OK.. I just did a compression test. I don't know the firing order (haven't opened the book yet) but here it goes.

Front of engine to back.

Pass. side:

1) 140/150psi , 2) 140/150psi , 3) 140/150psi

Drivers side:

1) 140/150psi , 2) 0psi , 3) 140/150psi

I guess I found the problem huh??

I also took some pics.

Where does this vac. line go?

This is the hookup for the Alky system.. I have some cleaning to do.

Just a motor pic

Heres the tester I have.

------------------

Can some one direct me to a site that has the head removal instructions?

Thanks
Carl

I wish I could just pull the motor but I just don't have the room. I'm also building my mustang right next to the GN.

Soo. Not to bad for an hours work..

Also.. Can someone tell me what kind of injectors these are?

I was told they were 50# MSD's ????

Thanks

I might be wrong, but those look like 72's

they look like 50's but also 36's dont know for sure.

look like msd 50s to me. Are you gonna do both head gaskets? Its pretty straight forward removing them although a few of the back bolts can be a pain to loosen. Especially on the passenger side/

Injectors

3203's are Delphi 75's, I just checked mine. These just might be the 50's, P/N on these are 3279's from the pic.

I'm going to do both.. It's tore apart so why not.. I may even get new heads (???) I'm also going to replace some sensors & install some aftermarket gauges. I'm also thinking about picking up a CPT66 turbo from Cottons.
