Close. It's actually more like 160 once all of the systems are optimized. Compression, porting, carb, intake and distributor work. Nothing radical, just typical race-prep attention to detail. Everything from the water pump impeller to the carb air horn is being massaged for maximum performance and minimum weight.
Weight...I've taken everything into account, INCLUDING me and the clothes I'll be wearing and come to 1425 ready to roll.
