I do have a question..... but I have to bore you first.
I have recently installed a MSD Street Fire box on my m10. I was quite happy with some improved gas mileage and a little more "oomph" at low RPMs. (or at least it feels that way to me) but I had to set my distributor to 0 degrees advanced any more and it starts to shake at 2200rpm. At first I kind of thought "Because I put on a MSD, its reasons not known to science and I have to live with it" but then I started playing with my Pertronix and realized it messed with the timing advance curve, like a lot. Didn't keep track of the first gap I had it at (it was probably at .050) but when I set it to .030 I noticed I could advance it to 5 degrees advance (at 1,400RPM) without the shakes at 2,200 RPM I kept going till I set the Pertronix gap to .016 (what regular old points want) and got to about 15 degrees advance at 1,400 RPM. (no shakes) its close to what my old book wants for that speed with the T.I.I. distributor. I am now curious if I should dust off my dwell meter and try and set it like points. I cant find anything online to back this up so my Question is.....
Did anyone else notice that with adjusting Pertronix gap? Or is this a weird MSD fluke ? (everybody sets theirs to .030)
Can you measure dwell with Pertronix ?
What degrees advance do you guys set your timing ?
and what do you think I should try and achieve with my m10? (high top pistons, shaved head, weber 38/38, MSD street fire with MSD coil)
