1. Removing ALL of the nasty casting flash from the inside and outside of the block.

2. radius all sharp edges on the block left from the machining process when the block was manufactured. That goes for aftermarket as well.

3. Clean, clean, clean, clean, clean, clean and clean. Then, clean everything 2 more times.

4. Mock up everything at lease once, sometimes twice or three times.

5. Pay very close attention to alignment of rear main seal. Customers HATE leakers.

6. No short cuts $$$$$$. You get what you pay for...

7. Do NOT be in a rush to complete assembly. You will forget something.

8. If you can't figure out why something does not fit or is not measuring out correctly, swallow your "I'm the KING Mopar Master Engine Builder and not one person on gods green earth knows more than me" pride and ask for help.

9. Have beer when job is done.
