Generation IV External Engine - l92 coolant crossover

Anyone have pics? I can get a 4 corner for a ls1... Will that work?

Answer: only if I modify my intake, you have to use one from an ls3 since the rear ports are plugged and only need the fronts. ;) damn, Google is good for something.

i opted to unplug my rear ports on my l92 heads and running the tubes on all 4 corners. rigged up a l92 & ls3 front setup pair to do everything for now, but the an fittings seem like such a cleaner setup

Any pics or a write up on the an fittings?

i havent installed mine yet, but there are a couple of different places that offer the blocks for use with AN fittings. The ones I got were not from a vendor here, so I don't think I can post a link.

Then send me a pm ;)

The norotors link just confused me more... He said to run front or rear. Then someone said all 4... I'm just going to get 2 blocks and some an fittings and run it to the top of the waterpump

They are saying that GM Engineers/race teams have found that the 2 rear vents need to be blocked. The front 2 steam vents should be run to a surge tank with a pressurized radiator cap and then back to the radiator with a free flowing radiator cap installed.

Interesting would like to see some pics of that setup.

Thanks,
Mike

Here is how mine was set up. I now have it to a bung welded in the radiator

Kurt Urban is a sponsor...his name on here is 427...and I believe he's a sponsor of both LS1Tech and Performance Trucks.

Geez the stock LS1 will work.

Looks like the old C5R race motor, but with after market parts

On my L92 I clipped the tube with hose fitting and drilled and tapped for 1/8 pipe AN-4 90 degree fitting and then ran a steel braided -4 hose to the water pump.

Lol, funny you say that. Looked one up a few weeks back and there are def some similarities.

just wondering if you happen to have more info on this?

I'm currently running 2 rear ports plugged, and just front crossover, but when I did manifold swap I was considering connecting all 4, but if what you say is valid, I will not...

I would also be interested in that

Plug them if you want 7 and 8 to run hot. There is a reason most people opt to put a little extra effort into connecting all 4 rather than blocking the rears off.

Is it safe to drill them out without pulling the heads?
