[turbo2387]

considering the benefits of swapping cams in my 160 pump. street truck. mid 600's. looking for efficiency not max fuel. I don't need a 13mm with 850cc of fuel. 450-550 is plenty. the truck struggles with RPMS above 3300 in OD climbs but slow. 55psi fuel pressure when the second pump kicks in. 40 off boost.

so is there anybody out there running a 160 or 175 with a quick rate cam? pros cons? being able to lower the timing would be sweet as the truck pulls occasionally. any input is appreciated.

thanks
