Last August I installed a Crower 00320 cam advanced 4deg,with cool face lifters,hardened pushrods and ss roller rockers.[IMG][/IMG]
COOLFACE SOLID LIFTERS
Engine builders know that cam lobe and lifter
wear is caused by inadequate oil lubrication
at the cam and lifter surface.
With today’s high rpm, high rocker ratio
and high spring pressures, cam and lifter
failure is at an all time high. Crower’s all new
“CoolFace” lifter option is a must for these
applications. Features a small diameter
oil metering port (.024") that is precision
machined in the face of the lifter. No
significant oil pressure loss, but significantly
improved cam and lifter longevity.
Happy to report all is well and I'm very pleased with this combo.Lash settings have not changed since the initial break in.Motor is quick revving and very responsive.I was looking into a retro-roller setup but seemed to me to much hassle with cam play,correct cam gear and the link bar lifters failing.The cost was also a factor.Figured those cool face lifters would put more oil on the cam lobes to help avoid a flat lobe.I'm using VR1 oil which states it has ZDDP added right on the label.So far so good close to 1k miles on the new cam.....The Valvoline VR-1 Racing Motor Oil
• The #1 selling Racing Oil of all time and race track proven.
• Protects against high-temperature deposits for a cleaner engine.
• ZDDP additive provides tough anti-wear protection.
• Enhanced with friction modifier to improve horsepower.
• Formulated with enhanced anti-foam system.

 

At first I was thinking 1000 miles since last year?????? Because I put on more than that in one day. Then i see Hawaii. I lived in Oahu for 6 years and it was a long drive to the north shore

What really saves solids is the newer breads of small lash cams. I run my SR at .010/.012

 

Hey I can only drive in a circle here on this island! One big circle. Vette is my weekend cruzer so not much miles driven.Moved from Oahu to Kona back in 81.North shore is still country not much changes on that side of the island.Honolulu is just plain crazy these days traffic everywhere all the time.
Who has those close lash cams?..Aloha's

 

I have the same Crower lifters im my L88 engine ( comp cam ZL1 tight lash cam ) and everything OK till now ( just 800 miles btw )
VR1 is well known to be not ok . check the forum. go for Amsoil Zrod oil

 

I really like the Zrod stuff but dont see the issue with VR1?
The film strength is something else!!
Takes forever to wash it off your hands moreseo than any synthetic Ive used.
Good news on the cool face lifters.
HAve a 400 in the garage that, if I have too many issues with the .026 lash solid roller in my stroker Ill just build a basic 406 with a flat tappet.

 

Using VR1 because NAPA has it here in Hawaii.Can't get special oil shipped to Hawaii anymore with out huge shipping fees.It's really criminal how the costs have gone up.The VR1 states on the bottle it has ZDDP added to it.Any one else had a problem with VR1? Thanks for the heads up......Aloha's

 

Concerns with VR1 center around inconsistent oil analysis results...although it's hard to determine how much weight to give to that.

That said, racing oils aren't the best choice for street use as the additive package is not designed for extended change intervals or start-and-stop cycles. But if that's what you can get, then it's far better than a no-name oil and a no-name additive.

Let's not turn this into an oil thread

Thanks Much! Will check it out.......

 

I looked up your cam specs. How does it run? at what rpm does it seem to nose over?

I use VR1 10W-30

 

I've been using those exact lifters for many years in my avatar car and 69 Vette. The valve lash hasn't changed in the last 2-3 years. I also use this oil in the 69 since it has the high zinc additive package.

I'm using up surplus Mobil 1 for the Z28 but I add ZDDP to it.
