Some things swapped out the day I brought it home (from the Grand Sport) were the: I did not have time between business trips to clean it and take pictures as delivered but found my car's twin at Gulf Coast Motorworks, so these pics are exactly what my car looked like the day it was delivered: EXCELLENT LS7 article on the Camaro forum HERE and on the LS7 heads HERE. Hib Halverson's DIY wiggle test guide is HERE. GM's response to this LS7 Valve Guide Issue (archived HERE) and a thread with links to a map of shops that perform the wiggle test to determine if valve guides are within spec HERE (interactive map HERE) as well as registry links to those that have had the test. Outside of that I will just bite the bullet and get the heads addressed before the warranty expires. Some worry about the LS7 valve guide issues, motor failures still seem to be occurring after "the fix".no worries for me, 100k mile warranty should cover anything that fails. So how does the 427 compare to the Grand Sport? I thought on paper it didn't appear to be a huge difference but the torque, the sound, the feeling is something numbers on paper cannot explain- if you're happy with your LS3 don't test drive an LS7 It seems like a much angrier, race oriented motor- PERFECT for me. The Lear Car2U remote has replaced Homelink and it can be painful to program- I had to buy another receiver from Liftmaster for my Genie opener to work. Press release is HERE, Hero Card is HERE, website I archived with videos is HERE. The 427 model was released in the final year of C6 production as a send-off of sorts, only 2552 427 models were made for the 2013 model year, a convertible with the LS7 engine (Hib Halverson's excellent LS7 write-up HERE) up until this model only available in the Z06. That said, I made the mistake of not double checking all of the boxes in the car when I turned it in and left my iPod and 64GB flash drive in the center console, never to be recovered- draw your own conclusions. Fred and the Jim Ellis sales staff were great to work with and I would not hesitate to recommend them to anyone looking for a Corvette. My 2012 Grand Sport was returned to stock and traded in for this car. This car was a 60th Anniversary Package car sans stripes with black wheels- exactly what I was looking for. This 2013 Corvette 427 (1SC) was purchased new from Fred Gamble at Jim Ellis Chevrolet. Click on thumbnails below for larger pics.
