Do 383 B accessories, brackets, and pulleys fit RB engines?

[RockyPat]

Hello everyone, I have a 383 B engine with all these accessories: power steering pump and its brackets, alternator and its brackets, water pump, and pulleys associated with these parts and the harmonic balancer pulley.

Would these accessories and brackets fit a RB 440?

My 383 is bad, and I am wanting to get a 440 possibly.

Would I be able to use these accessories on a short block 440?

Also, I am pretty sure they fit a 400. Is that correct?

Thank you.

A 400 is also a B block so as far as I know the brackets and many other external parts would fit. As far as the 440 is concerned several brackets were were drilled for use on both the B and RB such as the alternator brackets. The power steering bolts to the water pump so you should be ok.

It may all work with nothing more than slightly longer belts

If you have A/C theres a couple parts different, otherwise your good..

Your exhaust flanges at the manifolds will be slightly higher.

Thanks for your comment. This is great news! These brackets and pulleys can get annoying to find... Lol

Thanks for the input guys. I am happy to hear that I will be able to leverage my 383 accessories on my 440.

Thanks for your comment Don. I don't know exactly what you are talking about, but I do not have manifolds for any engine. I will have to research this more.

The manifolds will bolt right on. Where the flange for the pipe bolts to the manifold will be about 3/8" higher it will pull the pipes up towards the floor. Might be okay but they will be higher

Cast and steel crank pully's are drilled different by one hole.

It's actually year based on forged balancers as well

I will take your word on that as I have never encountered it.

You can see on 440sources site and I just encountered this summer swapping a balancer on a forged 383.
