Dart SHP Race block
 

Any input out there on the Dart SHP race block, Pros and Cons vs the Dart Little M.
SBC High 9 sec car 2800 lbs.

Drew just got back from Billy T house and he bought 1 and is really pleased with block, he is building a 415 ci and block looks strong.

Re: Dart SHP Race block
 

The dart website says its only good for 600 hp, and i talked to a dart tech that said they are conservative and he would trust it to 700 hp. Now, i have seen a NOS equipped run almost 1000 hp on a SHP and have no problem and you could say the same about some stock gm blocks. Shop around for the little M's and you can get awesome prices. I was able to acquire a dart little M steel billet cap block for about 600$ more than the shp. Also the SHP can't be bored as big as the little M.

Re: Dart SHP Race block
 

Thanks for the input guys.
I think I am going with the SHP.
Dart tells me it is good for at least 700 HP and has way more meat and stronger than the GM blocks. (even the older high nickel blocks)
I was leaning toward the Little M however the weight swayed me away as it is 40 -50 lbs heavier than my GM block which will mess up my chassis tune up. The SHP is only about 15 lbs more than my block.
50 lbs will put the snubbers on the frame. I doubt I will ever push more than 700 HP at it.
BTW My compliments to Dart.
The guy I spoke with spent a good hour on the phone with me and intellegently answered every important question I had.
Great job Dart!
Any other feed back, bring it on.
Thanks

Ship weight on my little m was like 205 i believe. Summit says SHP is 175 lbs. But i need all the weight i can get up front to keep the nose down!

Re: Dart SHP Race block
 

Longer IC will fix that problem.

Re: Dart SHP Race block
 

yeah but i found its not as consistent..ive got to find a happy medium. Didn't have time to play this year much. Am planning on renting a track with some others and do nothing but suspension changes all day.

Re: Dart SHP Race block
 

i dont have any personal experience with them but a roundy roundy friend of mine was looking into them and had a couple machinists say they are brittle. said the block breaks up into pieces during a problem like a thrown rod or whatever. and yes i know they all do but apparantly the machinist felt it was worse than any he had seen in a similar situation.

Re: Dart SHP Race block
 

HMMM very interesting.
How about some more input out there!

Re: Dart SHP Race block
 

Just bought one. Looks to be alot better than the money I threw away on a 400 block. Good looking casting, blind bolt holes, thick deck and cyl. walls. :)

Re: Dart SHP Race block
 

Been looking at a SHP block also. I'm curious,, are you guys filling the block or are you going to run water through it? Thanks for any info.

Re: Dart SHP Race block
 

Got the SHP block last week.
So far it looks like a nice piece for the money.
In the boreing and honing this week.
Will know more about it once I assemble for Decking.
Yes I am running water.
Keep the comments coming!

Re: Dart SHP Race block
 

Thanks Drew,,,, hope it works well for you.

Re: Dart SHP Race block
 

My stock Blk. was filled,but I was told that the Cyl. walls were thick enough that one wouldn't have to hardblock it. I'm runnig water so it should be a little lighter.;)

Re: Dart SHP Race block
 

thats great you had good customer service, I called them one time because i was doing some intake manifold design and wanted to know the intake runner length in the dart pro1 heads i have. They laughed at me (literally) and told me they had no idea what the length is and this should have no effect on the design of my manifold, if it did i am using outdated methods of manifold design......... hmmmm...... really? I said "OK, get me the F'n length and i will be on my way using my outdated methods."

I am sure most aftermarket 23 deg heads are about the same, but i did not have the number, and in todays world of 3D cad, its a couple clicks away, afterall i have spent several K$ with them.....:rolleyes:

a few days later they sent me the numbers.....


BTW, i run the little M, but i understand the SHP is a good compromise between stock and the M.
