SBM Roller Lifter Choice
Why do you think I still have those cams laying on my shelf. Lol. I promised myself that if I ever had issues one would go back in. I can’t imagine how fast I could go with them now with the heads that are available instead of the junk ported stock ones I ran.
LOL. One of the very best bracket racers I ever knew said the same thing. He refused to use a newer lobe. Ever. He always waited 5 years or so to let the springs, pushrods, rockers and such had caught up.
He almost never had any valve train issues because of that policy.
The biggest bone headed move was buying a Moroso one piece aluminum damper. That thing took out two cranks and blocks before I could get him to change it.
He actually watched me mag both cranks because I he thought I was fibbing to him because I hated that damper so much.
You could see the main webs pulled down and cracked with your eyes. It's funny, but he dropped the first engine off in the morning and I called him about 2 hours later and asked him to order a new block. He thought I was fibbing and said, no way is that engine pulled down, cleaned and magged that fast.
I said you don't need to mag it. I can see the fractures with my eyes. An hour later he came by the shop to verify.
One of those things you never forget.
