8620 or 5150 or 5160 camshaft blank steel? This drew a blank in the Tech Section, so I'm trying it here
------------------------------------------------------------------------------------------------------------------------------------------------
This is a technical question that will require the metallurgists around here to answer.
Crane cams suggested 8620 alloy steel for my camshaft, another vendor suggested the more common 5150 or 5160. I was told the 8620 is better, but when I look at the properties of each steel the 51xx looks better.
What is anyone's background experience with these?
Application is a GM LS2-430 CI road race engine with Jesel 1.8 solid roller lifters and rocker arms. 7/16" pushrods. Manley 221424 NexTex 1.650" Springs at 647 lbs. on All-Pro LSW-1 heads with Titanium intake and stainless exhaust valves.
The camshaft is: 256/270 .738”/.711” 113 LSA +4 advance (with 1.8 ratio rockers)
Give me your insight.
