I just finished installing my MSD Crank Trigger that I would like to run at the track, however I do drive the car on the street "once in a great while." My engine is a 440RB with 12:1 compression, with the Solid Lifter cam specs of 262I/266E @.050, with a LSA of 108*, C/L at 105* .600 lift using 1.6 Ratio Rockers. Heads are Performer RPM Aluminum that have been CNC ported by Modern. I am running 12* initial, with a total of 35* all in at 2800 rpm using the MSD Billet Distributor. I am also using a MSD 7AL-3 ignition system that has built-in start-retard. 7in of vacuum at Idle @900 rpm. 430 Gear ratio as well...so, my '69 GTX is really a Strip/Street car vs. a Street/Strip. So, should I just lock the distributor, set the crank trigger at 35* BTDC and drive it on the street once in a while or? Thank you for the advice!

I think you have to lock it out with a crank trigger, the distributor does not control timing anymore.

Lock the dist at zero and put 35* on the trigger... really doesnt matter where you lock the dist just as long as its locked and set it all at TDC then put in 35* trigger ![](/ubbthreads/images/graemlins/wave.gif)

Hi Mike,
The question is, if I want to run the car on the street once and a while, will it be OK to run the car with the crank trigger at 35*?
I do understand that I have to lock the distributor and set the phasing once I get the timing on the CT set to 35*.
With my cam specs, I guess it would be OK to drive the car on the street a little with the Crank Trigger?
Or...should I only use the Crank Trigger/locked distributor at the track? Thanks.

You'll be fine with the trigger on the street ![](/ubbthreads/images/graemlins/wave.gif)

Thanks all for the help! I pulled the distributor, and set it to be locked. I set the timing on the CT/balancer for 35*, and then set the rotor phasing at #1 plug. It started, and runs MUCH BETTER, and still left the 10* start retard chip in as before, and it worked without any kickback or backfiring! Again, thank you all!

I ran my hemi for years w/ about 25° initial and 35° total. Finally locked it out and was surprised how much better it idled. Added a collar to the distributor shaft to keep the timing steady at the same time...better, but not rock solid. Then later I added the crank trigger when I started pulling a lot of timing for nitrous. Love the rock steady timing from the crank trigger.

What is this lock you speak of? I stole the crank trigger from the 499 and have it on the 540, using a MSD for the dist.
How does the MSD get locked?
You put a zero degree bushing in it... real easy ![](/ubbthreads/images/graemlins/wave.gif)

On the MSD pro billet that I have you have to pull the distributor, drive out the lower shaft collar pin, then pull the weight assembly up, remove the weights/bushing/nut/springs, then turn it 180* and drop the threaded pin back into the main assembly.
My distributor is for a RB/440, so collar to remove instead of the lower gear.
Detailed instructions on MSD's site. Not as simple as changing a bushing, but not hard at all either.
