He's getting great power out of his Kelford 193B cams, which are not on the extreme end of things (but not on the conservative end either).

I wonder why your 7A would run higher oil temps though... makes no sense to me, same oil capacity, almost same engine.
Your oil cooling setup sounds a bit unusual to me, but I'd think it should be effective enough in principle. The AW11 being a mid-engined car, and the cooler being front mounted, you probably have quite some oil capacity. Are you sure you're getting enough airflow through the cooler? If not, it will only function as a heat sink. If your cooler is just hanging in the breeze you might benefit from some dedicated ducting tot he cooler, you ideally want to have a pressure differential across the cooler at speed. If air can go around it easily, pressures will mostly equalize, and then your back to it working as a heat sink rather than a radiator.

I believe those Kelfords will require a better intake setup than the OEM intake manifold. But that's a good suggestion! Thank you

Regarding the oil cooling, the radiator was effective enough with the 4AG, I just think the 7AG is generating more heat, but don't know why. Initially I thought it could be from the fact that it was running a little lean, but now I've richened it up it's still hot @120ºC.
