My.... I did not mean to start all this....i guess the full grooves will be fine...I only spin this engine to 6000 rpm its somewhat understressed,i was just wanting some opinions ,and they all seem very helpful thanks guys...



I watched a program with the late Joe Mondello building a 455 olds engine this weekend and he used fully grooved bearing in it so ya I think you will be safe too. If you do not know who Joe is google it learn about one of the best head porters, engine builders this sport has ever known.
