Re: 69 camaro ls conversion
I just installed an LS3 and Tremec 6 speed. I used Holley motor mounts, Holley Blackheart long tube headers, and the Holley Crossmember. I have a new PS gear box from Detroit speed. I did convert to Vintage Air with their front runner kit. Everything fit great and install was very easy. One thing to be aware of, that Holley does address, is that if you have a stock subframe, the headers are different than if you use a DS subframe. I installed a DS quadralink, so I have to make some modifications to their header back system to make it work. Minor, but not out of the box fit.
