My son has an 86 Cutlass powered by a 355ci Chevy eng, manual trans and a 9&quot; Ford rear end. His class is called Street Stock but is more like a late model class but with a stock body.<br /><br /><img src="http://img.photobucket.com/albums/v425/Peddler-1/06-16-2007115833AM.jpg" border="0" class="linked-image" /><br /><br />Jack&#39;s car is a 85 Monte Carlo in the Pure Stock class. Again a 355 chev w/ manual trans and a GM 7 1/2&quot; rear end. This is the one we&#39;re working on today. <br /><br />There is a performance difference between the two cars with the street stock being quicker. The two cars look very simular. I&#39;ll try to post a pic of Jacks car tonight when I get home or first thing in the morning.<br /><br /><br />Thanks for the intrest.</b></i>
