Every one says never use the old lifters on a new cam.  I'm sure it has been done with no bad effects, but!!!!

It's a real shame about the lifters because they are like new, just broken in on the Comp Cam. I don't think I should risk using them on the new Isky cam. 

I'll try the super magnet to get the lifters out...wonder how it will be trying to get the new ones in with all the assembly lube on them?

A couple years ago I posted some information from a fella who I know very well who was involved in the development/testing of the Y-block in one of the "E" buildings on Oakwood Blvd. back in the day. He's now in his early 90's.   He explained how a fabricated trough of sort was slid in the cam tunnel to catch and remove the lifters as they were released. A tool was made that would "snare" the lifter and pivot such to allow it to be inserted along this tray, manipulated in such a way while being viewed from above and pulled up into the lifter bore perhaps with a magnet.  It's a story that lacked precise detail but the point is, cam and lifters were R & R'd in short order while the engine was still on the dyno. I have never attempted to see how this could be possible but perhaps some day I may have the opportunity to explore this. Just some food for thought.........................

Very interesting! I can visualize what this device could look like. A half round cardboard or plastic tube with a slot wide enough to fit the shaft of the lifter. I have a practice block I can play with, but the pistons are rusted in the cylinders. I'll try to get them free and start experimenting with some ideas.

Cliff, have you ever tried to use this tool set? It would be interesting if you could post pics of the individual pieces so we could do some brain-storing. Thanks, JEFF...........

I say your existing lifters are safe to use on a new cam. Way back in 1963 I built a 312 for my '48 Ford. I bought a new cam (246 deg. replacement) and new lifters from the Ford dealership. I drove the car about 400 miles when a friend offered me a new 1957 factory "Blower Cam" (B7A6250C). I installed it and new HP valve springs without changing the lifters. That cam and those lifters are still in that engine with NO problems!
Don't worry about it!

Frank;

Thanks for the advice! Here is some additional information I have learned thanks to Moonshadow and Ted. Comp Cams are NOT a good choice for Y Blocks because of the lifter bore angle. Apparently, Comp Cams grounds their cams based on a 41 degree lifter bore angle common to scrub motors. The Y Blocks use a 43 degree lifter bore angle, so in my case, the valve timing was off. I think this is what caused my issue on the dyno. Ted provided me the Isky cam card he used with Chuck's build, so with Chucks blessing, I plan on having a new cam ground with those same specs. Bad news is I will have to replace the lifters also which requires a complete tear down of the motor. Well, the coupe is not done anyway so I may as well do it now...this winter.
