As indicated in the 440 source writeup and a MA article written about the same time, the later blocks are in many respects better for a hi po build. In practice they do fine up to the limits of any stock block. The most important thing seems to be to check cylinder wall thickness if you are making lots of power and/or pushing the overbore. That varies quite a bit from block to block and hole to hole.

That varies quite a bit from block to block and hole to hole. I think the MA article concluded that the later blocks were thicker and heavier that the earlier ones, but the cast iron used was a tad bit softer. Since we're talking about high nickel blocks, were the 426 Hemi's high nickel content? What about the industrial blocks (413, 426 etc)?

Wouldn't be difficult to send em 2 different minute chunks from 2 different blocks to be analyzed. No idea on the cost or even the company name but it could be found if a person wanted to get serious about this live every 24 hour block of time like it's your last day on earth

The old DC performance book refers to the 'X' block as being a 'hi-tin content' block. Can't find anything on high nickel. "We live in a time when intelligent people are being silenced so that stupid people won't be offended".

The 426 wege NASCAR blocks where suppose to be high nickle content and I heard, not from a Mopar employee, that some of the Chrysler marine blocks, all sizes, not just B & RB blocks where high nickel also BTW, as far as the X designation on castings from Mopar I was told by Larry Shepard or Tom Hoover(at one of the drag seminars back in the late 1970s) that the X desgination indicated heat treat on those castings Mr.Cab Racing and winning with Mopars since 1964.

There is ZERO reason not to use a later block and in many cases it's a better choice due to improvements in the castings and less core shift.......Check the block and use it if it's good; the year is irrelevant.

There should be an Urban Myth section in the Archives where we could put some of this stuff and then we could just link it instead of typing...... Let's see, we could start out with the following; - HP2/6 Pack Blocks - "6 Pack" rods - 906 "440 Magnum Heads" - thick/thinwall castings - one of my personal favorites; '70 Coronet grills came from the Edsel! - All 6 pack cars got torque boxes - All 6 pack cars got 26" rads - a 383 is significantly lighter than a 440 .....there has to be dozens more, though some would be a little "controversial" And of course, we need the sign; Dave 1970 Super Bee 440 Six Pack 1974 'Cuda 2008 Ram 3500 Diesel 2006 Ram 3500 Diesel 2004.5 Ram 2500 Diesel 2003 Ram 3500 Diesel 2006 Durango Limited [url] http://1970superbee.piczo.com [/url]

No idea on the cost or even the company name but it could be found if a person wanted to get serious about this IIRC, that's what MA did and their conclusion was "While the blocks cast after 1976 do not appear to be "thin wall" castings, they do appear to be cast from a material which is inferior to the earlier castings. It could have been this knowledge that led the MP engineers to caution racers against using the later blocks." The INTERNET, the MISinformation superhighway
