What happens here

The discussion continues with the Lotus 29's engine, a 256 cubic inch Ford R V8 carbureted engine with Weber carburetors. The speaker points out unique features like extra head bolts, differentiating it from standard small block Fords. He explains how this engine propelled Ford back into competitive racing and discusses its evolution, including later turbocharging by Offy and Foyt engines. The segment also highlights the extremely compact and lightweight nature of the car, weighing only 1,100 pounds fully loaded, compared to 1,500-pound roadsters.

Goal: Understand the specifications of the Lotus 29's engine and its performance advantages.

era that weighed around 1500 pounds. And they took a variation of their stock 260 V8 block pushrod engine with carburetor. Well, this is a 256 cubic inch Ford R engine with Weber carburetors. It looks like a standard small-block Ford , but it has extra cylinder head bolts down there. Yes. Is that where the R comes from? I'm not sure where the R came from. I only know that it's the designation. But I've been doing some research because the standard small-block Ford doesn't have these cylinder head bolts down here. It's only in this top row. It's interesting. Yes, I don't work much with standard engines. I'm only in contact with these modified ones, but this really brought Ford back into the game. You know, at that time they were also developing the GT40. And then they turned to the four- cam and four-cam engine, and in the four- cam and four-cam engine they changed the intakes and the exhaust. They had what we call the snake bag escape that came out. So, it simply had better airflow. So, in a way, they shortened everything and that engine dominated. It won in 1965 with Jim Clark for the first time and then was continuously developed into an engine that Ed Pink ended up working with. Is that the engine that A.J. Did Foyt end up watching? Yes. We saw one of those engines at the Speedway Motors Museum. Where you mention it's like a hot V design where the manifolds come out through... Yes. In here. Yes. I know exactly what we 're talking about. Yes. So it worked with natural aspiration for a few years. He won a couple of races like that, and then, in the late 60s, early 70s , they started turbocharging them. The Offy began to recover, and the old Offy design is the engine with the most wins in the 500, and it is a turbocharged inline four-cylinder engine . Well, then he started pushing Ford's four-cam engines , and then Ford said, " Well, it looks like turbocharging is the way to go." So they started turbocharging the four-cam Fords , and then Foyt basically bought all the machining, all the rights to that engine, all the blueprints. And then he put his name on the engine cover. So we can see one of those in the museum. We have a couple of them. It will be great to see them. But yes, this is one of the Foyt engines. This is just ... Does anyone remember Dan Gurney as the Gurney Bubble, the GT40, because he was a taller guy? How the hell do you get into this car? It's not
