That is approx 330-350 crank hp from a 2.78 ltr engine.
Think I first go the dyno with the cams backups 6 degrees and a normal cam setting just for testing and see what the difference is.

Hans already sold the car to a Norwegian guy I think. Regardless, that 75 was a beast!

For idle can you adjust injector end angle or phasing with the EFI you have? In some cases it has helped idle quality and response. I will do that this weekend.

No sequential injection for me...

I'm reducing the volume now after the throttle body wich helps and with a supercharger application where the throttle body is placed in front of the charger, the volume is big.

Here is a crude VVT system. Dual pulley so the tension is maintained.

Saw that one also too on youtube. If you see it running...

Was thinking about the same principle. The only thing with the 12 valver is space...
