347 what rods

What rods are te ones to stay away from on 347s. I know one of them causes wrist pin problems and burns oil. I'm in the process of building a stroker motor and don't want to have to rebuild it again shortly.

This oil burning problem has almost nothing to do with rods. It has to do with the lower oil ring spanning the the wrist pin hole. There is one exception that I know, Coast that uses a 5.315 rod instead of the 5.4 which in effect moves that ring higher. In my opinion, a 331 (actually 332 ) stroker with a 5.250 stroke keeps the oil ring free, has a better rod ratio and usually a better engine for survivability as far as skirt wear and oil burning potential. Either an I or H beam rod will work just fine as long as you can stand the cost. Do not use an aluminum rod if this is a street driver

Just as an fyi i had a friend that built a 347 with trick flow heads and good cam. When he was done he dyno the car and made 268 at the wheels. So be very realistic about your build. If you want a solid 300 hp 347 is the way to go but if your looking for something more than that better think boost or 351/460.

Now he did not go with higher compression, engine builder told him it would knock so he didnt raise the cr at all over stock.
