  3. It was suggested that I start a new thread.
    Combine it if you think that's better.

    the tach you posted needs a sending unit. A tach match will get it going
     
  5. Thanks!
    I just emailed them.
    Much appreciated!

    my Miller/banger OHV conversions will turn higher than 4k RPM, I don't know about yours....
    did you talk with Sean at FSI about your application? He would set your dizzy up specifically for your application.
    also...every Miller style OHV I know about and have tuned need 38-40 degrees INITIAL advance to perform...
    good luck
     
  8. @winduptoy The specs on my car are above. The dist. was recurved for the head by FSI. It runs great and goes faster than I'm willing to go in a 98 year old car.
