How do you tell if a engine has good compresion?

i have a 1987 chevy caprice, at first i could burn rubber, and go really fast. then my rebuilt trans messed up, and ever since then i ha vent been able to burn rubber. i changed my wires,plugs,distributor cap and rotor. i have been getting backfire or misfire ever since i swap out those old parts for new ones. how do i tell if my engines compression is good ? but i didn't experience a improvement in power, can the trans keep me from burning rubber or getting the full power from the engine ?How do you tell if a engine has good compresion?
Buy a compression gauge, remove one spark plug and insert the gauge, turn the car over and check the reading, compare with proper compression for the engine and get fixed where needed. If you need help, take it to Auto-zone and they will help you. Good luck!How do you tell if a engine has good compresion?
If your getting back fire, check your firing order first . you have a wire or two swaped. then give it a try .How do you tell if a engine has good compresion?
make sure you have the plug wires on correctly. as few as 2 wires on the wrong plugs can cause a back firing issue.

to check your compression you need to buy a compression tester and pull the spark plugs to use itHow do you tell if a engine has good compresion?
My chap says you have to do a compression test. Go to Halfords and buy a compression gauge and test each cylinder via the sparkplug hole. They should all be of similar readings within a few degrees. If there is a major difference in reading for each bore - urgent garage repair needed.How do you tell if a engine has good compresion?
no make sure all the connections are absolutely correct you may have put the wrong plug on the wrong cylynder which would cause misfiringHow do you tell if a engine has good compresion?

take it in if you dont know what you are doing
