NEED INFO! 383bb PLEASE

The g in front of the 383 means 1971 and the e that follows could be cast crank. The 383 was discontinued in 1971 to make way for the 400 (same stroke as the 383) and I heard that some 69-71 383's 2 barrels came with a cast crank but most 383's from the early 60's to 71 were forged. The only way of knowing for sure is to look at the crank, it's easy to tell the difference between cast and forged steel which is really what you want if you intend to spin this 383 to the high RPM's it's capable of IMO anyway.
