421 or 427 sbc rotating assembly in a 400 gm passenger block
will it work and wat style main caps will work
|
With both the 3.875" and 4.00" stroke cranks you'll need to clearance the block. Additionally, you'll need a .900" small base-circle cam and have to check the clearance with the rods and cam lobes.
Both cranks are built to work with the 400 main bearing diameters. Also, the GM 400 blocks will not hold-up as-well-as Dart 400 blocks. WD |

They sound like hardcore guys

That isnt being hardcore, thats just showing there ignorance to a obvious problem! I have seen three here in my circle of friends split in bracket motors. No power adders at all, single carb bracket engines. They split about a inch down from the top of the cylinder. I think they would be fine in a street engine but .060 over is a no-no in any combo.

Agree, stubborn ignorance & wanting to stay that way obviously. |
Actually it was only a page or two not 4 ...here is the quote that upset two or three people.One of them called it "rude"

The 400 sb chevy block is a hunk of junk. I have seen several bust . If you were going to spend money on a 400 an aftermarket block should be on top of the list even before good cylinder heads. They are just not very reliable at high power levels...still a great street motor though.

See I really dont see anything wrong with what you said. You said everything based on facts not opinion. So they should have respected that and possibly let it go or just reply to it with their facts. JMO
