And what is supposed to hook up to those nipples to provide the head to avoid the icing?
On every unmolested LT1 car I have ever seen there was a 90degree elbow on the end of the steam pipe routing it to the TB then the outlet on the driver's side of the TB is then routed back into the rest of the cooling system.
Where do you propose the TB defrost circuit gets it's heat from if not the steam pipe?

I can tell you for a FACT that the 93's did NOT have the steam pipe tee'd into the throttle body. The lower coolant hose actually has a metal section with a nipple on it for diverting through the throttle body and then into the upper hose. If you look at the radiator hose part numbers you'll find that they change in the 95 model year. Perhaps they changed it in 95 to the Tee'd in fitting, but certainly not on the 93-94's.

Maybe I am wrong but the 93 to 94 did not. The 95-97 Did have the steam pipe connected to the throttle body obviously via a rubber hose. My 95 camaro engine was directly into the steam pipe if I remember correctly. I did a buy pass before it ever even started the engine.

I dont know as far as I remember my steam pipe ran directly to the TB. The diagram and the even shboxs how to on it states the same thing. I dont know if all 95-97 were like this. Maybe SS were not? maybe oil coolers change the routing? maybe even shipping location?
by the way Shbox.com how to on how to do the TB bypass on 95-97 note step 3.

Listen I am not hear to stir up stuff just make sure the right information gets to people. I have been wrong about things plenty of times I am sure I will be wrong about something in the future. Being wrong and accepting it has become much easier with age.
ED is far passed me in knowledge and has forgotten more things then I know.

When I first came to this forum I thought ed really was one of the most knowledgable members on this forum. I never intended to start trouble, I, like you was trying to pass good info and ED made it a point to call me a liar. I have now lost all respect for him and have prayed that he sees the error in his arrogance as none of us has seen everything. I know he knows a lot, definitely way more than I when it comes to tuning. I had already planned to contact him for some tuning when I finish my project, but after this thread that wont be happening. to the OP sorry your thread went in this direction, good luck with your project, I started out just trying to help. and the info I originally posted is true and correct. sorry for deleting it. I was just trying to exit the pissing contest.

Actually on the one that I copied my system from, the supply made the 90 turn from the steam line and the return went to the T in the heater hose in the diagram above. I do not know the production date nor remember what year it was nor exactly which cooling option it had. I do know it was run as I described and I was working at a shop in san antonio tx. when I worked on that car. GM made many changes to these cars with little differences and at times mid year changes that were decided by vin breakdown, not necessarily just by model year. all the manufacturers are guilty of this, any tech that has worked in the field should realize this. 30 years as an ASE certified master auto tech, I have seen a lot of variations in many different makes and models and the only thing I will say is there is not any way that any one person could know and remember them all.

If you look closely at this pic you can see the 90 degree hose coming off the steam tube going to where the removed throttle body was, then you can see the return coming off the T and laying loose under the removed thermostatt housing. http://img120.imageshack.us/img120/4...ement01qo4.jpg

That is not my engine, that is a pic I found on the web showing the plumbing routing I had been describing. this is a pi of my 95 LT1 sitting in my 98 S10 blazer. 
It is quite a bit farther along than this now but I dont have any more recent pics

I owe everybody an apology. Evidently both of my LT1 cars had been molested with "free mods". Guess I should be happy the MAFs weren't "ported". Got to look at a low mileage one ownner virgin '96 Camaro today. Like others said: 90 degree hose off the steam tube, to the throttle body. Both of mine were 100,000 plus miles when I got them, and apprarantly had been screwed with. Sorry.

I have those valve cover and had them powder coated black. getting them on with the gaskets while inside the camaro is a pain in the rear. I have to tie string around then then cut and remove the string once installed.
looks nice though

Workin on any engine in the F body chassis is a pain in the butt. I have had several and as a tech worked on many. I have to say that other than dealing with the steering through the headers, workin on the V8 S10 isnt all that bad. after making all the necessary mods to get it in there. and there were many!
