Should a 71 383 have a stamped pad like this one?

No that's a 440, 426 thing. Not on a 383. It's the quickest way to tell the difference between a 383 and 440 :bigthumb:

383 is a "B" engine. Look on the right side of the block near the base of the distributor for the identification pad
Keep yer foot in it

Now I'm really confused. I thought it was a B engine and had the pad?

Now I'm really confused. I thought B engine had a pad based on the above reference material?

383 & 400 are "B" engines

440 & 426 are "RB" engines

I see on your reference material that 383 is listed twice, which I assumed is incorrect. :dunno: I've never heard of a 383 RB block :huh:

Not the case here, but there was a 383 RB introduced in 1959
The first 383 was introduced in 1959, but as the raised block. The dimensions on this engine were a bore of 4.030 and a stroke of 3.750 inches. This engine was available with two four-barrel induction and a horsepower rating of 345 @ 5000 rpm.

The first year Chrysler made the 383 it was an RB, I think it was 1958. Other than that they are B-engines with no raised pad.

I was wrong on the year of the RB 383. It apparently was 59-60. According to Wiki anyway.

Not to be confused with the 383 B engine, the 383 RB had a 4 1⁄32-inch (102.4 mm) bore (with the long stroke of 3 3⁄4-inch (95.3 mm)) for a displacement of 383 cu in (6.3 L). It was only available in 1959 and 1960 on the US-built Chrysler Windsors and Saratogas; one of Trenton Engine's lines had been converted to the new RB engine (to make the 413), and demand for the 383 B engine was too high for the remaining line. The solution was to create a 383 RB to fill the gap until the plant figured out how to quickly switch from one block to the other.

So I still wonder if this old 383 RB block had a "pad" like the 440 ? :thinking:
