Force-Fed 383
We ordered an LT4 conversion kit from Pace Performance Warehouse, which included GM's famed "Hot" camshaft, but like the 383's original pistons, the Hot cam isn't really suited to a supercharged setup. According to engine builder Eric von Hentschel, the Hot cam's exhaust ramps are long and the lobe separation is too narrow. "Most of the mixture would be burned in the headers with a blower and the Hot cam," he said.
