12 different posters on here and everyone can't even agree if they should be cast at all let alone what configuration! Surprised nobody has complained about the cost even though there hasn't been any form of pricing what so ever for said suggested blocks... Book engines start at $89,000 and go up from there, who on here is gonna shell out even half of that for one??? Book builds record setting engines in super stock, comp eliminator, and Ausie pro stock. Most of those guys have pretty much unlimited budgets, maybe not the super stock guys, but look at the upper end of super stock. $150,000+ AH Hemis and COPO Camaros, cobra Jets, and Hellcats. Record setting Comp eliminator cars are double that. Most on here would want a tall deck block which is not what Book wants as short deck motors make more power as he has proven time and time again. He would like to have blocks cast so he can continue building, developing, and selling these engines but there needs to be enough serious interest and commitment to buy to make it worthwhile to cast the blocks. I have no idea how many would need to be cast to make it worthwhile for whomever has it done, but it would be safe to say more than 12. Sure you could have a one off cast block made at a lot of foundries around the country, but the cost would be very very high. I believe Wayne county had a few done back in the 90s, cast somewhere in Ohio, but they had mopar backing to do it. There are so many different variations that guys want, it probably will never happen, if it does, where are the good race heads gonna come from? Edelbrock??? Mopar hasn't made any W9s in 15+ years...
