I was given another 454 that hasn't been touched and decided to just work with more or less bolt-on's for now. As this being my first engine build I have some idea whats going on but not everything. I know all the parts have to work together or it's more or less junk. I looked into a top end kit from edelbrock and it says 1500-6000rpm but a friend of mine said that It would be better to go idol to 5000 as I would be putting too much stress on the motor at 5500-6000. I like the sound of a loping motor and know its in the cam but I have no idea what im looking at when it comes to cam numbers so i need some advise there. does anyone know of a bolt on kit for the 454 that would give the sound im looking for? the camaro has 3" flowmaster 40 series all the way back so the noise would be there but im looking for the lope. thanks
