Edelbrock Performer RPM (7577) and 360 Magnum CI heads

Saw your info and was thinking about using KB107 4.000 pistons in a donor 99 dodge 360 magnum for my 99 Dakota rt. Just checked #1 stock piston and it is .044 below deck height. What r ur thoughts on using the KB107, seems to me they will be above my deck height a fair amount...........

I could say go for it. But not knowing what's all been done to your block etc. I would do what Rumblefish said. It's been a long time sense I put the trickflow heads on my magnum 360. But if I remember right the KB107 pistions were right at deck height or a thousands or two below it. I am useing the KB107 pistions with a felpeo 1008 head gaskets. My cranking compression is around 165/170 psi. Here is a picture of my KB107 pistion in my 2000 magnum block
