I would also like to urge a new Black Magic engine! I was an importer of Rossi when the Black Magic was out. I brought over many Rossi engines during that time. I ran the Black Magic, and was impressed with it's unmatched machining. For those that have not had the pleasure, when the BLack Magic was new, you could spin the ngine over without resistance with the plug removed (virtually NO pinch!). Put the plug in and you could NOT turn it over without GREAT effort! All compression and no friction

. Some of the guys that bought them had some issues with tuning, but I found them to tune OK. Not as easy as some, but not really problematic. However, they were not free of problems. Many had catastrophic rod failures fairly early on. My engine went 7.5 gallons of fuel through it before you could turn the engine over with your finger, while installed in the chassis! The Rod went shortly after.. I inspected all the engines that had rod failures, and am certain that the issue was a clearance shortfall between the rod and piston skirt. All rods failed at the point where the rod lined up with the bottom of the piston skirt. Removing a small amount of material from the rod solved the problem.
Overall, I was a huge fan of the lineup. One of my friends bought a Silver arrow from me, and it went a very long time before it failed (he is a terrible tuner and is known for killing-off engines before there time!).
A few years later, I was no longer running off-road and needed a new engine for my 1/8 on-road. Picked up a LS1 from the importer at the time. I was appauled at the crudeness of the engine! It was like going from Ferrari to Yugo! The machineing looked very amaturish compared to the work of art that was the Black Magic. It's performance was as poor as the workmanship. It is back in my car now, after spending a couple years as a paper weight, and picking up some rather radical mods.
Anywho.. I would very much like to see a return to the precision and artwork of Black Magic, Silver Arrow, Marinello era.
I would really like to have a new Marinello 2.0!
