The Navarro seem to have larger chamber volumes than many other choices so you may not have an interference problem. Look at pages #4 and #12:

Looking for someone to comment on how close the four cams I compared are. The Mercury being the least aggressive.

Since I've had good luck with the Crower regrind that mimics the Isky 88 I'm going down that path.

Good choice!

The only way to compare camshafts and other aftermarket Power adders is: to run them all under similar conditions. To pick a cam with similar numbers, use the one with the most area under the graph. Usually +/- 30degrees. The 1007B would win that comparison due to the quicker lift rate. Now thid is allot of BS fore most people and you choose the one you lie best, and that works for me.

JMO but smooth idle tall tires with od on 3.78 I would chose the late Mercury cam.
