Nicks Garage 383 build

PRH said
The trick would be coming up with a cam that’s big enough to not hold it back too much, but not be so big it’s miserable to live with on the street.

Here they compare these 3 cams in a 383 and the small HR gave the power of the larger FT while keeping the duration of the smaller FT

214/ 224FT

231/ 237FT

214/ 224HR
