this doesn't sound like any normal lope i've ever heard is what i'm concerned about. at idle, especially after it starts getting warm, the rpms will fluctuate from 600rpms to around 1700rpms. i know it's a big cam and all, but that's a huge jump, and it takes awhile to even out once it comes off of idle. and i still do get dead misfires at cruising speed. idk, maybe i'm just being too paranoid. it was simple to put into time, i even had the heads off and saw cylinder 1 at TDC.
