Dart SHP Race block

SST159 · 01-16-2010, 06:21 PM

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!

Longer IC will fix that problem.

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.

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.

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

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.

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they had no idea what the length is and this should have no effect on the design of my manifold, if it did i am using outdated methods of manifold design.........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 I said "OK, get me the F'n length and i will be on my way using my outdated methods."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.....

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.
