Hydraulic roller lifter SB mystery - Help Needed

[wrogers55]

After a discussion with AFR and looking at serial numbers, here is what was shipped on the heads.

AFR-8022 (Manley Green Stripe Springs)

1.640 OD 320# @ 2.040 870#@ 1.190 Silicon Nextek

This doesn't sound good for a street motor. Man, it ran good though, for over 4,000 miles and never a whimper.

If those numbers turn out to be correct, I suppose I really need to change them for street use only???

Feel like I'm on a roller coaster with this thing. All I really wanted to do was fix a pan leak when I spotted a few little marks on one lobe!

If those are indeed the springs you have.....they are WAY too much for a hydraulic roller and is the reason you have worn lobes and worn lifters....that's overkill for most solid roller cams, much less a hydraulic roller.

You need to be about half that on the seat pressure....

You really didn't make it 4000 miles without a whimper....you wore a cam and lifters out.

OK, you win. I'll call for recommendations and you can get me another pile of parts so I can continue with all this excitement.
