Initial problems and issues I hope to resolve with this rebuild:

• 383 stroker engine uses too much oil.
• Small oil leak that no one could find.
• Engine vibration beginning at 3000 RPM and worsening to 6000 RPM.
• Endless issues with the Borla headers and Y-pipe.
• Left O2 sensor requires a harness extender.
• Sparkplug wires currently require routing over the valve covers to avoid being burned on the headers.
• Only the right motor mount is Poly... I couldn't change the left one.

What I changed:

• Switch from Borla to MAC headers(Jet-Hot coated).
• Switch from Total Seal Gapless® second rings to Gapless® top rings
• Switch from standard header flange bolts to Stage-8 bolts
• Went back to routing the sparkplug wires in the stock(factory) location

Final results:

• After 1500 miles, engine STILL uses oil !!!!!
• Oil leak stopped! I believe this was comming from the water pump drive seal.
• Engine vibration stopped.
• No more leaking exhaust flanges. Thanks to Mac Headers.

Some things never change...

• Don't trust that the parts/services you recieve will be correct for your application.  If they ARE correct, they may not work as you had hoped!
• Measure EVERYTHING-- TWICE!!!!!
• Nothing is sacred...  EVERYONE is capable of errors, oversights, omissions and/or conflicting opinions.
