Guys with ece mounts?

[fast&low]

Lol They will with a little fab work & they give you front and rear adjustability
I mean in the early 90s that's what they used to say about LS swaps into classics.
OK being serious now I was commenting on another post and somehow got mixed up with this post but look up Ironworks Speed & Kustoms they make a nice mounting bracket it's amazing I haven't seen them more on these trucks it's a real nice set up the one that you want is the LS1 bracket fits like a glove & you can mount it just about anywhere I mounted mine on the driversside between brake booster & hood hinge looks almost like the factory put it there.
I hope this helps
