Doing a search for 700r4 will net you 130 hits. I did the conversion from a powerglide and don't regret it now that it's over. The two main issues were cross member and drive shaft length. I went with a custom after market x-member ($140.00) ouch! I was leaning towards the 2004r to start with because it is more of a direct bolt in but was swayed away from it by some local guys that didn't know what they were talking about. The 700 has a 3.06 1st gear that will really get things going but then goes to 1.62 for 2nd which seems a bit much, the 200 has a more consistent ratio progression (if that make sense). You must be sure and use a lock up converter with the 700 especially if you go with any amount stall. As far as rear gear I'm leaning towards a 3.55 (2.56 now) which would net a better launch ratio than a TH350 with 4.11's. All total I spent about $1,500.00 that included all the goodies such as x-member, shifter plate conversion, electric's for lock up, etc. I'm no skilled mechanic and managed to get through this by myself with standard hand tools and a trans jack. Go for it... you'll love that overdrive.
