Darts new SHP block
Dart has a new SHP block coming out set up for a one piece rear seal crank. In a 4.000 and 4.125 bore block SBC 350 mains.

Dang it! I just sold my 3.875" stroker crank for an 1-piece rear seal because I couldn't use it in anything but an LT block. I sold it too cheap also!

dart shp block
I have one of these blocks on back order. I am a worried about the 350 journals in a stroker application. I will be doing a 434, if I ever get my block.

I wouldn't run anything bigger than a 350 jurnal on any small blk. In fact i run bear spacers on the 400 blocks and have for over 25 yrs. REASON, bearing heat, in fact NASCAR runs even smaller mains, i think Hink said they were running 2" mains VS 2.450 mains that a 350 has.
Hey Warren, didn't you know you could have bought a 2 piece adaptor for the crank you sold for less than $25.00.? JMO Zip. |

OOP!!! My Bad :oops: :oops: :oops:
Not enough sleep lately, Sorry Carl. Zip. |
If you go back and read Hink's post again, he is talking about an adapter for a one piece crank in a two piece block... I am not familair with an adapter for that setup either.
I do however have the above mentioned adapter for my two piece early crank in a one piece late model block, and it works very well I really expected leaks and problems installing it, but it went in easy and so far has worked really good without a flaw... |

Zip. Here's the china version, but you'll have to make an alienment bar to drill and tap the holes, or buy one from Speedway motors. http://cgi.ebay.com/ebaymotors/REAR-...item35a52a9336 An American version. http://www.race-mart.com/items/produ...800-detail.htm Both Canton and Moroso makes them also and they are for sale at Jegs,Summit and Speedway motors, and the aleinment tool cost $22.00 on top of the adapter.

Warren, the 2 to 1 adapter is machined in two pieces, and comes apart to put the two piece seal inside of the adapter top and bottom.
Then you bolt the adapter together around the two piece crank rear journal with included allen head bolts. Then set the entire assembly into the one piece block and bolt you other main caps in. Then bolt the adapter in place just like the one piece flange cover would normally bolt in. Easy and clever way to retro cross your old crank into a new block. Jim |
