Lobe Lift .380 (in) .375 (ex)
Gross Lift (1.6 ratio) .608 .600

Duration@.050 lift 236 248

Lobe separation 110

Diff ration is 3.54:1

Car runs 17" rims with Toyo 888 tyres 315/35

Have adjusted ignition to give total of 34 degrees total timing and about 16 initial.

I would sceptical of the dyno.
Coincidence the torque/hp peaks are so close numerically?

Something is wrong, exhaust, carb etc.

Any more engine details Keith?
