I didn't see if this was already brought up somewhere else so I figured I'd make a post. I stopped by the Dart booth at SEMA on thursday and it would appear that Dart is making a new block to compliment their Big M. I'm holding the flyer here in my hand right now: "New! Race Series Big Block Dart. 10.600 & 11.100 deck heights. Cam raised 0.600. Dart priority main oiling. 4.840 & 4.900 bore spacing. Max bore - 4.625 w/ 4.840 spacing, 4.700 w/ 4.900 spacing. Recommended max stroke 5.500. Cubic inch capacity of 763 plus." plus some other stuff. I talked w/ one of the guys for about 15 minutes and he said that they made the first 2 castings last week and it should be available by Jan 1st. He also said that they really want to sell a lot of them and they will be trying to keep the cost down as much as possible. He said they should be about $300 more than a regular Big M. I'm really thinking hard about putting together a new motor now....
