I did it on a hot 406 sbc gmc shortbed , back when they cost $90 something , I made some alum. quick pins to separate the hoses from the firewall quickly to remove the breather assem. when working on the engine , worked out very well .
If my throttle body wasnt up in the hoodscoop , I would have done it on my 68 fastback , as I really didnt want a scoop .
