Planning on upgrading OPG & Sprocket soon. Don't mean to sound silly but do these gears require a break in period?
With the wick turned up and running higher rpm, that weak link starts to surface, but if it's a weaker link than the rods, I'm not sure. It's certainly easier and cheaper to install these than a set of forged rods. If the gears shatter, the engine is done and these are not cheap engines to rebuild. Anyone that builds their engine goes that route, but I haven't seen that many install them in otherwise stock engines. I'm sure it can't hurt anything. BiminiLX comes to mind on breaking the OEM set in his 5.8. Realize the 5.4/5.8 has a .5" more stroke than a coyote too, so crank vibrations will come in at lower rpm than the shorter stroke.I know thees are highly recommended on the coyote motors but are they really necessary on the GT500's?
Good question Catmonkey.....OPG on a build is a no brainer. Maybe I should've started the thread asking who has done OPG's on stock block motors with just FBO's and why.Beside J's failure, who else has had OPGs go south?
