What do you think of the new info on block webs, etc. on the following site?
http://www.440source.com/blockinfo.htm
I was happy to see it. Nice pictures, good info.
FWIW, the '75 400 block in my current motor has the wide block webs shown on that sites '73 motor. Mine has the 3.75" wide connection to the bore, and the 0.57" thick area.
Since the 440 blocks were only about .375" thick the 400 block could be align bored for 440 mains and still be better than a 440 block. .575-0.375=0.200" thicker, bored to 440 mains it would still be 0.140" thicker than a 440 block.

That is another good point Jim. By not grinding on the high dollar crank, I can probably use it for many years in different motors.
Chenoweth Racing Enterprises did the machine work on my block. Talk to them if you want some idea on the amount of work that it takes to bore a 400 block to 440 mains. It is a huge amount of work but sometimes you have to do what you have to do.
Someone needs to build a low deck race block. Anyone have a spare $200,000 sitting around in a money market account that you want to invest in some patterns? A high quality low deck race block with 2.75 mains, cross bolted, bushed lifter bores, priority oiling system, ready for roller bearing cams, etc. Wow, those things would sell.
