Re: Stocker block SBC
 

Greg, according to what I've read, what I was told by NHRA, and what Dart told me (I buy direct), that SHP block IS legal for all of the small block Chevy V8 combinations. No, they do not come with bushed lifter bores, they are however CNC machined for location, so it is not necessary to bush them to correct the lifter location.

Re: Stocker block SBC
 

We CNC machine all our blocks and we also have the ability to probe the lifters bores for locations and we have not found any problmes with the ones we have checked!!

Re: Stocker block SBC
 

My main concern was with the 4 bolt mains. Most tear downs don't go that deep anymore, but I was concerned about the legality of that detail.It sounds like a great place to start. 350 010/020 blocks without core shift are getting more and more scarce. Why bother when we can get one of these!! Next question-- who is the smokin' deal for one of these?

Re: Stocker block SBC
 

4-bolt mains are legal for all applications

So I can run a Dart block, yet I'm stuck running a stamped rocker arm?

I really don't understand some of the rules for Stock

Re: Stocker block SBC
 

How much are one of these blocks??

Re: Stocker block SBC
 

Jegs shows the 4"bore, 2 pc rear main seal block, Jegs pt #301-31161111 for 1499.99 plus $ 119 truck freight. That would be a good way to get one and save $140.00 sales tax. I should get rid of all my old stuff and buy one of these.

Long time since I spoke with you. If you remember we talked eons years ago about reworking small block oil pumps. I to have CNC capability with two machines. I purchase a few Dart blocks and Bowtie blocks as well as PBM. I have 1 SHP and 2 Little M and a Big M and a Bowtie here now. But I do not purchase enough to buy direct at a great cost, so I purchase from a good vendor that handily takes care of me( they sort thru a larger inventory than I could ever keep to help me). Have you had the opportunity to check the SHP after several runs (circle tracks) and saw any problems with their integrity as compared with the Little M.. Have you noticed the inability to keep seal after severe use and walking around of the mains.

Go to the head of the line! :)

Re: Stocker block SBC
 

So far we have seen no issues as we have 2 guys one with a twin turbo build that is making appox. 850 horse and another procharger build that is appox. 825 horse and both are 3 years old and still running great.

On most of the blocks we machine we do add main studs and when using head studs we use a .950 stud bottom tap the head bolt holes and drop a ball bearing in the holes and screw the studs in as it keeps the cylinder much rounder on the bigger bore blocks, Rather bottoming a .750 stud out on the top of the deck.

Most leak downs are right at 2%

Using a good hone and the correct stones are key to having good ring seal and long life.

Hope this helps
