Tradition?
Don't know.
Are they related to Nascar blocks in any way?
Don't know diddley about Nascar
Do they start life as a stock block from a manufacturer?
They can, but the Dart block is more cost effective & is of more consistant quality.
Why don't they use a sprint car aluminum 410 in SC?
Speeds are about as fast as SC cars can "safely" crash with the 355's
If they did, could you swap the engines between a sprint car and an SC car?
Probably, but I think I would want to change the camshaft because of the track length & the car weight.
