You have to admit that these guys are impressive, when given some misinformation they zeroed in on the exact area where the problem was.

I don't think that would be an issue, companies stop making that small cup lifter decades ago.


running up my post count some more .

That's why I said quick and dirty. Check if the #6 cyl lifters are level when #1 is on TDC compression (#6 TDC overlap). If they are the cam is installed at split overlap (no advance or retard).

I've been bit on this before cuz some marks ain't stamped dead on & are misleading and different brands can have a different combo of heiroglyphics. Keep us updated..


Well all went back together and I got a hold of the FItech guys today and sorted out the problem I was having. A simple fix after I got a hold of them. They need more techs. Tomorrow I hope to fire it and break the cam in. Another step forward on a long term project. I'll drive it as a rat for a season then strip the body down for a repaint.

That's one of the reasons I posted. I had racked my brain and was at a stand still.

I recently put a 5.7 hemi together, never thought anything about it after doing tons of mopar engines... put the timing marks cam at 6 and crank at 12. When I was spinning it over, at 1st had a tight spot, but seemed fine. Put in the truck and it sputters and spins fast when I tried to fire it. Turns out I had the them both backwards. Lucked out and didn't bend a valve since it's interference engine.

Anyways, it happens!

Nope..... Still available.

But I think that the only difference is the ball and plunger cup size. I think plunger height and PR length are the same. I guess if you put a 68 PR in a 67 lifter the total stack height might be a little more.

66-67 = 9.375"
68-78 = 9.315"

66-67 = 9.375"
68-78 = 9.315"


And there is the answer. Thanks
