Gus I run the Champion 22 I got off Ebay.Like 150 a few years ago.The 440 is built radical and never gets over 180 no matter how hot.I ran a stock 22 from a Cbody with stock shroud for like 15 years and ran under 190.It got busted when the jack slipped.was leary about the champion but in the 3 years or so Ive had it no problems.I did have to open up the mount holes a bit.But I thibk my front is bent a bit.Rocky
