[Trackrash]

Thanks, guys. I like the vintage 8k 1970 tac I now have. (It's one of those that has the factory tac adapter).
I can't imagine autocrossing or tracking a car without a rev limiter, so one is mandatory.

So my options are:

I can have my tac rebuilt and add an MSD rev limiter. $

Or use a MSD rev limiter, and a MSD tac adapter. Will that work with my tac? $

Or I can use all MSD stuff for even more money. $$

So what is the drawback to just changing the crank gear and everything I have now works with the '74 distributor I have on the shelf at home?

Thanks,
