71 Camaro Pricing

My uncles trying to sell his 71 camaro and was wondering about what to sell it for with all the modifications, as it is basically fully set up to be a drag car.

It has a 454 back block with a seemingly well built turbo 350 and 4.11 gears.

It's tubbed with wide drag tires, but they need to be replaced due to their age.

Full roll cage, racing seats and 4 point harness.

The body is in good shape, but the primer will probably need to be sprayed again.

Don't need an exact amount, but any guidance would be greatly appreciated.
