Engine Break In Question. - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I am putting my new 350 in the truck tomorrow and I got to thinking. If if is 20 degrees outside would it be better to use straight 30 weight non detergent like everyone says or should I use a 10 or 20 instead. Also If it is so cold do I really want to rev it to 2500 immediately or should I let the engine warm up at a slower Idle to let the oil start to flow better before I really rev it to ensure that the cam gets enough oil. I am pretty concerned about this. I know that this initial break in is critical. Any suggestions? Thanks.
