Some Dart blocks do require a taller lifter if you are using roller lifters, as the lifter bosses are taller. The SHP block is listed as having the necessary dimensions and bosses to use OEM roller lifters and camshafts.

I've used and sold both. The biggest thing is knowing how to hone them. You also often have to kiss both the lifter bores and the main bores to suit your needs.

I gotta question. Will the 31161111SHP blocks legal with a 327?While a 327 and a 350 share bore sizes and almost everything else,the 327's were all 2 bolt main.Also, do these come with bushed lifter bores? The crank I use is the large journal steel forging. I have a few of these, so that's not a problem. Just thought I'd ask.

Did NHRA change the rules about using a 4-bolt main sleeved block down to 305????

I'm running a Dart Little m block in my sbc stocker. While it's certianly beefy enough I really think it's a little on the "overkill' side for a stocker; especially an automatic car. My block weighed 217lbs bare; which is 20lbs over my filled chevy block. Just something to think about when you're scaling your car.

I'd tend to agree with Bill that the Little M is over kill for a stocker, especially when you consider cost. I would not, however, use the Dart fasteners for the main caps in either case, Little M or SHP, I'd switch to ARP studs, and align hone the block. Not sure exactly what the weight difference is between the Little M and the SHP.

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.

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!!

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?

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
