Hello all and Happy Holidays! I am looking for ideas to increase performance of my LT4 Nova without getting too deep into the engine (pistons, heads etc...). I know I can add an underdrive pulley, upgrade the supercharger with a Whipple or Magnuson, the cam with a Ligenfelter or the throttle body with a mamo ported throttle body But what I am hoping for is ideas I havent seen yet. In searching for upgrades for the LT4, it seems it's very limited or I am just not searchging the correct terms.

Thanks
Jim

I brought the car to National Speed in Wilmington NC (near me) and they did do a tune and dyno but I am planning on the pulley upgrade as well. I know when I do that I will need it tuned again due to the change in RPM and more air flow from the supercharger.

Find someone that tunes them locally.

Pulley and a proper tune will go a ways before you need to get into injectiors, cam, throttlebody.
