TH400 LS1 conversion...everything you need This will convert any LS1 into a very fast and reliable setup.
*TH400 just recently built by Fernado at Transmission Physicians with a RMVB and awesome Hipster transbrake.
*B&M megashifter. I added a B&M T handle with the button ( I used it for the line lock)
*aluminum custom mount plate for B&M shifter if you have an M6. Mounts to rubber boot holes and then shifter mounts to it.
*T56 center console, B&M shifter fits inside perfectly
*stock LS1 flexplate
*Lokar Th400 dipstick
*B&M stacked plate 28,000 gvw tranny coooler with custom 2000 psi braided lines with all An -6 fittings
*Autometer tranny temp gauge
*M6 crossbrace that allows bolt up of Th400
*precision industries 4200 converter made for the LS1/Th400 combo. No adapters or special flexplates needed. I went 1.38 sixty foots with this and it was begging for more. It also allowed to run on the highway at 2900 rpm at 55-60 mph.
Your not gonna hurt this setup with an LS1 and it should provide solid performance for a LONG TIME
A steal at $2400
I will throw in the driveshaft for another $200. its a PST custom made 3.5 aluminum made for the 12 bolt and Th400. It may have to be shorted up to 1/2 inch if you use a 10 bolt. Not too sure. But that cost about $60 to have done.
If you want to purchase the DS seperate it will be $300
I went 10.2 at 129 with this setup with a cam only (228/232) stock longblock and pacesetter headers and LS1 intake and a 140-150 shot making about 460 rwhp. The drivetrain was begging for more power.
On motor making about 330 it ran 11.6 at 115.
The conversion can be done in a weekend. Add a few days if the DS needs to be shortened.

I didnt miss it one bit. And you know how I was about the 6 speed. The manual valve body is great..and youll LOVE a transbrake. I would bet youll lop of 4-5 tenths easy on spray Mike. best of all...no breakage and very reliable pass after pass.
