1. Forward pattern or reverse? (I.e., are you trying to keep using an original Slap-Stik shifter, or does it have something else that can work either way?)
2. Low-band apply (probably, based on your description) or not?

aftermarket shifter B & M pro stick so either pattern will work and I would think I want LBA but not sure?

Street driven, or track only?

How about making a full list for future reference?
1. Street only, forward pattern
2. Street only, reverse pattern
3. Street/Strip, forward pattern
4. Street/Strip, reverse pattern
5. Strip only, forward pattern, LBA (?)
6. Strip only, reverse pattern, LBA
Should there be 727 and 904 breakdown?
Does HP change VB application?

You could make your own Rev manual using a good core VB and purchasing an ATI separator plate. Using a mill or drill press with an end mill, you can modify the channel walls and reassemble the kickdown valve and throttle pressure valve in the correct orientation.

Otherwise, the Griner 22G05B is the superior RMVB available. Can also contact John Cope and coperacingtrans.com

FWIW I drive to the track and race. I use a Turbo Action RMVB. No problems in 4 years.

I have been using Turbo Action RMVB's on the street since 1997 with no problems. But you need to be aware of what you have and drive it correct. Ron

When my cuda was an auto I had a reverse pattern manual valve body and it was a full street driven car that was also run on street nights at the track. I modified the gates on the factory Slap stick shifter to work in reverse ,worked great.

Munroe's book won't show the transfer plate mods needed to build a RMVB. The pic below shows (in red) the channel partition areas that need to be removed. (1/4" cutter)
For those without a milling machine, a thick steel plate with a 1/4" hole drilled in it can be used. Place the hole over the area to be removed, clamp the steel plate to the transfer plate with two C-clamps and drill out the partitions using a 1/4" drill bit...mark the depth on the drill bit to prevent drilling too deep.

On the main valve body, in addition to the kickdown valve mod, the 1-2 shift valve area needs mods and some components need to be tossed. '71-later shown but earlier is similar.

Turns out the full instructions for converting to manual shift are also on the tech archive
Here . Looks like there is a warning that the transmission will no longer have coast braking in first, I assume this means no LBA?

Is there any drawback to a forward pattern/lba VB? I like the forward pattern on the factory slapstick and don't want to change it.

I always heard the reason for reversing the pattern was so you're shifting away from neutral/reverse instead of toward it

Re: Which manual valve body to look for? - 03/05/15 10:33 PM
I had to regrind/weld the shift gate in my column shift for my mud bogging truck, we routinely shift a ton and that shift into Neutral or reverse sucks.
