I have been reading up on the 400 SHP assembled Dart short block. It sure seems like a stout unit for $3300.00. Are there any of you out there who has bought and ran one? My thinking was to use a roller Hyd cam, GM fast burn heads and a Edelbrock air gap intake. Any feedback will be appreciated.
Has anyone used the DART 400 SHP Short Block?

I agree that is a lot of money for a short block since you should be able to get a GM Turnkey 383 for about 6000 or so there is a guy or ebay right now, Roby performance that has the 383 for 5,595. I have seen the SHP at a local speed shop and it is a nice piece but that 383 looks like a deal to me.

Actually those deals are very good for what you are getting. That block is nice and if you are talking about the same shortblock I have seen than it comes with forged eagle crank, h-beam rods and forged pistons. A very good base to build a nice motor. You would be hard pressed to build the same thing with the same quality parts for less. Good heads, roller cam and the air gap and you have a killer streetable motor. Not sure I would go with the fast burns though.
On edit those fast burn heads do look nice for the price. I might also run a single plane. That is a large enough motor that a single plane of the right proportions could work just fine. Nothing wrong with the airgap though.

The SHP block is a nice peice compare to the old GM 400 and 350 blocks as we have probably machined and sold appox 60 of them since they Dart came out with them and to date no problems.
Here is a guy we machined an SHP block and sold a rotator al clearanced out ready to assemble this guy has a 2.73 rear gear and twin turboed as well.

If you have experience machining them, do you recommend going through the whole block (line honing, decking, etc) or can you get by with just a bore and hone if you are going to keep the deck at the same height?

We have sold appox. 60 of them and machined everyone one so far and on the main lines most guys want a stud kit added for security reasons or they are going to make some serious HP and when going to studs or even breaking the caps down and relube and retorque they some times will change demension, With that being said all the Dart SHP blocks that leave our shop the main line is at 2.6415
Decking, There are not to many pistons made for zero deck at 9.025 deck height. Most guys shoot for zero deck with most of the blocks we machine. So we do cut all the decks to their specs.
We do make sure the lifter bores are at .844 and some customers go to .875 or .904 lifter bores so we do what they ask.
Even cam tunnels they see to be right on spec and some guys have us blue print bore them to BBC for their application.
Bores, Some guys what a 4.030 or a 4.155 bore ETC. and we bore as needed and plate hone to what they are using for hardware and gaskets that will be used in the end build.
All the pipe plug holes have to be taped deeper because Dart uses straight pipe taps when machining their blocks.
All our work is done in a HAAS 4-axis CNC machining center and those blocks run all machined 1795.00 and shipping is 75.00 any wheres in the U.S.
We are able to probe the blocks out for cylinder locations, deck heights, lifter bore locations ETC. and from what I have seen Compared to do the OEM blocks the DART blocks are light years ahead those older blocks
Here is a little bit of what we do.

SHP blocks
before you spend all this money on machine work, why dont you just order a good iron eagle block machined to your standards from dart. it is one **** of a lot cheaper, and you get a better block. there is no reason to buy a block and have some good ole boy put it on his cnc machine when the block maker can do it for much less!

W-T-F a Dart Iron Eagle block this is built for a dry sump only but can be converted to wet sump, Plus why would you want to run a raised cam tunnel block and it also has a spread pan rail, it also has no oil returns in the lifter galley and would have to machine in oil returns. The Iron eagle has no place for an oil filter and has to run a remote oil filter.
Lets see a Dart Iron Eagle block jobber price with no machine work is 2791.39 and an SHP block jobber price with no machine work done is 1455.97 please enlighten me on where the big savings is:sign0020::sign0020:
Now lets see we have been selling the SHP block all machined, Line hone to 2.6415, deck to the customer spec and bored if needed and plate honed to the cusotmers specs, lifter bores clearanced cleaned ready to assemble for 1795.00 and we ship any where in the U.S. for 75.00.
So know we have 1870.00 in a block all machined ready to go and shipped the Iron Eagle block is 2791.39 with no machine work done.Again please enlighten me on the savings here:congrats:
Now have you ever bought a pan for a spead pan rail block or bought timing set for one of these blocks???? again please enlighten me on where the big savings is here
And also since there is no place for a oil filter on the block now you have to buy a remote oil filter and the plubming as well. Again please enlighten me on the savings here
WOW you are really a bundle of imformation:congrats::congrats:

CNC Blocks, don't get too upset with the above / previous post, You can tell he doesn't know S**T about what he spews. He's just another keyboard engine builder
It sounds to me that you folks do a very thorough job, and at a fair price.

Nobody has been had here only by you posting a Dart Iron Eagle block is cheaper then the SHP block is total BS thats for sure.
You have a queer sence of humor thats for sure and you should take your life style some where else
I post on abut 20 other boards giving out factual info and I don't mislead people like you do.

Maybe a monkey could run a CNC machine but I can tell you sure couldn't :wavey::happy0030: Look at the bad info you gave about the Iron Eagle block being so cheap.
I sure can tell by the emails and phone calls you have generated what others think of you
arty0031:What sale is Dart having this week on their blocks???
