Ebay has a lot of portable China Spray booths that run from $1000 to $2000.  Most are a little more than inflatable bounce things. The one at the SEMA is manufactured in Texas by Mobile Environme

I placed a Sanden SD-7B10 A/C Compressor where you put the alt.  Made similar 1/4" plate mount brackets.  Have yet to make my spacers to align compressor and idler pulleys.  Nice work as usual.

I went with truck spacing accessories and was able to fit a truck alternator AFTER clocking the casing 90* to move the positive post away from the motor mount. I also have a sanden low mount using dirty dingo's low mount and had to notch the motor mount location.

Engine Compartment Modifications-


     I forgot to post the Alternator that I utilized-NAPA #272-4717 104 AMP  Alternator( cost $130).   I originally tried to install a 140AMP GM one but it was way too large to fit in the bottom

driver side of the motor.    I think 104 AMP is sufficient unless I install an Electric Power Steering Unit.   The NAPA Alternator has a Lifetime Warranty and 104 AMP is widely available.




AIr Intake-

    My Crate LS3  6.2 Liter motor did not come with a Air Intake  Setup so I had to fab

one.   Spectre Performance had a 4" Stainless Tube ($75), 36" 0fn 4" Flex Tubing($32)and 4" Right Angle Rubber Elbows(($24) for basis of my system.



I didn't want my Air Inlet to breathe Hot Engine Compartment Air so I fab the system to get Cold Air from just behind the grille.


Had to enlarge the hole in the Core Support to accomplish this.


Also, had to "Tap "  the Wheel Housing to get about 3/4" clearance for the Duct Hose.



Used Shears to Trim the Sheet Metal Plate for the Duct Hose.

Trial Fitting of the Flexible Duct Tubing.   I created a Steel Metal Duct Plate on the Core Support to hold Duct Hose and Air Filter.IMG_E3471.JPG.a246a70c92d8d4a56a226dbca3c7b281.JPG
