Ok got off my butt and looked at the rules:
4. In the event of a repair or rebuild only a RUSH or Crate USA authorized rebuilder facility may install permitted seal tags on engine. RUSH and Crate USA Generation III (yellow) & Generation IV (green) seals allowed. NO RM bolts, FASTRAK, NDRA, DIRTcar (red or blue), Crate USA Generation I (silver) or Crate USA Generation II (blue) seals permitted. For any other sealing system, contact RUSH for approval.
5. Engines "must" be sealed in all of the above stated locations with either the "original" GM twist off bolt heads, RUSH seal tags, Crate USA seal tags, or a combination of the "original" GM twist off bolts and/or RUSH or Crate USA seal tags.
ENGINE SEALS Original GM bolts and most series seals. FASTRAK DOES NOT honor seals of engine builders. If any doubt, call the FASTRAK office. Some series have changed to their seals only or new GM bolts. FASTRAK strongly advises you to use FASTRAK authorized builders only. Most series do not require contracts or bonds so beware of other engine builders. They have nothing to lose if they get caught. The penalties are too stiff to take a chance.
Any seal other than FASTRAK or GM must add 50 lbs.
The comparison reads to me if you use an engine builder who is both RUSH and FASTRAK approved add 50 pounds and you can race in Fastrak.
RUSH as previously reported states RUSH only seals and engine builder.
Did I get it right if I did I think the info will help anyone thinking of racing in both series. RUSH says we don't need ya unless you pay only us and Fastrak says we'll accept your RUSH sealed engine if you used a builder authorized by both and add 50 pounds.
Brad, are you authorized to build and seal engines for both RUSH and FASTRAK? It sure would be a feather in your cap if you are. OR, if your not and did become authorized to also seal for FASTRAK and your engines could be used in both when 50 pounds are added for a FASTRAK race, .... I'd bet Vicky would drop you like a hot potatoe. I can see Blackshear being ingrained exclusively with RUSH, but you and other builders may not be so locked in.
Butt as I already said ugly takes many forms some not obvious to the naked eye. And if you don't buy into my skivvies totally some ugly vomit is likely to spew on your forehead in the guise of business policy.
... and for that sexually deviant young or old man who dumped on me recently here another definition:
an external form, appearance, or manner of presentation, typically concealing the true nature of something.
