Keith,
You might want to check an earlier post "First time on a dyno". You did not state what your compression ratio was, or if a compression check was done. How many miles since a competent rebuild. Certainly closed chanber heads might help as well as a more aggressive cam. What kind of headers are you running etc., etc. I'm sure you will get a number of responses from very knowlegable people on this web page. Hang in there, there is a lot of things you can do, but the best results probably will come from the proper selection of compatible parts.
