I found your forum here and find the information quite extensive. I did some reading on the 383's, and have been trying to find out which exactly mine is-b or RB?. it's a 1960 Chrysler Saratoga with the 383 golden lion in it. I've hardly got to mess with it in the 16 years I've had it and to work on it I have to drive 80 miles out of town since it's at a relatives house. To the point, I have read from many sources that there was raised blocks from 59 and 60. There seems to be allot of difference in either opinion or information. Engine is pretty filthy, where should I start?

casting numbers on block.

59 and 60 Chrysler "Golden Lion 383's" are RB, 3.75" stroke, engines.

Just measure the distance between the valve covers.(gasket lip to garket lip)
If 32cm/12.6inch it's a B.
If 34cm/13.4inch it's an RB.

I once owned one of those! A 1960 Saratoga, 2 door hard top, white, blue interior (next owner painted it red). It had a Golden Lion 383 as well, they are raised block engines, basically a 413 but not bored as much. Post a pic of yours, love to see it!

Yeah thanks guys for the help, hoping to get it moved where I live so I can start working on it again. You'll find this odd, it's white with a blue interior heh. I'll post some pics next time I take some photos.
