reverse cooling? What's reverse cooling? LT1s are reverse cooled, as opposed to say L98s. What other GM vehicles, and engines have reverse cooling?

No sir, if you have a friend or someone that has taken the engine out of there car just look on the back of the LT1, look at the heads. Its not like a rubber line its like a medal line that has 2 bolts that screws into both heads. Thats how your coolint goes from one head to another. The bolts have like little pin wholes which the coolint travels.

Cool, to be honest I have never seen a LT1 engine in person. Hence why I am reading about them now!

reverse cooling is what is says. Gen1 engines the block is cooled and then the heads. GenII. If you follow the coolant flow in the water pump up to the head and down and out thru the block. The block is mostly cooled by oil not the water. One reason hardblock can be used and not really hurt anything. The steam line was required to help water get from one end of the head to the other before it turned in to local spots of steam. Mostly around the ext. valve. at low speeds.

Wow you guys managed to really screwup a pretty simple discussion.
Reverse flow cooling means the heads are cooled first a few of you got that right. The waterpump feeds each side of the engine seperately.
The "steam tube" that runs from head to head and then up to the TB in stock form(most of us bypass the TB) is there to allow air and steam pockets that might form a way to escape. Otherwise due to the whole being lighter than water thing they would get stuck at the high point in the heads and the heads would not be cooled properly. If there is not air or steam then coolant flows through that pipe. The only reason the steam tube runs from one head to the other is to join them into one line for easier plumbing, it is not a crossover.

i just took the heads off my car today because i blew a head gasket. When i took them out i bent the steam pipe behind the head and it broke in half, i was wondering if i can just connect a high pressure rubber hose with a clamp on each side. I don't want to have to go spend 100 bucks on that dam steam pipe when in reality the dam pipe is almost brand new. Something like the way the_merv has on his engine
