How many on here run a locked out dizzy on the street? msd pro billet

Don't recommend it...Been there done that...

I ended up having mine worked on so there was about 15 degrees timing at initial and full in by 1100(ish). This was on an MSD billet unit.

Worked like a champ.

I ran the light blue and silvers before with black bushing on my old setup but some swear by the lock out and some say kickback issues can bite ya being locked out!

mine i locked out but i use a start/retard box

I run straight locked... it works. BUT , I'd rather have a retard too.

5 years locked at 36degrees. Never a hard start condition. Guess I got lucky.

this is whats confusing? says no locked out timing in summits webaite then look below ...

These MSD Three Stage retard controls allow you to retard your ignition timing in three different stages. You can activate one retard for a nitrous stage, and another at top-end in high gear for more mph, and still have another module left over for dual-stage nitrous systems. When activated together, the retard amounts are cumulative, so you get the total of the three. For example, if you pull 2 degrees, then 4 degrees on the second stage, and another 2 degrees at top-end, the total retard is 8 degrees (2+4+2=8). In addition to the individual retard stages, the Three Stage retard controls have an optional start retard function that retards the timing 10 or 25 degrees while cranking the engine. This makes starting high-compression engines with locked-out timing, such as crank trigger systems, much easier. These units easily connect to your MSD Ignition and can be triggered from points, electronic ignitions, crank triggers, or magnetic pickup distributors. They're supplied with a 2, 3, and 4 degree module, and must be used with an MSD 6, SCI, 7, 8, or 10 Series ignition.

I thought you were building a race car If you are gona run lots of vert and gear lock it out and play with the start retard if ya think you will need it, You were gona post some winter wedgie adventure in the garage pics its spring

Wedgie, wy would you want to retard a un locked dizzy 10 to 25 degrees, it may not start at all with no advance

yea but summits darn directions are confusing me......

anyways see pic!

Good reason to lock it out on a street car: can't move, one less thing to worry about.
Most common reason to lock it out on a street car: "all the kewl kids do it".
Reason why kewl kids lock it out on a street car: they don't understand what it does (much the same as why they remove the choke, power valve, thermostat, and vacuum advance).

Humm, If my memory serves me right didn't you get all messed up the last time you fooled with your MSD

i like the retard option/locked out I guess the stage 3 directions/summit are vague! see pic above

The 3 retard wires must be grounded for zero retard or just fit a zero pill in the box , i have the retard wires hooked up to the 12 volt side of solinoids , when the noids arn't activated the retard wire/s will be earthed , a soon as the noids are fired off the box will pull retard depending on what pill is in the box , the start retard hooks up to the starter solinoid . this can be 10*/25* depending if link wire is cut , timing has to be advanced 4* when this box is initially hooked up , ran this for a while now with no issues , i use a dial retard instead of the pills , also use two stages out of the three.

Lots of street miles locked out at 12.11 compression and it starts better w/OUT the retard than with it. I have a seperate toggle that starts the car which I use sometimes by cranking the motor over w/the key then hitting the toggle to lite it.Sometimes I start it that way, sometimes not but starts fine eighter way.

how are you pulling out timing in high gear if needed?
