i've converted my engine from solex carbies to efi.

running 9.7:1 pistons, but with later dowelled camshafts (88250). ive got 160 +\- 5 psi on all cylinders. I would like to get hold of the original camshafts (210 or 230).

the cam timing is factory. well factory for those cams anyway. The notches are stright up at TDC compression stroke. I'm thinking i might play very slightly with this to see the effect.

i run premium unleaded and im not getting any pinging. Compared to carbies it has more torque down low with little effect up high.

For a daily driver it is sweet, starting perfect, runs good no matter what the wheather is doing, and you dont need an expert to tune it.
i tune it on the street using feedback from the seat of my pants and the o2 sensor.

you say ignition timing is 5 degree BTDC, i think ive seen 10degrees quoted elsewhere. with my combination i think its a matter of trial and error. Thats why im planning to get computer controlled ignition running aswell.
