    • Well, it’s been awhile since I’ve posted anything. I finally had to install a new optima battery after 8 years. Getting ready to load it up and take it to the new garage. In the past year I have been going thru every inch of the car checking and replacing stuff from years of hard racing. I re-engineered and machined new arms for the rear suspension from my last design making it better and yet more stronger. I’ve been installing all the new body panels I made to improve aerodynamics and drop drag coefficients while leaving enough to suck to the track and stick. Although, I did remake some parts to improve on fitment.       So, next on the list is final paint and finally getting it inspected so, it’ll be street legal again probably by the end of may it’ll be back on the streets and on the track again creating havoc !!         
    • Hello,    This is my first attempt at putting the LS 5.3 motor down into the engine bay of the Cat.  Plainly, the engine needs to be and can be lowered somewhat and the Holley 302-5 oil pan will still clear the steering track rod.  This "Builders Mount Kit" from the ICT Billet company provides a lot of front to rear adjustability and the two dangling steel plates will be trimmed down by me to lower the engine. I will likely cut these plates down in quarter inch or maybe half inch increments to sneak up on a proper fit.   And as you might notice, the rear plate on the passenger side of the engine appears to need some notching to clear a brake line.   This engine is not the engine that will be used to propel the Catalina.  This one is merely a testing and fitment mule.  However, once I'm satisfied with the placement and driveline angle of the engine and transmission, these dangling steel plates get welded to the front frame crossmember and the large bolt in each stand gets removed to allow the engine / trans to be lifted out.   I'm also now very curious if the original LS engine exhaust manifolds can fit between the frame rails and still bolt up to the heads.  Setting a head onto each side of the motor will be my next activity to see if the manifolds will fit.
