I run a combo sorta close to that as mine is a 440/493 and I run a solid flat tappet cam thats 264 & 270 @ .050 with .585 & .592 lift on a 110 LSA. I have it in my eng on a 106 ICL. I use Hughes 1.6 roller tip rockers that have worked great for me but I run less spring pressure then a roller cam. I believe the Crane Gold are good rockers as many use them. They had a bad run some years back I believe wit some adjuster problems but there are tons of them out there being used by many. Here is clip of mine that you can hear a little but its not real good as I was not at an idle all the time on this clip. But I consider it very streetable as I love it. But I agree that is up the the one who owns and drives the car really as what they call very streetable. Ron
