thanks for the reply gnbrett do you know of any gns in the low nines with a 200r thanks in advance
Extreme Automatics, CK, PTS would be my choice. Otto and Bison are good to....
Many have been 9.50s with the 200 and a couple have made some low 9s hits. I do not know of any that broke at that level but were replaced by a 400 in fear of breakage. With that being said if its street car that will see an occasional mid 9 hit I would say thats all good. If its a track car with no street duty 400 would be better choice.
Thank you all for helping makeing up my mind the car is stage 2 276 cubic in on center with ac and I drive it alot on the street so it would be most on street but the track is about 30 miles from me and would like to drive there and put down some mid 9 second passes and drive it back home ,the quest for speed and a streetable car is allways a problem but any way thaks alot for all the help.

I have a TH400 w/t-brake and drive it on the street a lot. Solid roller cam, Stage II on center W/stage II heads, yada, yada, yada...and have taken it on 50+ mile round trips. matter of fact, I accumulated 3000+ miles and planning on a freshen/rebuild this winter. I also have 3.91 gears and 30" tires. I say TH400 and don't look back.

Also he does all the trans work on Red Armstrongs GN and his 2004r just went 9.36@146 with a lock up at Norwalk!
That's pretty kool that u drive urs that much on the street. Problem is u cant go over 60-65 mph without rpm's going too high which wastes a lot of gas and puts strain on ur motor. But then again, with ur motor & gears urs could likely withstand the abuse at a higher highway speed. Most motors may not tho.
I'm not totally against the 400 and may switch some day but for now the 200 stays in. If ur not breaking the 200 then it makes no sense to switch and add weight imo.
Brett his car is fine cruising at 3000rpm. People that build cars with $15-20k engines in them dont care much about fuel economy. The 400 has much better gear ratios for an application like his and his car will likely run 8's at or under 30psi. Also the 400 doesnt have to release anyhting to upshift. It just applies the next clutch unlike the 200 that has to release the band. Also the direct drum in the 200 spins backwards in 1st gear at about 2.5-2.7x engine speed depending on converter slip. This is not a good thing at 7500rpm.
