318 wont rev above 5,300

well as said above... check you valve springs, like was said in another post with boost you have to figure that much spring pressure is taken out of the equation...

as for me im sure that cam you bought is not a boost profiled cam and those springs either... so i would look into that first...

second, did you have the dizzy curved? are you running "lots" of total?? maybe to much...

also fuel, running out of it? fuel line size ect

tell us your combo plz!!

P.S. you took the chance of running the car when you knew there was a problem?
