have the 2:41 rear end cause it probably would have had a hard time outrunning my Ventura.
