I read on here somewhere that someone did not recommend using a manual valve body on a street and strip car. Could you please tell me why?

IMHO the manual valve body for a street car would put alot of undue stress on the entire drivetrain. Since the MV does not shift up OR down You must do this. Also some MV are reverse pattern and if something of an emergency happens.... Well you might forget the pattern I had a Mv in my 70 Hemi CUDA and it was a PAIN in stop and go traffic. Hope this helps

I have run manual valve bodies on the street for years.

The reason they say not to is that some do not have a band apply in low gear. If you downshift to low and stand on it you run the risk of rolling the sprag and exploding the front drum. I really don't think this is much of a worry with a Slant/904 though.

If you do run a manual with low apply you will only downshift to low once anyway.

I have one in my '68 Signet. I drove it to work every day this week.
The main reason for the 'Not For Street Use' is most people don't understand how to safely drive a MVB without low band apply or how they function. You can ease on and off the throttle while in low, but NEVER stand on the throttle in low gear while coasting. It's best to only use low gear from a standing start. Once you roll the sprag, next time you run the RPMs up in low gear, the trans may end up on your dash! The failed sprag will cause the high gear drum to spin at 2.2 or 2.45 times the motor RPM, so 5000rpm at the motor will turn the drum 12000rpm causing it to explode.
It also has a harsh shift into second. I just make the shift early, about 5mph and it's not too bad. I never go to low unless I stop first, it lugs around street corners fine in second.
One good thing about a MVB, make all the carb and intake changes you want, no need to fab up new KD linkage, not to mention the extra room for header clearance.

I drive my Cuda on the street with a manual VB. I will admit, if it were a "daily driver" it would get to be a pain in the butt, manually shifting every gear around town. It seems like it is just more inconvient then a stick. Also without the low band apply feature, when in 1st gear and you let off the throttle, the car will coast. There is no engine braking. If the valve body has the low band apply feature, you definatley do not want to downshift from 2nd to 1st, while decelerating. That shift is so hard, it will knock your teeth out.

Which valve bodies have low band apply and which doesn't?

Which does the cheetas have , low band apply or no low band apply?
thanks in advance...Jerry

Most companies that sell MVBs offer both. The low band apply models have only been out 5-10 years. The Cheeta in my car is one I bought in '82 and have used it in 4 different cars over the years. I'm sure Paul Forte at TurboAction has a MVB with low band apply.
The reason for rear band apply is to help support the sprag in the rear of the case. The reason it wasn't used for many years was to eliminate 1-2 shift overlap. If the rear band is applied in low, it has to release at the same time as the second gear band is applied. If it releases late, it drags on the rear drum and slows the car, kind of like the brakes dragging. A no apply MVB can work safely if used properly. The only mishaps I've heard of is from misuse.

Actually they have been out much longer. I had a Fairbanks manual VB with low band apply, in a 727 back in the mid 80's.v It was in a 10 sec. altered wheelbase 68 Cougar with a 440

Growing older is unavoidable but growing up is strictly optional.

I have a Cheetah w/o low apply, and a Griner MVB and Griner trans brake w/low apply. I have run them all on the street at one time or another.

You can tell when your valve body has overlap because the car will drop the nose on the 1-2 shift. Most "shift kits" that bark the tires in second actually have overlap and are really locking up the tires, not spinning them.
