I wanted to post a question on timing and hear the response. A month or so ago, I had to change out my MSD distributor, a mechanical advance with the 18 degree stop and the light blue and light silver springs. It was worn out. I replaced it with a new MSD distributor, a mechanical advance, with the 18 degree stop and two light silver springs.
Since making the changes, the motor seems to run differently. Now, with that being said, I did back the timing down from 18 to 16 initial, at the advice of the person that built the motor with me. So, presently, it is 16 initial and 34 total, all in by around 1300 rpm now.
This is my setup:
406
Eagle crank
6 inch forged rods
Stepped icon forged pistons
All internally balanced
AFR 195 heads
Lunati Voodoo hydraulic cam , 276 cam, 233/241, 504/525
Air gap intake
Speed Demon 750 w/annular boosters
Dynatec stepped headers 1.78 to 1.58
MSD 8551 mechanical distributor w/18 bushing, light silver springs
MSD 6 al box
Should be running about 10.4 compression
Backed by a dual friction clutch/TKO 500/12 bolt 3.55 rear
On the top end, it just seems to run out of juice a little and also seems to have picked up a little vibration.
So, if this were your setup, what would you set your timing at?
Thanks,
Rick
