My motor was dynoed at 453hp. Now that it is installed the motor revs fast in park. When in gear had you give it a mash of the gas no real power increase. This is hooked up to a 727 with the stock torque converter out of the slant 6. I have a new tci converter do you think this will help?????

 

Should....TCi 5,000 RPM stall.. And a 250 Shot of NOS... Now your flying!!!

Now give us the rest of the story.....
Welcome to the site....

No..Really... Whats the problem? Whats it in? What was the main Plan or goal you were looking for?

 

It's in a 72 dart! I was just wondering if it was possible the stock converter was locking up and holding back power. Thanks for the welcome!!! This is my first mopar

 

What Rear Gear dose it have in it?

 

355 suregrip posi

 

Needs a 3.91 Min..... Just to start out with.....

 

Where on the Dyno sheet (RPM) did that motor make 435HP

 

5100

 

Sorry it is a 904 not a 727

 

Isn't a 3.91 step for a street car I drive on the highway to a lot of shows. Only running on 26" tall tires

 

I'm Going to say Ya'll Need start out with at least...
3500 Convertor...
3.91 or 4.10 gear...
Depending on what your going to do with the car?
At the moment I'm going Street Car Hot Rod... Unless you tell me diff>

 

I just got a 3500 stall from tci they suggested that with my tire and rear end. It acts as if there is no kick down cable . Is there anything else I should look for?

 

Ok...Street Car... Now I'm with y'all...
Thats a bad deal...If it dose not have the detent linkage,,, it will burn up the trans, Unless the car has a Manuel valve body in it.

 

 

It has it and it's hooked up it just acts as if it not there. Shifts great just driving it normal

 

Thanks for the advise!!!!!!

 

ok...So when you drive it... Were dose it shift at?
1-2nd gear should hold to about 25 mph (Normal Throttle) and then your 3rd gear shift should be around 35-40mph

 

I would say that is real close I haven't drove the car in a few months .

 

No Problem on the info.... Your welcome...

Try making the detent tighter... lengthen the rod about 1/4 longer And go drive it. See if that helps...

 

Did you get this motor ready to run?
What did you set the timing at for the Total?

 

It could be something other than the engine/trans/reared. Could be sticking brakes or a frozen bearing or u-joint, I'd put it up on jack stands and check that everything rotates freely. I also remember reading that a 6 cyl torque converter behind a healthy 8 acts like a high stall to begin with, I think it was a low buck racers trick.
