6 years ago when i sold everything and stopped racing what motivated me to throw in the towel was the destruction of a high end engine due to lifter failure.It was a 555 with Dart 360 heads.A lifter on #3 intake valve broke and stuck open,piston hit it broke spring and droped the valve.Iam sure you know the rest of the story.The motor only had 38 passes on it and everything was new.too this day I don't know if the problem was the lifter or the lifter bore,but thats why I,am paranoid about lifters.
I am building a big inch motor now with 18* dart big chief heads no spray
single carb. I am going to spin it 7100 r.p.m. in a 2700 pound car. I would like your thoughts on this matter.
