Other Important Engine-Blueprinting Issues
Engine building is an art to be learned and perfected over a lifetime. This is what makes MCE Engines exceptional in a trade full of professed engine builders. Marvin will tell you "there are engine builders and there are engine assemblers." Engine builders think beyond the surface. Good engine builders examine every detail, especially the stuff most of us never see. Here are a few examples.

Lubricate And Secure
When Marvin was building Blair's 427W, he gave us a crash course in thread lubrication and security. We want bolts to remain secure, and we want them to glide smoothly into place to achieve accurate torque readings. Never install and torque fasteners while dry. Always lubricate threads. When you are using a thread locker such as Loctite, the thread locker acts as a lubricant during tightening. Then, it cures and secures.

How Much Grunt
Marvin used Desktop Dyno PC simulation software for a look at how much power Blair's 427W should make:

RPM HP Torque
2,000 188 495
2,500 254 533
3,000 320 560
3,500 396 593
4,000 470 617
4,500 534 622
5,000 576 605
5,500 590 563
6,000 601 523
6,500 577 466
