If it's not a full race motor and your just driving the car for fun don't worry about the crossover. Mother Mopar didn't think it was a problem and thousands of them are running around with it open as designed. My GTX has a fairly healthy 440 and mine are not blocked and no problem with fuel boilling.



When Ma Mopar designed these cars/engines fuel was completely different than it is today...

You don't want to block the heat, that's fine, the fuel isn't gonna get any better & in California we already get what you will be getting... But we also have a warmer climate which amplifies the problem.. Personally I see the intake being off right now as an opportunity to improve the future starting/driving of thew engine...

BTW I edited my above post with the pt #


Oh and as far as the engine temp with the crossover blocked, it actually runs cooler..
