Someone needs to start re-casting 340 blocks
I had a really nice 340 block for sale a few years back coupled with a set of new in the box W2 heads. Actually took me a while to sell that stuff and I wasn't asking super high prices.
As many of you know I design, make and sell parts for big blocks and small blocks. Big block stuff outsells small block stuff by a wide margin. At least 3 to 1 and maybe 4 to 1 ratio. I've given up on designing new parts for the SB since the volume is so low. It just isn't worth it for me to invest money into making SB parts because there aren't enough buyers to justify the investment. I've done a production run of SB parts before and had to wait several years to get my money back. When that happens I delete the part number and focus my energy elsewhere.
