IMM Engines 408 build

After we dyno an engine, I always listen to them, with and without ear muffs...especially around the valve cover area. There was no noise at that time...and if there was, this engine would have been super easy to fix a lifter issue, as we removed the intake manifold and shipped it without it (Marland was using his intake). So that would have been really easy to fix. Sorry for your troubles, but honestly it was fine when it was shipped. Don't know what else to say....

You can put your earmuff right on the valvecover for a quick hear see but I use a stethoscope numerous times throughout the course of a dyno session and if it doesn't sound like a sewing machine under the covers-somethings wrong. Even a solid cam that is adjusted right and happy will sound like this. p.s. I'm starting to hate hydraulics for anything but the most mild of applications. So here's Brian covering all of his bases, dyno test and all. He ships the engine and customer installs it and bam minor but annoying problem right out of the gate. Yup seems about right. This trade....this trade. J.Rob
