Thanks Dave,
I am not sure if he has restrictors, but I can make a guess and say he does. There is not a bunch of oil coming up the push rods when the valve covers are off. ( at idle )
I tried when the lifters just came out of the box to push them down and found no movement.
I have them installed and am going to try your engine running adjustment.
In the old days we would run them down til the engine started to react and just back off till the engine came back up.
This is a hard deal do get right as the owner has no idea what cam is in it and the car at 2500-3000 rpm has a little miss it seems. I am going thru the carb and see what I can do. All plugs are good, wires new, cap and rotor. It also has a Mallory optical trigger.
another question, What initial timing should I see on this big block ? It has vacuume advance and mechanical.
thanks again.
PS I run an alcohol injected SBC 436. Toilet, pretty cool stuff.
