Thank You Sean

the ones i've had apart were all full cylinder/shell type.

*squints* you shore you ain't talking 'bout some of dem FE lifters? ;D

p.s. sorry for junking up your thread. sean is an awesome dude with tremendous talent!
Not that it's any proof, because you know how parts listings are these days, but Rock Auto shows both types of solid lifters. The dumbell and full shell type. That's for a 64 Barracuda with a 273.
