I’m putting my 1993 3.8L Essex Supercoupe block in my 1989 Thunderbird with a Manual 5 speed transmission. I successfully got the engine out and am taking the old heads off and plan on taking it to a machine shop to get a valve job with my new heads. I also have a new aftermarket camshaft I would like to install. This is my first time installing a new camshaft and also reinstalling a crankshaft. First how do I correctly install both cam and crank without ruining anything and then second how do I tune them timing wise so I don’t blow anything?

Lift @.500 you should not have a problem with valve stem seal clearance issues.

Those videos don’t really show me how to align camshaft and get timing right.

Hello again.

I'm having a hard time finding info for you. What brand of timing chain are you going to install? I contacted Comp Cams and they mentioned on your grind cam you will just install straight up and no need to advance or retard the cam upon installation due it having 4 degrees of advance built into it. Let me know about the timing chain and we'll go from there. Hope this helps and thanks again for using 2CarPros.
