Not sure a 94 would perform as well as the 855. I had a 239 8ba with an 855 on it & an Isky Max 1 cam. The 855 woke that engine up noticeably. The 855 developed a vac leak so i went back to the 94. You could tell that the car ran better with the 855. Based on that, i think the 255 Merc would be somewhat starved for fuel. ? Just my 2 cents worth. mike
