To all,
While we are on the subject of timing, perhaps you all could give me
your recommendation for the initial timing spec for my tiger. It is a
K-code 289, with the ford dual point distributor, It has the hydraulic
lifter equivilent of the Mustang HiPo cam, and a Holley 600, headers,
etc......
What do you think?
