As I think about it, this combination might work out well for you and have some added benefit. The 4.88 rear end will allow for quicker acceleration out of corners, with the cost of lowering top speed for each gear on the straights, but being able to approach 9,000 rpms will make up for that and decrease the need for an upshift at the end of longer straights.

The combination of the 4.88 rear end and 15:1 compression ratio will probably result in quicker de-acceleration when you take your foot off the gas and this may result in you being able to take corners with just a light lift that previously required some braking. A quick lift and turn in may be all you need, or at least you might only need lighter braking than previously. Anytime that you can eliminate some form of driver input, such as shifting or braking, you will lower your time.

Looking forward to hearing how things work out once you get it all back together.
