Under $4k budget build LA360 build

in the past I've used a book called "how to rebuild your small block Mopar engine"
this one is pricey but there are others available. https://www.amazon.com/dp/0895861283/?tag=fabo03-20

This book will tell you the parts interchangeability etc. As well as it will tell you how to actually assemble the engine.
Yep. That's the book where I got this info about the cranks from. Highly recommended.
