Yes, they sure do. Maybe if more parts were available that didn't cost a fortune, and it was actually possible to get close to 1 hp per cubic inch in my old 235, I might have kept it. But 80 hp was a little too weak.

250 or more hp and 350 or more lb-ft of torque would feel very very nice in that truck, and I'm sure that's within the capabilities of a good 292, especially with an aftermarket aluminum head. And really, that's not that much less than the 350 makes.
