Road Runner Nest

What were the main changes done to the 383 in 1971 compared to earlier models in the Roadrunner line-up since 1968?

My roadrunner has one of the last 383's ever produced. I have a 440 and spare 383, and am holding myself back from putting in a 440 or 383 stroker.

How were these engines as overall performers (Pros and Cons)? I want to keep the motor's "stock appearance" ie hi-po manifolds etc. May be able to make an aluminum manifold appear stock.

Did 1971 383's come with forged bottom ends (crank, rods, pistons)?

1970 was the last year for the forged cranks. There where the leftovers that got put in the early 71 cars. I think most of the big block rods are the same except for the 6pac motors.
