Th400, which one? Rmvb , fmvb Im wondering what th400 to go with,it needs to have transbrake, but Im not concerned about the power limits, but becuase I use my car on the street and want to be able to use it on a ocasional weekend but its mainly my strip car. So I read that a rmvb you cant downshift into second of the drum might explode if it doesn’t have engine braking, but one with a engine braking revs up the engine and when you brake the engine revs high without load which is bad for the engine so is there one that has transbrake, engine braking and one that I can throw into neutral safely by the end of the run?

But what If I want to do a rolling burnout on the street, you have to always shift into 3rd, and engine braking is just more practical, but if there was a transbrake option with a forward shift patern and safe Neutral

There's zero need for engine braking, and I can also do a rolling burnout. But I'm not aware of the type of brake that you are looking for.

The issue with a street driven car and no engine braking in 2nd is the following:
people don't know how to drive them/don't like to drive them when cruising. They'll be in 3rd and they want to drop it down into 2nd and feel that familiar engine braking before they hammer it...that's the "feel" part
When they drive it wrong...they'll be in 3rd and decide they want to do a rip in 2nd gear...so they'll pull the shifter to 2nd, wait a second (even though they won't feel it downshift because they'll effectively be in neutral with the sprag overrunning) and then hammer the gas...this shocks the hell out of the sprag and if you make enough power/weigh enough, you'll explode the sprag. What they SHOULD do, is downshift under power...which is a very hard thing for alot of guys to do apparently. If you're in 3rd, lightly roll into the throttle, then downshift into 2nd, and never stop accelerating. Be on the gas lightly, pull it into 2nd, then floor it.
And game ova...if you're ending your burnouts in 2nd gear...you're asking for a broken sprag. That is a great way to explode one. So to the OP's credit...yes you should always pop the shifter into 3rd before ending a rolling burnout.

Never once did I say that I ended a burnout in 2nd, as I understand how the 400 works. What I DID say was, you can do a rolling burnout without engine braking. Everything else you said, I agree with.

that's why I said IF you're ending in 2nd. Wasn't saying that you are.
LOTS of guys end it in 2nd gear...and everything is fine and dandy for 60 burnouts and then it is the 61st that grenades the sprag...or the 101st...but at some point it's going to go.
Sounds like OP needs to pick if he wants clean neutral ( a totally useless novelty for 98% of the racers that think they need it) or engine braking...i don't know of anybody that makes a VB that does both.
