I need engine help

xsamis

So my thing is i dont no any good shops that deal specifically with my engine, i have a shop that does good work and i take all my cars to him so i trust him, but he specializes in dodges, all he does is dodge, i was thinking of taking it to dynosty in Kentucky but thats a 6 hour drive, and im scared to drive a car with rod knock that far, i was thinking of putting a Z1 built lower end on the car and hoping it would fix the issue, i drained the oil and found only 1 quart of oil in the car, so im scard if i pay 3000 for a built lower, my upper block is messed up, thats were im lost, do i take it 6 hours away to dynosty or to my shop down the road? And if soemthing needed to be replace i was trying to put better internals, bearing etc etc, lower wise, but i dont no if i would have to have the shop tear it down completely just to replace something like that, or if i would have to replace a whole set not just one peice with aftermarket parts that can hold more power, thank you guys for ur response im totally lost and miss my z );
