I keep seeing SL6 A727. What I have in my 1980 Dodge is a Loadflite A727 w/lockup. I am pondering dropping a small block LA V8 into this truck. Will the trans bolt up and work? TIA

No. The bellhousing is completely different between the slant six and v-8 versions. You will need to get a v-8 transmission if you want to put a v-8 in your vehicle.

Wise choice. If you are looking to free up some horsepower, consider switching to a 904. If you get one form the 80s it will have the wide gear ratio gearset that help heavy vehicles like pickups get moving from a stop.

Reed,

I don't want to swap trannys tho. The one I have is like new.

I still need to solve this flat spot off idle. How would you go about troubleshooting something like this? Once I get past the initial stumble everything seems right.

After I get that sorted out I'm going to rig up cold air ducting and install an electric fan. Should be worth a little more power.

Sounds like your pump shot (accelerator pump) is weak.....
with the engine off, take a peak down the throat while giving it a quick pump.
Does it look like someone turned on a fire hose? or is it weak.....

Yup, what Ted said. Check the pump shot on your carb and also verify that the vacuum advance on the distributor is properly hooked up and is functioning correctly.

Ok thanks gents. Hopefully I'll get some time this weekend to look at her.
