727 vs 904

been drag racing with the same 904 since 1993.....it has been rebuilt twice in this time...once because the rear spraq was taken out due to the ring gear breaking...

also I have been using a transbrake in this same 904 since 1994.....the trans is in my 69 barracuda ....

also have a 904 in 71 dart that is listed below...again...working on 4th season...transbrake...

I rebuild both of these trans the last time..so they are not some high dollar tricked out trans....
