Now you know my pain with the Morrels in my small block. laugh2 I ended up putting the Comp solids in my truck but they were twice as loud. Fine for a race car with open headers but not a street driver with a quiet exhaust. I put the Morels back in and gave it .085 preload instead of the .060 I had previously. Not quiet but not too bad. If I ever put a bigger cam in it I'll try those Comp lifters. Thanks for the heads up, just wish it would have came sooner. laugh2
