you can throw cam specs at us as much as you want, but without knowing your compression ratio and graph of your dizzy, no one will have a clue.

basically:

set timing to 12 degrees BTDC, drive it to a big hill, hold it in 1st at the base of the hill then launch up it. Go all the way through the rev range then change to 2nd and let it go through its rev range. if it pings in either 1st or 2nd, then stop. retard by 1 degree, then try again and repeat in 1 degree increments. if it doesnt ping then advance it till it does, then back it off till it stops.

the more advance you can get without pinging, the more power you get.

If youv got no hills load it up in top gear and see if it pings

yeah good unit. better than the torker cos the inner plenum is shaped to help flow. but bloody expensive if you have to buy one new, so yeah good land.
