Hello everyone, I was looking for some answers and was hoping to find them here. I have a 2002 GT with over 150,000 miles on my engine. I want to get a forged bottom end without spending a ton of cash. So I have narrowed it down {I think}, to swapping the bottom end of a much less used 99 Cobra. I plan to use the standard 2 valve heads with possible stage 2 cams. My question is will this 99 cobra short block mount directly with all my stock setup. I do hope to supercharge it someday thus, the reason I want to go forged bottom end. But for now I will have to settle with 75mm throttle body that I currently am using. thanks for the help.

Do you have a "trusted" machine shop? This may prove the difference between success or failure. Why? Because even IF the parts will interchange, HOW would you know if the measurements are within tolerances?
When I rebuilt the GM 3.5 I had a machine shop clean and measure all of the parts. That way I knew before assembly that all bearing sizes were within "standard" sizes. In that way I could do the labor to assemble with a reasonable expectation it would run when put together (it did). IMO the services of the machine shop were invaluable.
