I am pulling my 235 Chevy motor from my 1954 Chevy Bel Air. I did a compression test and a coolant test before I pulled the motor. Based on the results I didn't bother to do a leak down test. At this stage the motor is pulled apart enough that I can't run more tests. I want to share the results of the test with the forum to get some feedback. Based on the results I don't plan to rebuild the engine. Curious what others think. Keep in mind that at some point I'll probably swap out the 235 for a 350 SBC and 700R4 so I'm trying to avoid putting much money into the motor. Also, I am OK with cars but engine rebuilds are something I would pay someone else to do. So.... Here are the results of the dry compression test. 1 - 95 2 - 100 3 - 110 4 - 100 5 - 110 6 - 110 Wet compression test results. 1 - 115 2 - 120 3 - 120 4 - 120 5 - 130 6 - 125 Spec says that compression should be 135 Engine ran good before I started to pull it. Small amount of white smoke on startup. Spark plugs look OK. Top half of engine was rebuilt 100 miles before I started to pull the engine. Unknown miles on bottom half of engine but based on a visual inspection from my mechanic the cylinder walls looked good. I did a coolant test and it didn't show any gas escaping into the coolant. I'm feeling like I can skip the rebuild on the lower half of my engine and run it like it is. Anyone think I'll regret this choice?
