Hey Guys. Just looking for some opinions. I知 installing and LS9 into my 74 C3. I have a complete LS9 and T56 magnum. I知 wondering on what to do about engine harness and such. Should I run the

Chevrolet Performance 19369382 Details kit

or is it easier to get a custom harness built and go to drive by cable? What痴 everyone痴 thoughts ? Any advice / help is appreciated

thanks.

 

 

Custom harness will always fit better than an off-the-shelf version

FWIW, you'll need to go with an aftermarket controller to use DBC. All gen IV 58x engines (anything 08+) are DBW only with a factory ECM. There are work arounds such as the ligenfelter box, but nothing will directly switch

 

Speartech or Howell Fuel injection would be my choice. ECM and harness.

 

I used Speartech, and had great experience, and the customer service is top notch!
