I'm with Shbox on this one. This doesn't even make sense.

For a supercharged 383, I'd make damn sure the steam tube is in.

OK, apparently I don't know anything.
That being said, I already have a crossover tube on the front (just from head to head) and I'm leaving it there. It may even prove to be beneficial for cooling.
Does anyone know the sizes of the fittings for the rear, so I can get some located and installed?

I don't see how a connection at the front has any use (especially only head to head).

The fitting size info has previously been mentioned in this thread.

Ed since I am so wrong here please explain to me why he thought "aftermarket heads allowed the crossover in front" if it were not that he didn't realize stock heads had ports front and rear?

Reread his post. Seems to me like he thinks only aftermarket heads have tapped holes on the "front".

Absolutely correct anyone with half a brain realizes they are tapped front and rear. In this case I don't see where I am talking down to him.

His next two posts were included just to make the point about how clueless he is.

He has obviously never put any coherent thought into the coolant flow and what air pockets would naturally try and do.
The overwhelming majority of us understand they will stay high as possible and coolant flow will push them rearward

Instead of the remarks and bickering that is about to happen,the OP does not know enough about Lt1s so HELP HIM OUT!

It will be to your benefit to place the steam port out back where it was designed to be.

If you choose to leave the steam ports hooked up to each other and up front you will only be shifting steam from one side to the other without dissipating into the mainstream. At that point you will have cooling problems,you will pop a headgasket,crack the heads etc. at some point.....

It's looking like I was giving him too much credit.
I probably owe you an apology.

It connects to the top of the radiator just below the filler cap. Just because the coolant temp sensor in the water pump show 180 does not mean you have no steam pockets elsewhere.

I give up.
