Jamie, you made your decision about your car and your money, good for you. Me, I must be doing something wrong when a guy with a mid 11 second car is convinced based on the opinions he reads on an internet forum that the addition of a crank trigger will reward him with quicker and or faster MPH on the time slip due to "more stable, rocky steady" timing yet I've got about 4000 10 second time slips, 1000 9.0x time slips and numerous 8 second time slips from two BBC combos with billet distributors that every time I've set the timing it too is steady at RPM. Further, the clamp has never loosened, the timing has never changed due to oil viscosity and temp and never in over 2 decades have I had to constantly monitor a distributor for fear of component wear but wait, it gets more crazy...the MSD billet distributor in my 950HP BBC has ~ 18 degrees of mechanical advance in it. Yep, you read right, it is NOT locked out yet somehow, I'm able to make pass after pass after pass where my 60 foots and ETs typically vary thousanths(.00x) on any given day. Guess I'm just lucky or maybe all this talk about more stable timing means NOTHING on the time slip with engines like yours and mine.
Again, Jamie, your car, your money, your time, your decision.
