Hi all.I have tried using Search to answer my question, but when I Search and get more than 1 page of results, the results freeze one Page 1 and will not allow viewing of the other pages. Anyway, to my question:
What hydraulic roller lifters for the FE are interchangeable with other motors?
My recollection from previous threads is that the FE lifters are interchangeable with the 429/460's and I have confirmed this with Crane and other mfgr's.
But what about other engines? Like the 6.9L and 7.3L Ford diesel engines or other engines? Would these lifters fit? They certainly are available thru many sources at prices much lower than the perf mfgr's. Even if they did fit, would they perform well enough in a 5500 - 6000 max rpm engine?
Or do you get what you pay for? Low bucks, low performance.
Not necessarily trying to skimp $ , just curious.
