604 seals?

[Kenny Outlaw]

If a 604 crate engine has nesmith seals, is it legal to run at a track that has ump rules?

[Brian Gray]

Yes! The seals only apply to crate racing. Pretty sure nesmith sealing system is good in all the series. And a crate engine is legal in all the open type events.

Cool thank you.
