347 questions
I was recently thinking I was going to rebuild my 71 302 pretty much stock with a four barrel and headers. I recently fount what I thought was to be a good deal on a 347 rebuild kit from northernautoparts.com. Last year I was talking to an engine rebuilder and he said something about the main caps messing up or something to that sort on 347 stroked stock engine blocks. I was wondering if this was usually caused only when someone is reving there motor to 6 or 7000 RPMs often. I was only going to use mine for daily driver use you know, yeah sure maybe play alittle at a stop light or 2 but not flat out drag racing at the strip. I know that the earlier 302's had thicker castings and all, I have a 71 model block which is thicker. Would a 347 kit work fine in my block or would I have issues with main caps and such?

Do you think since Im only going to be putting a mild cam in it(comp cams .456" lift) and honestly not going to be reving it close to 5000 rpms...do you think I could honestly get 100,000 miles on it?
