The fact of the matter is that most trucks were available with big blocks, in a 3/4 version, so, in most cases, it will bolt right in.
There is such a thing as a 454 truck engine, also 454 passenger car engine.
yes
Yes it will. But you will need to know if the 454 requires a flywheel that is either internal or external balanced.
Yes- possible flexplate chage
Chevy actually made a C1500 with a 454 stock in the 90's, so yes.
The 454 it would have better acceleration
You can't... There's not enough steel in the cylinders to bore it that far. If you want a 454, you need to by a big block 454 Chevy engine.
Many. 348 would be a small block, whereas the 454 is a big block.
