the engine was rebuilt about 15 years ago. (block, crank, cam, pistons, rods, bearings, only)(.060) its been in a plastic bag. I took it completly apart cleaned and put back together. a 216 and 2 older 235s have been donating parts. the lifters were from the 216 1" solid and there is no tappered area. just a hole though it near the bottom. all the lifters were the same these was the best set.
thanks mike
ps. i'm gonna warm up the shop and run the drill for about 5 min this time and see what happens.
