400 Indy huge Issues
Hey yall, I have a 1988 400 indy Liquid. Now in previous years this sled has been insane! Would easily show you 95-100 mph. I have NEVER taken anything apart that hasnt needed so. So Im not sure if its been bored to the walls or anything. Dug her recently and put some fresh gas and plugs, got her fired up, but is bogging something crazy. Despite the problem i took it for a ride, in hope it would come out of its daze. Well, If you hold her wide open, she bogs up to 6-7 grand then takes off like a scared rabbit. for about a mile, then it over heats. I have topped up antifreeze and bled the system so its not an airlock. Put the compression tester on it and get this(mind you i think the testers bad) about 50-55 pounds each side. WTF? I thought you needed a good 90lbs to make an engine run? Head gaskets? Waterpump? Im at a loss. Still starts relatively easy and will idle, when u try to rev it, it bogs till it engages at 4 grand, then stays at a high idle almost engaging.
