Help Me Please! Auto To 4-speed Help Needed

I have a 71 ventura that has a 4-speed in it.
Im wanting to put my small block chevy down into it but I noticed something on the engine I removed from the car. It has a place on the rear drivers side of the block for the Z-bar to hook up to and I noticed on my small block that it doesnt appear to have that same design to hook the z-bar up to. Am I missing something here. Do you have to use a engine that came from the factory with a 4-speed?
Someone please help me out here.
Thanks

Hmmm? Dont know why my pictures wont show up, the way everything went while posting them just fine but no pics.
Well email me and I will email you back the pics showing what Im talking about.

cant believe know one knows what Im talking about here.
Anyone??

If this car had a Pontiac 400 engine, who knows? Those cars never came with a Pontiac engine until the '74 GTO version, and even then, it was a 350. Now when you're trying to put a SBC back in, who's to say? The biggest engine that car came with was a 307 SBC. That car has had 34 years to be cobbled. Who's to say it needs the Z-bar? My guess is that car came with a six cylinder and an automatic to start with.

Yes I know all that. And yes it was a 400 that I removed from it. And I know it wasnt factory too.
And its not cobbled up either, everything was installed like factory from a nova.
All I need to know is do I have to have a smallblock that was made from the factory for a 4-speed or can I use a motor that was orignally mated to a automatic?

To answer your question to the best of my understanding..NO you do not have to mate factory standards to standard transmissions...They interchange except that the back of an automatic engine won't have a pressure plate or a clutch, it will have a flywheel.

The motor will accept man. or auto. You just have to put the right stuff on it.

The reason I asked is because I dont see a place on the side of my block to attatch the Z-bar on my smallblock like there is on my 400 pontiac engine.
So thus not seeing this on my smallblock chevy makes me think the block was made for auto tranny only.

On a SBC, there is a 3/8" threaded hole above the oil filter that a pivto ball on a stud screws in to. The Z-Bar pivots on it.
