Hi,

I'm totally new to the engine modification so pardon my newbie questions

So the L69 of my T/A has an Edelbrock 7102 camshaft with the hydraulic lifters that came with it, but I want to put back the original camshaft in.

Do I have to replace the bearings ?
Do I need new lifters ?

Thanks, Bye

 

Why would you put the original cam back in?

So long as you're careful while removing the cam as to not knick the bearings, they can be reused.

Yes, you'll need new lifters.

 

Ok, thanks for the help

I'm putting the car back to original, I bought her with this camshaft in.

 

you're better off leaving the cam you have in there. If you want to swap to an original cam you'll need a new cam and lifter set to be safe, plus all of the gaskets.
