Coolant crossover conversion questions.
I'm still new to the LSx stuff and am doing a retro fit into an older vehicle. My question revolves the coolant crossovers. I am gonna convert mine over to braided fuel hose and fittings and am curious weither I should just block off the rear or connect all 4 together? Would there be any difference in cooling system demand levels to decide which to do (i.e. horsepower level)?
Thanks!
Thanks!

the back being plugged off is beleived by some to help make no7 go.. i have a fast and even though it was a pita to make; all mine are connected. went over the intake instead of under. made my own blocks out of brass and ss tube to connect to rubber line and a few t fittings.

So your saying that some think that blocking the rear steam crossover contribute to the problems with the #7 cylinder? Thanks.

If the rears are capped off, and the front is still joined together you should not have an issue. this is the way that all ls6's came from the factory, as well as 01-02 f-bodies equiped with a ls6 manifold. If you see a number of number 7 going out, look at the situations. No2, fI, high mileage, beat to ****, or generally worked on by someone who should not work on a car, or other factors. Now do not get me wrong here, things happen, but if proper coolant manitaince is done and motor is maintaned, things usually just do not happen out of the blue. Cap them of and put your time and money elsewhere, IMO

Thank you. I was just speculating ideas from the Gen1 stuff like tying the coolant passages together front to rear, etc. Didnt know if any of that had any merit on these engines or even mattered or if it would hurt anything. I'm sure this is the least of my worries on my build but I like the little trick things to stand out and function and have reason. I dont see the steam crossovers doing much to # 7 myself either unless the engine is tuned to the edge and that being the hottest cylinder it ges first.Thanks.
