ok so i got the idle almost fixed, i replaced the throttle cable and all is well (around 900-1100 rpm just needs tuning)

but ive got 6k burning a hole in my pocket and would like to upgrade this thing, i have a feeling i should get my old 82 engine rebuilt, and ported, as i have no idea how many miles this 83 motor has on it but it feels pretty tough

k so what should i get/ do, and wheres the most economical place to have my engine rebuilt, as i dont trust my technical skills to rebuild it

 

It is super easy to rebuild these motors. I am sure even my grandmother can do it (seriously).

Honestly, best bet for the money is TII upgrade, and suspension.

 

Intake (I recommend a 465CFM Sterling), exhaust, rebuild/port, suspension (RE-Speed) rack and pinion conversion (also RE-Speed) bushings, and some wider wheels and grippy tires.
