I had a 6 speed and swapping to a TH400 I consider one of the best mods I ever did..... If you can believe that....

I didn't really care about losing the highway driving... I had wanted to turn my car into a weekend only local cruiser anyways.... The Th400 and 4400 stall converter ate up all the choppiness in the cam making the car WAAAY more driveable... it was a big hydraulic roller.... I enjoyed the car much more with the TH400 and you can absolutely RAPE 6 speed cars off the line even if they have 250 more hp than you.....

With 650 hp on tap on a 150 shot of spray the car was ignorantly fast.... 1.52 short times and 10.40's@131 on the smallest jets in the kit (150).... that was leaving on the footbrake with a little 355 H&C...

 

Yes beating 6 speeds with gobs more of HP is kewl. My car prob would dyno 520/40 hp and ran a 10.47.

 

thanks that helps alot guys, i think i will give up my freeway driving for probablly half a second faster E.T.'s and wheels up launches........also i streetrace alot and even with VHT 26x10x15 ET drags it wont hook on the street.

th350 will fix that problem.

 

ok you sold me, but know how come u went with th400 i thought the th350 are alot lighter and just as strong?

 

how long has the 383 been in for? how is the rear end holding up? im fixing to put my 383 in next week and am very curious as to how a stock 10 bolt holds up.

 

I'll stick to my 4l60E running 10.47's. I enjoy OD.

 

another vote for the TH400....I am running a 700r4 currently...the TH400 is heavier but it is a stronger unit. The benefits to the th350 is it is lighter.

If I can get my raceweight down to the ~3200 range I will be putting a powerglide in mine when the 700 gives up the fight.

 

it didnt hold up long w/ slicks and 1.5 60' i've allready broke it. but it did last a year or longer just racing on the street. good luck

 

You better hurry before some of us step into the nines on you


Damn 4L60E non-believers

 

lol.. its amazing how many people are running that fast is this trhead alone.... All the LSx boys should take a little look.

The thing that I have seemed to grasp was the fast that build the car before the motor. You can run 10's with H/C and some nitrous no problem.

I am going a little different route than that of you guys. Tc76MPS good for.. well.. who cares..... lol... im going for the times. Im starting with a stock motor, th350 leaving on a T-brake, and suspension and seeing what I can sway. Motor will come when the LT1 go's to a better place (very quickly after I start to whip it im sure =D )

 

thats a nice looking lt1 car! im hoping to be right behind you with a mid 10 sec pass in my lt1 car.

 

thanks for the compliments guys, i cant wait to yank them wheels

 

no matter what anyone says the TH400 is a stronger unit than a Th350 with parts being equal.....

Can you make a strong Th350? Yes... Will it be as strong as a similarly prepped TH400? NO..... I went with a TH400 cuz I'll have room to grow... and now since I'm setting up my car to run 8's with around 850RWHP/1000RWTQ the TH400's strength will come in handy... hell i don't even know if the Th400 will take it..... I might go with a glide if the 400 explodes....

 

thats a very good way of looking at it, does anyone know how much lighter the th350 is than the th400?

 

anybody have a better 60' than 1.59 on 17's or faster than 11.2?

hahah lol i might have the record for somebs like that.

 

lol.. who cares.. make a record someone cares about!

 

like building an 88 fullsize slammed to the ground

 

personaly i think its cool when yhe truck can out handle the car. Plus it has a 97 vortec 350 with a blow through demon soon getting a turbo... and 20's.

then i have the 96 T/A with a Tc76MPS bolted to er...

Lets not forget teh 1970 Firebird with a big block...

Least my **** dont look JSUT LIKE EVERY OTHER CAR ON THE ROAD!!

but if you really feel like making up records to make yourself feel better.... go for it. But even so, I sitll dont think you would have the record on that...
