Dont make junk and you wont have to worry about it.
Junk? Burton, Boyer and Harvick were the class of the field up until Sunday. Harvick and Burton suffered engine failure and Boyer was right there at the front all day until he got taken out by Newman.
Yes junk. Harvicks, and Burtons engines didn't make it 350 miles counting practice. For Daytona, if you aren't going to change it, you better build it to run for 750 miles plus when you count the 150, and practice.
The ECR engines that lasted only did because they were then warned that they couldn't handle the RPM and heat levels that other engines on the track were running at and had to be babied.
