i just recently purchased a used 383
i think its a 66
the block number is 2468130-6
the manifold number is 2206737
none of the cylinders are marked
and the firing order wasn't on the manifold i doubt it but would the firing order be the same as a 73 318?

 

Small Chrysler: Clockwise 1-8-4-3-6-5-7-2
Big Chrysler and Hemi: Counter-clockwise 1-8-4-3-6-5-7-2

 

thanks you saved me alot of time
