Quote:

The predator is considered NON conventional for Ultra and X275 is because of the valve layout. That is exactly what John Sears told me. He considers ANY Mopar head that has the EI IE EI IE valve layout to be conventional. WHen I asked him does that mean PSO casting or MC casting ? He told me any B1 that has the "original" factory valve layout is considered conventional.




So the B1-TS would be allowed then?
