Things you did/upgraded that surprised you how helpful they were

Sold the 727….. now I just have to rid of both 8” converters.
Did you list the converters on here for sale yet?

Things you did/upgraded that surprised you how helpful they were
On a street car, single to dual plane, AFB to AVS (OE), leaving the orange box ignition in the garbage can.

On the street/stripper, upping the gear ratio, wider/stickier tires.

(Overall, never listening to the crowd on what I can and can’t do. Coupled with! The amount of misinformation and idiots that read the internet and parrot the idiocy of why there suggestion will work.)
