hey guys i have decided on going roller,ok i know sadi rollers are cast does this mean you can use a stock oil pump shaft with steel gear????next question can you get a true 8620 billet roller cam with a cast gear??i want to avoid running a bronze gear altogether cause its going to be a street car..

sadi is a cast not billet roller,the price differnce is like 25 bucks,if you dont specify this when you order a cam they will send you a sadi cast cam and not the 8620 billet....

Must be some fly-by-night cam company. I'd go out on a limb by saying that all performance solid roller cams are billet. Hydraulic roller cams "might" be cast depending on the manufacturer but they sure as hell wouldn't surprise you with it!

CompCams,they sell plenty of solid roller grinds on cast cores. Mopars are a little harder to come by cast cores at least for BB mopars. SB's come with a cast core that's often reground,but your very limited to what you can do with that.
not saying it hasn't happened but I have never gotten a cast solid roller from comp or anyone else but I don't doubt that they are out there.

My point was that no reputable cam company would surprise you with a cast roller ... you'd know what you were getting either from the catalog or when you ordered it. Anyhow, to the OP's question ... Quote:

YES
Quote:

There seem to be a few folks on here who think you can. However, I've yet to figure out how anyone could press on a gear that is smaller than the front cam journal !!! Explain that and I'll be a believer!

I guess that Comp is no longer reputable,in your words.
Nothing wrong with Comp ... -8 is cast, -9 is billet ... no surprises !!

It's not suprising that your wrong,again. Order a PN 20-813-9 sounds like a billet core! That -9 means it is,that's what you are telling us. Wrong.It's a cast core. Again. Wow! What a suprise.

so guys are you sayin that if i do get an sadi cam ....a stock type steel gear will work....cause i dont want to replace a bronze gear at every oil change....i am not opposed on sadi they are used all the time with success but when your spring rates are crazy and you rev the engine high with a solid roller type lifters then a billet cam is a must...also there are alot of cams that look billet or have copper look to them or they machine down the casting in between the lobes that look billet but are not...the way you can tell if there is cnc marks in between the lobes..i think...

Hmmm ... I'm looking at the Comp catalog and not only does it say -9's are solid billet but that particular core number falls under their heading of "RACE ROLLER CAM CORES - STEEL BILLET".
Maybe you just got screwed when you bought yours at the swapmeet ... I'd have it checked if I were you, it's probably just a stock hydraulic cam that someone scratched that # into!
