This blower made 15psi on my 331 setup. People will hear you coming from blocks away. Includes blower, blower bracket, inlet tube with Anderson Power Pipe and discharge tube with race bypass, 2 pulleys 1 belt, tensioner and crank pulley. The blower is nice and tight, has the Race M bearings in it and I replaced the seals last year. I'm including a Stage 3 Programmable Snow Performance Meth Injection kit. $1500 for all. You pay shipping.
