hello, i have a chevy 350 bored and stroked to 385. it was just recently built by my dad and i and i am still breaking it in and tweaking on it. It has fully balanced bottom end and some double hump heads that have had 3 angle valve job, ported, everything with around 12.9 to 1 comp. Went with the comp XR292R Mechanical Roller cam, 830 holley double pump, 3500 stall, and 4:10 gears, full msd so i know its getting good spark and pretty much anything you could think of (nothing spared) My question is what is your suggestions for breaking it in. I have already drivin it about 50 miles and not got on it very good yet just little revs here and there. Its smoking a little and oil on the plugs i just wasn't sure if the carb was washing the rings for being a little too big or if it was just going to take a little more driving to seat them. I am just worried because we honed the cylinders and put that dry seat film on it with the total seal rings. I didnt think it would take that long to seat the rings and it seems like its worse now than when started the first time, any advice on something im not doing? Not sure if higher horsepower motor needed something different to break in? thanks
