OK, I see the viewpoint. Kevin has already come up a long ladder already.... from just re-ringing a 318 to this more complete rebuild of a 360. IIRC, the cam plans are not for peak HP but for mid range and wide torque etc. So RPM's and balance is not as critical as in a lot of other apps. And then there is the budget.... which has already been busted a few times I do believe.....
340's from the factory romped and revved and rowdied around all over the place with the level of balance that this should achieve without any further attention. So IMHO it is quite adequate. I missed the torque plates part.... raced my rally engines hard for many, many thousands of miles without ever using one. Could have been better no doubt but when racing on a schedule, you gotta put it together sometimes and go. Each and every HP is not the be-all and end-all in many cases, nor do I consider not-using torque plate to be sloppy work.
