Yea i would say stock being "from the factory". My original question is still valid. I wanted to know what if any gains i could get on my stock engine. If there were not any gains I was looking at the TFS kit. Instead of just getting the intake. And it looks like the whole kit with heads and all would be the better way to go.tmoss said:????
Does a stock engine = stock heads?
Or does stock engine = stock short block?
