Amsoil Convert! 150 seat 400 open Looks like new!

Wow! We recently ran a flat tappet BB Mopar in the Amsoil Mopar Muscle Engine Masters Challenge ( see more in general section "Home from Amsoil Challenge") We had to tear down after the runs for tech inspection so I got a good look at the cam and lifters after over 12 dyno pulls--WOW! We ran a Bullet flat tappet cam , 1.6 rocker approx .650 lift and used the Scorpion lifters with the EDM oil hole. I broke the engine in on a test stand with the inner springs removed--ran it about 45 minutes. I set the final pressure 150 seat and right at 400 open. The cam and lifters looked brand new! We used the Amsoil for all break in and runs--yea....I know its synthetic...I know Joe Gibbs and a dozen others make break in oil. I have been a Mopar engine builder for going on 30 years and have been whacked just like you with ruined cam lobes etc--these past 5 years have been a nightmare but...I have to say that the Amsoil worked better than anything I have used since the way back days when oil was real and parts were USA good. Hooray for a great product!! The stuff works!!!!!!!

currantly running amsoil syntetic air compressor oil in my power glide ,flashpoint is 200 degrees higher than atf, everything looks great!very satisfied

Which Amsoil were you running? They offer so many now it's kind of confusing.
