NEWB question about valvetrain
 

Guys,

Got a 1970 Olds 442 clone with a Rocket 350.
It's been completely rebuilt 5-6 years ago. But was sitting in storage
for the past 5 years after my Uncles nasty divorce.....just bought it off him.

My question is, I'm trying to determine if I have a solid FT or Roller or hydraulic setup.
He doesn't remember and my cousins lost all the rebuild paperwork.

I had the valve covers off and it's NOT the stock Olds setup.
It has these rockers http://www.summitracing.com/parts/CCA-1442-16/
It has these guideplates http://www.summitracing.com/parts/CCA-4842-8/
Technically my guideplates are stamped 1.6 but have the # 4862 but
I can't find those anywhere.....

I tried compressing the rocker tip arms.....and couldn't budge them.
I figured if I had hydraulic I could compress a lifter....but no go.
So I'm assuming I have a solid cam. Any way to know if it's a flat tappet or roller??

Or am I S.O.L. on this one unless I rip it apart ??

If the engine just ran, they lifter probably wont compress as it's still filled with oil.

Let it sit awhile and then try to push the push rod down. It might take a little more then your finger to push it, try putting then end of a rubber mallot on top of the pr, and lean on it a little, if it move, it's hydraulic.

Damn.....didn't even think of that. lol

I thought you could just press them down by hand no problem.
I'll try the suggestion and give it another shot.
