NEW???? Dart sbc block
Are these new? has anybody used them or have any information about them? Would they be good for the typical 500-700 hp street/strip/bracket type build?
From what i can find they are about 30 lbs lighter than a Little m sportsman block. That's nice weight reduction off the front end. They have .230"min@4.165" wall thickness compared to the Little M's .275"min@4.185" and the deck is also thinner at .625" compared to .675".

About $500 cheaper than the little m sportsman.
Who is Dart aiming this at?

"New" Dart SB's
Here's a copy of a post I made on the Chevelle forums a few weeks back:
(Quote) The blocks' bores will be 4.000" and 4.125" (both undersized from Dart), they will use (5) 2.000" cam bearings, have "blind" head bolt holes, .625" thick decks, and be recommended for "Special High Performance" applications.
They will have main caps 1-5 will have 7/16" fasteners with the outer fasteners on the center 3 being 3/8" splayed.
Wet or dry sump options and "priority-main" oiling.
Most all of the SB components will be able to be maintained, oil pump, pan, oil pump drive, timing cover, etc.
Shipping weight approx 175#.
Thanks, Gary in N.Y.
P.S. The part numbers from Dart are DT311-611-11 (4.000") and DT311-612-11 (4.125") and not sure when they will be available. Price should be in the $1450.00 range or thereabouts! (End quote)
I can add they will most likely handle the 600/700 HP numbers with no issues.
As stated above the "recommended" overbore will be 4.165" and it is also recommended to keep the stroke at 3.750". This will all "prove-out" in the real world as they are used!
It will have a provision for a "mechanical" fuel pump! Lifter bores will be sent out at .843"/.844", hopefully!!
The early SB/2 pc. rear-main-seal castings from G.M. are becoming somewhat "scarce" and may be the reason Dart chose this platform!

That is it sanfordandson. Its a kick ass alternative than any oem block. These are not made in china. There made in Detroit michigan just like the rest of there blocks and heads. Made in the USA like Edelbrokes stuff. Now what the hell is wrong with the rest if the industry if these guys can do it. Oh just wait and see what else is coming.
