Ok I got the car all fixed up and finally put the Dorman intake and Holley 90mm throttle body on the car.
If anyone is putting a Dorman LS2 intake on, it’s a bit of a fiasco.. but it fits and works. You can hack up the firewall a lot for clearance, but I close to lightly modify the firewall lip and notch the back of the intake to fit around it, relocate the MAP sensor back there, and it packaged pretty well. I used a Motion Raceworks adjustable throttle cable and mount, the OE throttle cable bracket and cable was not going to work well with the Holley TB. I had to clearance the bottom of the TB, intake mouth and water pump to get everything to clear.
You can see the notch I cut in the pics below. I was going to remote mount the MAP sensor, but I ended up removing the brass elbow and mounting the MAP sensor in that hole. I used JB Weld Plastic Bonder to secure the aluminum into place. It sits in some notches I made, so even if the JB Weld failed, the aluminum pieces can’t fall into the manifold.
I threw all that on and then went to LSFest West in Vegas and happened to run into
@V8-rx7 Anthony. That was a cool surprise, I haven’t seen him in about 5 years. He was in a loaner Corvette Z06

I did the AutoX on street tires since I drove the car 90 miles there with my dad to road test everything. The car did well. I’m going to be more serious about the Autox next year.
