Working on a vigin 30,000 mile 283 that has been sitting for 40 years but the lifters have seized in the bore. Have soaked with "Moovit" and tried to grab and spin with visegrips. Some will spin but not lift and some still wont move at all. Any tricks to getting them out or am I just going to have to keep working at it??
In the past I've taken the clip out of top of lifter, removed the p/rod base, then taken battery terminal spreader tool [ looks like plyers with long 90 d fingers] inserted in lifter squeeze handle & wiggle lifter till it moves then up & down till it comes out!!!

Thanks for the tips and yes cam still in and engine on a stand. Can't punch the lifters out until I get them to move up enough to rotate and remove the cam. I put a bar between the cam tab and a bolt but still wouldnt turn. May have to make something up with a snap ring and slide hammer.
Can you see the bottom of the lifters, between the cam & block? Likely some corrosion on the outside of the lifters in this area. If you can clean up the lifter surface, they may move up enough to get the cam out.
I recall a tool that would fit inside the lifter but catch on the lip that holds the push rod cup in place. The tool worked with a slide hammer. But if the bottom portion of the lifter is corroded, you could score the inside of the lifter bore by taking them out the top...
Got the lifters out! Used the cam to work them up and tapped them down until I could get the cam out and the lifters loose enough to tap out the bottom. Onto the next stage...pistons/crank etc

I have seen some cool sleepers made out of 283s over the years, even really well hidden ones with Powerpac heads used but upgraded to bigger valves. Seen a few 63 on blocks fitted with 327SJ cranks and either run with 307 pistons or bored to 4 to make a 327. I had one bored to 4 to make a 302 and just fitted 041 fuelies to get accessory hole heads onto it.
