Aftermarket Cast Iron SBC Cylinder Blocks
 

Is anyone aware of an available aftermarket/performance cast iron cylinder block that is machined for a small-journal crankshaft? I'm looking for options for next year.

Thanks!

Not that I am aware of. Dart might be interested in making a run of them, but I wouldn't hold my breath.

I'd say your only hope is to go on a quest for a small journal Bow-Tie block, good luck with that. Have not seen one in a long time.

Thank you all for sharing your knowledge. I myself had never seen one, but I've been told to "never say never"! I was just hoping that I wouldn't have to repeat my "buy three and get two boat anchor's" fiasco of two years ago. :o

Now I have some shopping to do!

Race Engineering offers main bearing spacers that allow the use of conventional small journal bearings in a medium journal block.

I used a set of these in a 350 block with a 283 crank and they worked fine. Be sure to check the tang notches though, the one for the rear main was slightly off location on my set which required a little hand-fitting to avoid binding the bearing, no big deal but it does need to be checked.

Dart will cast you anything you want in a block within reason. ANYTHING! But, be prepared to spend some $'s.
