Whats the budget?
Whats the End goal?
Heads/Intake/Cam 302 should get you around 105/8 trap speed. By far your cheapest option.
Could rebuild it with a 347 stroker kit, get a bit more
Can go with a 351 based motor. Stroke it to 408, be a pretty fun NA car.
The Coyote swaps can get pretty pricy, especially if you are not doing the wok yourself. Lot of things would have to change for that.
