Hey guys, looking for some input on upgrading the crank in my 117 twin cam. It’s currently using stock crank with Suburban Speed HD 117 kit including the throttle body and injector upgrade set at 10.7 to 1, Tman 590 Cam, Suburban Speed ported/modified heads with bigger intake valve, Bassani B4 2 into 1 exhaust and tuned by Big Boyz in Maine. I’m really happy with the power and tune but it feels like it vibrates a lot more then it did stock under 3000 rpms. I’m pushing about 125 square on R&R’s dyno with they say is on the low side compared to most dynos. I’m wondering if changing to their 5 piece crank would be worth the investment and smooth it back out. I don’t want to do any more motor work for power just longevity and smoothness. I’ve also noticed my comp knocks and is noisy at idle since the build. Thoughts? The crank is pricey, but I’m local to R&R and know they make a great product and can do the install as well. Any input is appreciated:)
