Another one from a similar time period…….
SBC 400.
Was in some sort of off road/trail rig.
I don’t know much about it, other than he was friends with the dyno owner.
I kind of got the impression he was thinking he was going show off his engine building prowess with how awesome the power of the build was.
I don’t recall if it was tested with headers or not.
It had some sort of factory heads on it, but not the “good” ones, and he’d done some clean up on them.
As I’m thinking about it, I seem to recall talk of roller rockers and 1.6 ratio.
This was one of those situations where I could tell as soon as I had it running…..it was not going to make big power.
Like the 396, it was also in the 280’s, but that might have been with headers.
Made a few pulls, Played with the timing, swapped a carb, no real difference.
Took it back off.
