4onthefloor, thanks for the info. I am going to try the NP on my original bell housing. I looked up some info on this tranny and found that it has ratios of 1st. 3.09 2nd. 1.67 3rd.1.0 and 4th..73 I don't know if that is good or not but it has to be a little better than the three speed in there now. I will still have to convert to an open drive. I,ll probably go with that nova rear at the bone yard. Thanks for all the info.
