La B/rb?

[freshayr]

I am looking at the year one catalog for an oil
tube and dipstick. What do they mean when they refer to a year and then say LA or B/RB?

 

[lgjhn]

They're referring to the engine series....
LA is the later model small blocks; 273, 318 340, 360 etc...
B is the big block 361, 383, 400 etc.
and RB (raised block) is the 440

I think the 413 and the 426 wedge also fall into the RB catigory

so what would a 69 340 be?

Small block before 93 are LAs

Small blocks after 93 are magnums

B motors are 350, 361, 383 and 400

RBs are 413, 426 and 440s

There were also two variations of the 318...the "A" Poly used between '57 and '67 and then the "LA" showed up in '67.

Here's a comprehensive list of Ma Mopar's engines...

True dat...I often overlook the 273 because of it's lack of popularity!! LOL!!
