Dial indicators are used extensively on snap-gages, throughout the machining industry for tolerances down to at least .0001" It's much quicker and highly accurate. I've used them for years.
The real nice ones yes, but a standard indicator (like the one pictured) is only good down to .0005. The crappiest mics out there are good to .0001. I'm not seeing the logic, I guess it's just faster with a DI...

it's possible that whatever information you've learned from books doesn't correlate exactly to what actually works for the hands on mechanic. for example, you have to separate accuracy and resolution when it comes to mic's and indicators. a given mic might only read to .001 (i have a couple of Starret's that way)but with great accuracy. an "experienced" user can read that mic to within .0001 the same goes for dial indicators. stretch guages like the one shown are far superior than using a given torque value for critical components like rod bolts.

A Mic that measure to 1/10th of a thou is useless in the wrong hands, a stretch gauge or snap gauge takes the user's "feel" out of the equation. They are a very accurate measuring device that can be used quickly and consistantly. A Mic with spherical anvils could be used, but the stretch gauge would be just as accurate and much faster.
Unless you are in a temperature controlled environment, measuring to 0.0001" is futile, the size will change just holding the mic in your hand too long. AL...

What are the cubic inch rules this year?

Have you tried flowing the head with the intake, and carb?

No I did not have time to do that yet would like to have that data but I would like to be on the dyno in 2 weeks(good luck with that LOL) and I still need parts..... and need to finish the other head and match up the intake. I will give it a shot(flow intake/carb on the head) What did you think of the flow #s ? This is now a 2.08" intake valve so if it did not back up over .650" would be darn nice head. I think it would make big power on all out Drag engine.

Not to Hijack your post Brett, but I figured I'd introduce myself here before the EMC in October. Our team (SKMFX Engine) has been accepted and myself being a Mopar fan have chosen to enter a 471 low deck stroker. All I really want at this point is to not embarass ourselves! I truly cannot wait for October and the chance to meet you and the other competitors. I am sure it will be a humbling experience to say the least. J.Rob
You will have a good time!"Nervous Excitement" How far you on the engine build?
