The owner of a 1998 Jeep Wrangler had several questions about the use of a CompCams 252H grind camshaft in a Jeep 4.6L stroker inline six engine build. His engine core is a 1998 Jeep TJ Wrangler 4.0L...Here is our exchange. My comments are in red:
Keith M.: I’ve seen some posts, including on Comp Cams’ site, that say the head on the ’98 has different size valve stems than other years and that cams that will work on other years won’t work on this one. I’m pretty confused by what seems to be conflicting and unreliable information.
Moses: I’m not clear why there is so much confusi
