I went w/ a 292-10 solid roller in my 505"/440. had the same came in my 406 sbc -gmc, was a hot sounding darn good running street cam in the 406. In the 505 it is a pussycat, doesn`t sound too wild at all. haven't much seat time , or running time on it, as the car isn`t finished yet. for what ever that`s worth !----wonder why mopar guys think a cam is a big one , when most chevy guys run bigger killer cams compared to ours ?!---- p.s. , the only thing that looks a whole lot diff., (going on memory here, not spec sheet), is that mine has 254 and 260 @ .050---------bob
