It was likely a 400 Dart block.
I have never seen a Dart 350 block. Do they exist?
Can you even call it that? It’s a hybrid...you can get a 4.000 or 4.125 bore and it can accommodate so thing like a 4.100 stroke. Uses LS bearings etc...I don’t think they consider it a 350 or 400 block.
Don't know. It's not really a 5.3, 6.0 or 6.2 either. Unless you have quality genI stuff laying around, I do not know why you would build this particular motor. I think most would build one or the other. The modern top end seems to be the biggest, maybe only, reason.
It says 350 mains in the description. I thought that indicated genI crank/bearings.
I don’t see a compelling reason to have this hybrid either unless you purposely want a big cube SBC but want LS heads. But you can always get killer heads for a SBC too...
I rather buy a aftermarket LS block.
Dart has both SHP and Little M blocks with 350 mains
My Shafiroff 427sbc has a Dart block with 4.125 bore with 4.0000 stroke using 6" rods
If you already have SBC running gear all sorted out you may not want to swap all of that stuff back out to run an LS. That's where I am presently, I have the transmission, bellhousing, driveshaft and turbo exhaust all of that stuff worked out and really do not care to reinvent everything again to get an LS in there.
I would feel the same if I ever go turbo.
