Thanks for the replies, I did in fact read the Frank Mcgurk article several times over the course of the past three months. That being said, that engine was just a bored out 261, totaling 278 inches, he made 200HP, but he was using two single barrel carbs, an old style header, and technology thats 40 years old now. Would it not be safe to say that cams, carbs, pistons, rods, and exhaust have come leaps and bounds since then? would a stroke out not increase HP and Torque to a large degree? People at Clifford tell me no, Tom Langdon tells me yes. Because lets look at the physics here, and yes I have taken physics. You are increasing intake volume of air and fuel, then compressing it all into the same tight little area and igniting it. This increases preasure, IE-PSI, which gives a better and more potent explosion, which should result in increased torque for sure,and since torque and Hp and biproducts of each other, it goes hand in hand. Some things cant be gotten around, like the bad head design, but we should be able to maximize HP elsewhere, "Free up" if you will to crest that 270-280Hp and 350-370lbs/ft of torgue area. Sure the caddy 261 will rev about 500 less RPM on average, but its the 292/250 argument, the 292 works less hard to make the same amount of power, while the 250 must rev higher, work harder and use more gas to make the same power. Provided the two were built identical except their strokes the 250 would reach the same power as a 292 at a higher RPM. Just some thoughts, not to get off topic, but the topic was about the 261 stroker advantage with modern parts, etc... vs a non stroked, but bored 261/278, with 40 year old technology.
