The GT 40 ran the 427 side oiler, which head a wedge type head.
The SOHC was based on the FE block like the side oiler but had HUGE heads that had a single cam in each head.
Here is a 427 side oiler
Notice the difference in head size.
No I was talking about the ones used in 1964 and that era.
Why was the single overhead cam version banned by Nascar? Was it not available on production cars?
Nice piece of engineering! I used to run 351W in my race cars but would bore and stroke them to be 408 to 410 Cubic inches. The weight difference between the big block 427 is over 120 pounds more than the Windsor, and the 351 Cleveland was 80 pounds more,and is why I preferred the Windsor.
