305 Small Bore SHP Block

Limited quantities are available of a 305 small bore version of Dart’s SHP block. These blocks are intended to give racers in classes that require stock displacement the option of utilizing a high performance block.

True, it adds about $800 to $1000 to the cost of a block. However, a filled 350 block with diesel sleeves would be as close to the Dart block Bub speaks of, as close as you can get without buying the Dart.

I wasn't too worried , about the extra weight as it's in the right place, prolly about the same as a 305 with hardblok or an aftermarket block.

At 28 lbs for a tall fill bucket of HardBlock, it's about equal to the weight of a sleeved block.
Just remember that you cannot use a 4 bolt block.
You may want to try using a 307 block. I have a sleeved 350 block and a sleeved 307 block and I prefer the 307.

Why can't you run a 4 bolt main block?

I'm interested in the answer to this as well.

I'm sure the Dart Block that Bub suggests is 4 bolt. I don't see the part number in the accepted parts list yet, just the 4.00" bore SHP. Does anyone have information on whether it will be added soon?

I could also drive 1.5 hours to pick up a (factory) 4 bolt main 305 block.

I wouldn't want to get either of these and have them end up being illegal.

Greg,
About 5 or 6 yrs. ago we put sleeves in a 4 bolt 350, after all the machine work was done I decided to call NHRA. They told me no way a 305 never came with anything but a 2 bolt. I would bet it would be OK now.
