looking to build up my 2001 chevy 6.0L cast block-heads motor for a long travel sandrail this motor is out of a truck and has 70,000 miles on it and runs good just want to get alittle more power out of it was told ls6 aluminum heads and a cam would produce somewhere around 435hp. is this true if so what cam should i do and where can i find it and where would be a good place to find ls6 heads. Thanks in advance!
