Do LS1s have "matching numbers"?
Do LS1s have "matching numbers"? You know, like the old muscle cars have the block #s match the vin #s or the head #s match anything or are they just any pair off the shelf. Im wondering because Im doin a H&C package, but if the #s match my cat, the Ill buy a used set of heads for the core. TIA.

Re: Do LS1s have "matching numbers"? All of the parts block, heads, transmission, etc. just have part numbers. They have no specific number to the vin number. I called a person at GM to find this out because they had to replace my tranny and i didnt want non-matching numbers.

Re: Do LS1s have "matching numbers"? I kept my original set of heads from the last car and it was a damn lucky thing b/c I had to have something to put on the car so I could remove the ported ones after the flood. <img src="gr_images/icons/mad.gif" border="0">
