Mechanical Rooler Lifters

[Woodz428]

As I said 3-4000 miles is no durability record. By the way, I have roller cam experience going back as far as 1969 up to today.
I had a Corvair van that I drove from N.J. after I got out of the military in 1973 and put 3-4000 miles on it before the a piston popped the top and several had cracks, I guess I didn't appreciate the longetivity and durabilty that represents,LOL. Go back and read the post again,this time more slowly and possibly with a dictionary, I'm not bad-mouthing anything, just stating that solid rollers don't seem to offer long term durabilty on the street. I also stated that what works for Top Fuel and Funny cars isn't neccesarily "street" equipment, that's all. So go put another 6-7000 miles on that car like I said, then I'll let you tell me ALL about how durable they are. If you go that long without any failures, I'll re-assess my opinion. But a bunch of name calling doesn't alter the fact. I'm expressing my opinion after 35+ years in the business,just an opinion, your's as well is just an opinion. I probably don't have all your experience, but your OPINION seems to run against most I know that have replaced the parts within 5000 miles.I guess your OPINION of durabilty is different as well.
