Can some one tell me if a 5.7L is a long stroke or a short stroke engine? It has about 113,000 miles on it.  
  
 Is there some thing I can do to improve the pep or power, GM recommends a 265/75/16 tire and I have a 235/85/16 on the truck now, I know that will make a differance, but how much of a differance?  
  
 I also should mention that it is a 5 speed manual transmission. Thank you, Jim
