ZBAT in Jacksonville, Fl. Did my 906 heads with the new 33 springs in 88. I supplied and they set them up by seat pressure specs from? First spin around the block and all I got was float city! Pulled the heads and shimmed the springs to Mopars recommended spring installed height and a different animal was born. The OP must have had something similar cause that cam can be lot's of fun!
