I need some input on a 1000hp 727 trans

[mike1965]

I need a recipe on what part's I will need for a 1000hp 727 514ci with a PT-106mm turbo , these are the part's I already have .

- Steel billet drum loaded with the bigger piston
- The Ultra Sprag from SMR
- JW trans brake
- PTC 4000 stall
- SMR Super 2 1/4'' solid super band
- SMR Super duty billet strut
- SMR Rebuild kit with there race clutch's

That's it so far

Here's a link to there site >>> http://smrtrans.tripod.com/smrtransmissionsintro/index.html

Thanks Mike

Rear roller support would be a good upgrade too. SMR has a nice one. Maybe billet planetries too...

I run nearly 900 through stock 3 pin planets and the stock 1965 low roller. I also don't run a trans brake. You may want to upgrade to a steel front planet carrier. The super sprag is a good idea. We killed the stock sprag with a trans brake valve body even though it was equipped with low band apply.

Thanks Doug , I think I should be ok I have a 76 727 core I will build up is this a good core to use.

I will have a trans brake valve body but will not be using the trans brake part of it I will be foot braking with only 8 pi of boost on the street.

Thanks Mike

Is this 76 a good thing or a bad thing , I can get a 73 or 74 core maybe I know a guy who has a few I would have to go trru the pile to see if there is on there.


One another note I pulled the pump out of my 1970 727 that was in the car and I think that someone swapped the pump support out for the wider 71 and up if I'm rite please correct me if I'm wrong .

Here's some pix











Thanks Mike

That support is the later style but it still has an early pump body.

The early kick down servo with inner and outer springs is good also. Remember to follow the trans brake instructions as you may have to drill a hole in the high gear drum. Possible it's there already though. Drill a new vent hole in the rear of the case and plug the front vent. You can modify the front reaction shaft with a cut off wheel ( see CRT website). This isn't a very good picture but look at the right side at the drum oil feed hole. Notice how it ground down to the intersecting hole.
