These are not truck manifolds, which stick out way too far to the side. These are aftermarket Chinese castings. Yep, I am aware, I have a set of those on the shelf I bought just to have because I do a lot of LS swaps. Just saying that a lot of guys turn the truck manifolds around so they face the front if it is too tight to the back, cut off the factory flanges and weld on V band flanges with the crossover pipe up front.
It makes sense to have the crossover at the front if the turbo is going RF of engine bay. Shorter run (heat = energy) and leaves room for the downpipe to go down and back. Jim, have you plugged in numbers (weight+ET = hp needed) yet? You mentioned 3000 lbs and 9s. this says 600 HP will net a 9.96 https://xcceleration.com/et.calculator.html
Playing with mounts again. Trying to find where the engine wants to be, and how to support it there. I think it's pretty close, within 1/4" at least.
working on mounts. This is one of the frame brackets that held the original motor mount. I cut off the horizontal part of it that went to the mount for the inline engine, at about a 45 degree angle, and welded on a plate to build the new mount off of. It'll all make sense when it's in the car...but at least a little progress is happening.
no engine plate, I'm going to try stock Camaro mounts and see how it works. Might not work, but I'll only be out $25.
These work pretty good for custom installs, I make new plates as needed if the included ones are not long enough. They are on ebay and amazon pretty cheap.
