How important is the oil slinger??..

How long do you want your timing chain to last? If it's a little used or drag car, no problem for awhile, but I wouldn't put 10,000 miles on it that way...
pretty much both it's going to be used probably very little and mostly drag car. And again I don't see it getting 500 Miles this winter before we get back in there and put a much hotter cam in and roller rockers and all that stuff. he had the rings gap for nitrous and has big plans for all that as well..all the stuff has been sitting in his garage for over 4 years so just getting it on the road is the main plan right now.. getting the enthusiasm built back up and then going for the gusto this next winter..
