I'll let you know about the head early next week. Shoot me those sketches we talked about. e-mail should be open. Thanks, Ray   [Reply]   [Send Email]

Six rather than five hole injectors and a narrower spray pattern. You still need to think extra airflow. It's easy to flow extra fuel but without extra air. It's just going to make extra smoke.   [Reply]   [No Email]

What else can be done to them? What size G can you run against no mph limit?   [Reply]   [No Email]
