Whats the difference between these two engines? Can someone give me as much info on these two as possible?
They are around alright. But they are not very common. Thats really all I know about them. I'm hoping someone can learn me good on this:sign6:I have never heard of a 383 RB???
i think the RB 383 is the "wide block or poly" engine... also these were the old style castings meaning they way a ton more than a new 383 or 440 block...
RB 383's WERE NOT "wide block Poly engines." RB 383's were exactly what they are termed---they were a 383 CID B type block with the same stroke and high deck as a 413, hence RB for "raised block" 383. They take the same B/RB heads as any other Mopar big block.
Also I DO wish people would stop calling the old "A" 318's also known as a "Polysphere head" as a "wide block."
The only reason the old Poly engines looked wide is the HEADS, the block IN FACT is so similar to an LA that if you had an A and an LA BLOCK sitting side by side, you'd have a little trouble telling them apart. They were, in fact, a small block design.
So the answer to the question is the rb 383 has rb deck heighth and stroke with b main size? What would the bore be? Sounds like it would be expensive to build as you,d need custom pistons.
.....and I think that you are right!I think the b/rb series went-350/361/383(B)/383(RB)/400/413/426/440
A 383RB engine is a pathetic design with the small bore size. Don't use one unless you're doing a restoration that has to be perfectly correct.Whats the difference between these two engines? Can someone give me as much info on these two as possible?
Did you know the first B was 350? Wouldn't that be fun to screw with the Shevyheads?
Did you know a 383 (B, low deck) has a shorter stroke than a Chev 350? (3.375 Mopar B, 3.48, Chev 350)
yeah it could, it could be a chevyI saw a 383RB in a wrecking yard a few years back and it had a cast iron carb. Now that would be a slug of an engine! A 383RB with a cast iron carb. Couldn't get much worse than that unless it was a /6 in a C body.
