Any reliable corvette shops in the CA bay area?

[AyeRon]

Hi, everyone.

Im new to the group, and as the title suggest, I'm looking for any recommendations on mechanics/shops in the bay area that specialize on the LT5 engine.

A little backstory: I picked up a 1990 ZR1 that ran great to my knowledge, until I got back to the house and noticed that the secondary vacuum pump was continuously turning on and off. I took it to my mechanic and sure enough they found a leak. They used a smoke machine and traced is back to the Secondary Port Throttle shaft seal. Unfortunately, the seal is behind the bearing, which they do not know how to remove and they've chosen not to proceed. They'll be putting everything back together for me to pickup.

This leaves me with a few options:
- I find another mechanic that specializes in the LT5's uniqueness.
- I tackle the job myself and risk turning my running car into a parts car
- Decide to drive her at half power FOREVER (not happening)

Any advice is welcome and greatly appreciated. Thanks!
