Hey Folks,

It would be great if someone could help identity parts of the posted valvetrain for me.

Engine is alleged to have:

Thunder Racing cam 224/224-116
Thunder Racing valve springs
Thunder Racing push rods

I have not pulled the timing gear to verify the cam as of yet.
Below are a few shots that might help, if any. I've been to the Thunder Racing site and the closest cut I could find is a 224/224-114 cam. It may be possible that this was a complete custom cut.
They don't even list any springs under their company so I have no clue about the rods and springs.










BTW, while the engine's out... recommendations to do any repairs/maintenance?
Rear main seal maybe?

 

See that paint stripe on the springs? Something tells me that those are stock springs.

 

That's what worries me too...




Check out the pic I have attached (not from the engine posted above). They're 243 heads with comp 918's. Stock ones are yellow.
