Good point, but what about the guys who flip the intake, isn't #7 still a weak cylinder? I'm guessing that it would then be a coolant flow issue.

Again, I stress the 'guessing' strategy as I'm trying to learn here, not make statements of authority or certainty.

I haven't been specifically looking so I dont remember seeing anyone flip the manifold and having problems. Not saying that they dont exist but just dont remember. We are flipping the manifold on my motor and 100% expect the egts to move in correlation with the flipped manifold. Who has flipped the manifold and had motor issues, I'd love to do more research on it.

For this reason I actually removed my rear blockoff plugs and installed my ls6 crossover tube on the rear of the heads, and cut/bent an older ls1 coolant crossover tube to make lines for the front of the heads (or just buy another ls6 crossover tube). Fit fine under the rear of the FAST intake, as I simply used T fittings and ran rubber hose to junction with the front tube before entering the radiator. I will eventually just sell the crossover tube and run Kurt's kit, as it's well designed and is a much cleaner install overall.

At the time I already had the ls6 crossover tube and picked up the ls1 tube locally for next to nothing, so for now it should help alleviate cyl 7/8 temp spikes/hot spots from trapped air. I think the coolant path is more at fault here though.

I believe Kurt posted years ago where engines were tested with the intake reversed. No 7 was still the vulnerable corner

so what does this kit go for nowadays kurt? thanks!

also, is there an advantage to running this over a factory 4 corner setup? right now my motor as it came with the car a year ago n/a had the rears with blockoffs on them and now with going fi and reading this, i'm concerned about the hot spots.

lastly, will your kit or the factory 4 post setup work with a vic jr without issue?

Well, with the factory tubes you're relying on barb/clamp style fittings to seal on each coolant tube exit and radiator fitting. Also, some prefer to eliminate the steam vent point at the radiator and tap/exit to the top of waterpump instead. Kurt's system (or any AN type fitting) would be preferrable over rubber hose/brass barb fittings, but for now it works.

A vic Jr. sits pretty high above the valley cover, so I don't see it being an issue with either.

There was a lengthy thread about this issue a while back I believe, and I thought someone was in the process of patenting/producing a reverse flow LS style waterpump.

agreed 100% with -an fittings being superior but right now the budget would be easier to cope with going to the factory 4 post setup until it's up and running. upgrades such as these that can be done later no doubt. and i have a meziere street pump so the radiator is the only point it can go to. thanks for the reply though! i will definitely get the back 1/2 of the system back to functioning again!

The KUP system is on my must do list for rebuilding my shortblock. Hopefully that and a forged bottom end will help the motor live a happy long life.

It has been years, but I did run weeks of dyno wot testing with 8 egt and 8 02 sensors with the manifold on both ways. I also had thermocouples on all 4 corners and ran the block offs in the steam locations in the rear and front depending on the direction the manifold was on. The water was the only thing that had measurable problems, and the 4 corner bleeds helped. I did change the water flow at the deck and still change some water flow that I find helpful in our engines.

will kurts vent setup work with ls6 manifold? any one have a pic of it installed?

I plan on making these whenever I get a junk block and heads to set them up on. I have the same setup on mine. It won't be cheap, but it looks baller

^^^ Nice setup!!!

Does the KUP kit work on all OEM style intakes? (LS6, FAST, etc) i.e. NOT Vic Jr style and such.

I believe the only intake it might not work with is the LS7 intake.

35thsscamaro02

so on the ls6 manifold it will work with no problem. good to know. anyone have a pic with installed?

I have a new set of these for sale for 50 dollars shipped for the set of 4 if anyone is interested. They normally sell for 64 plus shipping.

That system looks great, but it relies on velocity to work as air does not want to naturally go down. In the pictures you can see it has a factory pump, that should have enough flow to easily force the air down at rpm. If you plumbed this with the collection block higher it would make the air go into the collection block even if the engine is off. Then tap the collection block with the return line on top, that would give the air a natural escape and function best.

I have my back ports joined with AN line, T'd off to the front, and joined in a 4 way junction block then routed to the top port on the rad. Is this sufficient? The back 2 were blocked off, so this has to be better. Hopefully...
