Speed Engineering longtubes lowered

Ive done a few searches, but havent quite found a shot of a lowered C10 with the speed engineering long tubes.
I'm 4/6 ECE, and my old sbc with doug thorleys were well below the frame.

My concern is pulling the trigger on the 1 3/4 LT from them. If they dont fit, its 20% restock. I'm fairly certain the shorties/mid will fit with minor alterations.

I would much rather have the LT's. Anyone 3/5 or 4/6 drop have any pics?

Thanks!

I have the 4/6 ECE drop and the long tubes. You will have no issues.

Looks like a lot of clearance.
How about your mounts? I'm running CPP adjustables with their mounts.

Sorry no pics at the moment but my 72 has the long tubes and they tuck up very high. 1971Stepside picture accurately depicts what I have.

What drop are you running? It seems like the ls headers sit higher than the old sbc headers?
Coincidence? Not sure. But if they dont hang below the frame rails I'm pulling the trigger

For the record these are the 1 3/4? Not 1 7/8 shouldn't really matter but curious
