Unless the lifter is taller, it will not help you. Fwiw - I would put it together and check it with stock pushrods.
That'll give you an idea if .030" longer will give you the proper pre-load. Imo, .030" -.040" is good.
Let's say, the stock pushrod allows for the pluger on the lifter to push in just .010". A .030" longer pushrod would give you .040" pre-load.
Hopefully, your valve tips lengths are all the same.....
My cam requires .030 longer pushrods . If I use a anti-pump up lifter then what difference would 030 make . Thanks . BooBoo
Dave . The stock pushrods would be too short . cam is small base circle needing longer push rods . Non adj valve train .
Understood, but don't assume the .030". Check it out first [like JW said too]. I meant that you could use the stock pushrod to determine how much longer you need. An adjustable one would be best, I admit [for checking].
< Wouldnt the anti-pump lifters give the wrong preload ?
Again, "anti pump-up" has nothing to do [nessesarily] with the length of the lifter. A longer or shorter effective length on the lifter would effect pre-load, just like base circle and pushrod length would [and a few other things.].
