Any engine shop that I'd actually take it to is backed up until January so I'll be selling as is.
I'd at least pull a valve cover off could be as simple as a broken valve spring an easy fix.
The shop should have been able to find out why there's no compression with a couple simple tests.

1987 Camaro Iroc Z 5.7L (Best offer)
- 89k miles
- 4 speed auto
- new 700r4 built for 600hp
- Flowmaster exhaust
- Black leather interior
- T-tops
- New front suspension
- Rebuilt differential
- New oil pan
- New LED Headlights
- New A/C compressor but needs hose
- ~ 1k miles on gforce comp 2 tires

Currently there is a cylinder 6 misfire and no compression in that cylinder. Runs fine through town but higher speeds there is a vibration. I'd fix the the issue but right now I don't have any extra money and we're trying to sell before winter. The car is located in Northern Virginia.
