I have a TFS stage 2 that i only used for a little bit and changed it for the stage 1, I liked them both. If you still need a cam i still have my stage 2 for sale.
I run the tfs stg 1 with 1.7's and afr 165's on the stock 91 shortblock with no problems. I've heard the performance gains from 1.7's is only like 5hp. I'm running them because i got them brand new and free from a friend.
I was daring and did it. Stock bottom end with E7s, 1.78in, 1.55ex, not milled to my knowledge. I know I shouldn't flat out say it will work like that without having some measurements. In the end I took the 1.72s off since I felt there was no point lifting ported stock heads that high.
