B is 1966, casting date on side of block as well.

Looks like a 1966 assembly date with an undersize crank or over size bore. I don't remember for sure which the maltese cross was for

Ok Thanks All .Now ummm I’m wanting to rebuild, having finding this out should I not bother , what is the main difference between this engine and r/r engine . Maybe try an source a 440 block and start from scratch, your view?

Only minor differences between a regular 383 and a rr 383 HP, mainly just slightly hotter cam. I have my matching numbers engine and it will look stock but I built it up a bit for more torque and HP but nothing crazy as it`s going to be a nice cruiser. I would just build up your `66 383 how you want and unless they climb under it no one will ever know it`s not the factory engine.

5 Horse power difference is pretty easy to make up. The main difference is the 440 cam was used in the HP383. I would be more interested in what heads are on your 383.

I’m not really fussed about the having the numbers on the side block ;more interested in what’s inside.You mentioned’what type of heads.How can I check? Under the valve covers?

 

[69hemibeep]

Yes under the valve covers

My 69 came with an early 383 block, but they told me it was not a numbers matching HP but it had all the HP parts. It did. It ran well, but it leaked and burned a little oil. I rebuilt it with the 906 heads, KB flattops, a bigger cam, RPM Performer intake, 650 Holley, and headers. It runs and looks great. I would rebuild yours. Unless you want to take it to the track a 383 is fine. Your call.

It's an aluminum 22-inch from US Radiator. Part Number: AL035219SNDZ-9. Works fine.
