B-body vs fbody lt1

[AdamG]

I am looking for a lt1 for my vette and I am actually having trouble finding a motor with accessories and wiring and pcm. I might have found a b-body motor for 500 but I have to pull it my self. I know the heads are different. But what else is different about them?

If this doesn't work out I may piece together so spare parts I have. I am just trying to avoid this because the spare block I do have was spun up to 7k and broke every rod cap in the motor. which is making me nervous about using the block.
