The 224 may max performance, but isn't it going to kill my towing? I where I live I've got foothills and tow over a mountain pass or two, and can afford to lose alot of low end.

 

I honestly for once agree with comps recommendation, a 220 duration would be the biggest Id put in there.

 

thanks slow

 

112 vs 114...
For what you looking to do, get a cam with less overlap, the more overlap you have the more you'll hurt your low end. Overlap is good for making power on the top end since the intake velocity at those RPM's is enough to overcome the exhaust pressure for that slight moment that the two valves are open together, also helps scavange any remaining exhaust out of the cylinder. However during Low rpm driving the intake velocities are not enough and you end up with some intake reversion which is why you hear your motor lope.
