.903" vs .904" lifter?

[Talyn]

I talked with Lunati and they said that the .903" lifters would work fine in the 4.0L and they are the ones they list for the engine. Stock lifter is .904" diameter. However, now I have advice not to use a .903" lifter. According to the FSM lifter tolerance is .904"-.9045", lifter bore .9055" to .9065", and lifter to bore clearance at .001" to .0025".

So, would you advise using a .903" lifter or not?

If your bore was .9055" and the Lunati lifter .903", wouldn't the .0025" clearance be w/in spec? Have you actually measured the Lunati to be .903"(it could be .9035")?

 

[Talyn]

I just measured the lunati lifters to be .9036" to .9038", which is the same as a set of engine tech lifters and a set of compcam lifters.

So throw 'em in already.
