They were definitely available. However at the price compared to the setup I currently have, it was apples to oranges. Much more cost involved in building a new gen iii hemi and swapping that in than what I have. Trust me I nerded out and did a full blown Excell spreadsheet of costs for gen iii vs LS. LS won hands down. Thus I started the LS swap on jt snd jt germane me a chance to engineer some thing to do something, that at the time I had only ever seen mentioned twice. Never actually saw any really info on making it work.
