UPDATE March 2010
Okay here is a bit of an update.
After doing some research, I know now that the LQ4/LQ9 block are the same design. The only difference I have found between the tow is that the LQ9 block is a high nickel iron block which makes it a stronger block. Having learnt that I will be goinga head with the LSX block because we will be running at least 20lbs of boost with the F-1R Procharger. I prefer to over build simply in case I choose to increase the boost somewhere down the line. We should have the LSX block in the shop by the end of this month.
Next, the work has been done to the fender support structures. That work gives me much more clearance between the bottom of this support rail and the top of the tires. I am really pleased with Resnick's workmanship as these parts look and feel stock. 99% of anyone would not notice they have been altered, especially if they weren't comparing to another Cobalt side by side.
Now that this is done, work is now starting on the custom headers. I hope to have pictures of those monsters later next week.
