how can you tell a turbo crank? i have one original turbo motor out of my monte also i have 2 4.1's and 2 other 3.8 also are there any heads that do a better job than others?
Like I said, just what I heard. However, I also have a set of 4.1 heads and a set of 3.8s. The 4.1 have a larger dome area (visually). I may be missjudging them though as far as their flow rates. Just my 2 yen. I'll leave this subject to the rest of you.
