I was planning on doing a 396, changed my mind to 383. Can the block still used? I obviously don't know much about the machining process.

Thank you

 

yes, they should have bored the block 30 over so you want have a problem using it... Its the crank that makes the diffrence... 30 over, 3.85 crank is a 396... 30 over and a 3.75 is a 383... hpoe this helps ya...

 

While the bore is OK, the oil pan rails and bottoms of the cylinder bores need to be clearanced for the specific crank/rod combination you picked. While a 383 usually requires less clearance than a 396, you need to have your specific parts checked for interference.

 

As long as its only bored 30 over its fine.

The 396 has a longer stroke.

You just need to swap cranks. Get a 3.75" stroke crank instead of a 3.875" stroke.

 

i think he is reffering to notching the block


yes, you can
they just cleared the block for a longe stroke so a shorter one will work fine

 

Thanks guys, I will post the progress once the build starts.
