Has anyone considered these gm blocks for a build up?
or is this something that would end up costing too much?
or what about the 2nd one on the page

To keep things going in this thread. I've been wondering how many dry sump syty's there are out there? And have they used aftermarket blocks, or the stock ones?

Second question would be; Whats better in the long run. The block above, or a bowtie? They are both around the same price, are they not?

And have fun with the second block and that two piece rear main seal.
