You're clearly an experienced engine builder, with a knowledge base beyond most, but i think you're being too critical of ALL crate engines with your description. This crate engine isn't meant to have everything scrutinized, or to be wailed on every weekend at a drag strip in a car with 4:56 gears. There are Race engines, and there are street engines. This is a street engine. I understand your point about over stressing components if you break a driveshaft...but can that not be said of every engine? especially one that is never intended to function at that RPM? Thats why we have aftermarket ignition systems with rev limiters.
I'm not arguing with your beliefs, or your opinions. just pointing out that just because this doesn't come with a super involved build sheet, and you don't know a part number of the cam bearings they used...it does not mean it's not reliable, or not a good street engine.
In my opinion..95 percent of customers that would purchase this engine, would never take it down a drag strip, would never even have an interest in knowing a crank PN, and would just install it, drive it, and have some fun on the side streets.
If you want something with forged internals, and good for 7500 RPM, and to know every single nut and bolt that went into it. Then you build one yourself, as you have the knowledge to do. Or you look at something with the components you're interested in.
Also something i'm going to point out... You can find anything you want to find on the internet. Including people who love crate engines, or hate crate engines. I have yet to see a RECENT example of a blueprint issue. Everytime someone blindly states that "blueprint has issues...google it" i ask that you look at the date on those post. Were there ever some issues? sure. Have I (that sells them regularly) had any in the last 5 years...no.
I can only speak from my experience, and my knowledge of their products. Again i'm not looking for a fight here. Blueprint just deserves a little credit, and I'll defend them in their purpose, and thats a great street engine.
I compare it to walking into a dealership and buying a car...Does the average consumer demand to know what Bearing tolerances the engine had during assembly before they drive it off the lot? No... In most cases they don't even know/care what rear end gears are in it. Thats a mass produced crate engine, vs a home built, or race build. Does its job just fine, with no issues, and with smiles on faces.
