My 91 formula pulled 243rwhp 337tq at the rear wheel with mufflex 3.5" catback stock manifolds and stock dual cats. Also new TCI trans, no smog equipment, and 1.6 roller rockers. What kind of power has everyone elso made. Going to dyno this weekend with new AS&M SSrunners and ported plenum/base and AFPR I will post the results.

 

On my 92Z, when I still had the L98 in it, I had changed to the Edelbrock manifold & runners, along with Trickflow heads, SLP headers and the various things like a 52mm TB, MSD ignition ... This was with the stock bottom end of the block including the stock L98 cam. Feb 98 at the dyno it pulled 271 rwhp / 345rwtq. This was good for 13.4's @101 at HRP in summertime heat. Not too bad for stock cam and short block. I had intended to change the cam and re-test, but never got that far before wanting to step up to another level.
