what do you think this combo will run?

[82 GT]

I see your point and I understand how you answered it but usually when someone asks what their combo will run, that's usually the number they expect to run.
Then, when they don't run the numbers they are looking for, they rack their brains trying to figure out what's wrong with the engine setup.(regardless of driving abilities)
Maybe the question should have been "What do you think this combo can run?

I guess the bottom line is that the setup is capable of 12's but he's only going to see 13's with his experience and lack of traction.
