dimension difference between a th400 and a 4l80e?
where can I find this info? Planning on a auto swap into my twin turbo viper and I know the th400 can fit in the car with minimal notching of the frame rails. someone told me the 4l80e has to have the frame rails moved and a new tunnel made, but I know its not too much larger than the th400.
anyone knows where I can get the dimensions?
About how much wider is the 4l80 than the th400?
I know its not chevelle specific, but I figure its a good place to get the info
