Just because "stuff" happens, it may be wise to buy a high quality billet front drum to basically eliminate the chance of a drum explosion. For about $700 you can get a front drum that won't blow up and will probably last a lifetime. Your right foot and trans tunnel may thank you. Expensive, but it sure gives me peace of mind running an 11 sec street car with an automatic valve body and drag radials...

Or you could change out the valve body to one with LBA.
Cheaper and easier to do.

Put in a super sprag... they are suppose to be
bullet proof... if it doesnt blow/roll over the
sprag then you wont hurt the drum

Is there an automatic shifting valve body that has LBA in drive?

I agree that the ultimate sprag is money well spent. The billet drum is just insurance in case it ever lets go. I have both.

The sprag is only engaged in low/1st gear.. so
thats the only time you need to worry about it
EDIT
the stock VB has LBA.... on your question... no

Do you know how much they cost as I would like to put one in mine the next time I pull my trans ? Ron

They are like a $150.... I think

Thank you. Ron

I put a Coan super sprag and LBA valve body in my transmission expecting to drive on the street.

I understand do not pedal in first great and most people start out in second gear. I like to start out in first gear (never free wheel it) I Just shift into second gear and shift 3rd gear. No brakes or line lock. My burnouts are for distance I guess, alway increasing throttle. My car is mostly a street car, track maybe once a year. Trans is build for the street with a lot of goodies talked about above.
440 702 hp and 650 torque at the flywheel. 727 MVB 9 inch tight convertor. New motor has not been to the track yet. So is this way ok for the trans? If I do a brake stand burnout always 2 to 3. Great info guys.
