Default Ls1 Steam Vent routing - does this look right?

Bought a kit from Ebay, claims it for Ls1 and FAST 92, 102 intakes. Package had no routing diagram, neither did seller.

https://www.ebay.com/itm/31405588827...mis&media=MORE

Haven’t ​​​received my intake yet so can’t really tell. Pass rear crossover to driver side rear middle connection, so cyl 7steam goes up and pushes to top connector which goes to driver’s side front middle connector so cyl 1 pushes steam up to top connector cross over to passenger side middle connector, cyl 2 pushes up to top connector which routes to radiator.

Would appreciate any feedback if this will work or how to do a better route with these hoses.

Thanks

That sort of looks like the A-Team or Summit Racing / Trick Flow kits. I would route the lines as shown for the Summit / Trick Flow kits.

Two short lines across the front and rear of the valley cover, mid length line down the driver's side cylinder head, long line forward to the radiator.

Routing looks similar. The summit kit has a cleaner straightened look and thicker blocks but I’m not sure the hoses are long enough to route around the FAST intake, especially in the rear where MAP sensor and the vacuum hose attached.

installing heads this weekend, should have my intake by mid week, I’ll test the routing in place.

Thanks!

I ran a similar kit made by Fasster LLC when I had a FAST 92 on my car. I absolutely hated it. I could never get it to lay out exactly like the pictures or how I wanted it to look. I got it to work but it was not an enjoyable experience. A lot of swearing between getting all the fittings tight and working around the FAST intake.

I'm a very mechanically inclined person and I hated it enough that I got rid of it and sold it to someone else even disclosing my thoughts on it.

I'll see if I can find some pictures of how I ended up routing it.

Cant speak for that kit, but the Motion Raceworks kit I installed was a breeze. I have a FAST 92 on the car. Only thing the kit does not come with is the line from the top of the distribution block to the radiator.

I like the 5 port manifold block. I suppose it’s in the rear because it doesn’t look like it will clear the tight space in the front of the engine. Is it mounted to the fuel rail?

Uses two of the intake bolts.

Nice install.
I should have used the multi port manifolds.
