Just absolutely pointless IMO. If you want to be different, buy a LeCar and swap in a Cobalt SS motor.
if its so ridiculous then why do some many grand prix GT'* do the top swap
they do it because its cheaper then pulling ther working L36 and replacing with an L67...
I also hear they need a SC pulley thats about the same size as a HB pulley to make up for the compression difference.
If you wanted higher compresion, couldnt you just shave the heads a touch while using an L67 block, thus getting the stronger internals?
