Re: Cylinder Heads for 327
When asked what would be better (RPM vs e-tec 170) I got this response from Summit tech department ...
It really depends on the profile of the cam you are running. The E-tec likely will be a better match for your 327 due to the smaller runner size (170 cc) if you are using a cam that does not exceed 5,500 rpm. But if you are more in the range of 6,500 - 7,000 rpm, the RPM series head (185 cc) would be the better choice. Both are very good heads and will work well in comparison to a stock head. But if you are looking to optimize usable engine HP, the cam profile will be critical to making a selection. Thanks, Mike
Since I'm running the RPM cam (good the 6500) could the older style RPM heads be better? Does this make sense?
