What we have found with the Webers is that you have to watch the over lap on the camshaft which will affect the signal to the carburetors at the higher rpms. Webers tend to back fire through the carburetors because of the short intake runner length. I have run sevral FE 482 engines with cams in the 242/248 range at .050 with about .600 lift and a 114 lobe seperation with no problem. These engine made power to 5700 to 5800 rpms with no problem. I have found them to make more torwue than a good 4bl but a little less HP at the top end. Good luck with your project. Keith
