I”ll go out on a limb here. But I think that is actually backwards to what I know about lifters. Morel is actually the one that has some very high end short travel HR lifters with billet lifter...

A couple years ago took my TA out on a cold winter night, that was really damp and sound traveled from everywhere. Man it was like driving a horror movie car that was possessed!

Back when Morel was developing their HR lifter back in the early 2000s they did a spintron test to simulate 100K miles with a .650” lift cam. Now it seems like people are afraid to drive the car...

They are more like the Bullet’s and Ultradyne’s I mentioned. The magnum HR cams normally can get by with less controlled lifter bleed rates as long as the lift is less than .6”. A lifter with a...

The more expensive HR lifters supposedly have more precise machining to control the bleed rates. Supposedly :)

Some throw an extra shim in them to limit the travel, over course they have to...

Most problems on this have arose from engines that use HR cams to get a lot more power. Pick a small mild profile, .5” ish lift, with a cam intensity of 54* or more from .006” to .050”, don’t use...

FWIW…If the engine operated much above 1200 RPM cruising in OD I doubt you could see lubrication issues with the cam. Most continuous duty industrial engines usually operate at around 1760 RPM...

Your builder did good. That is an extra level of detail that is not done often.

I did a cam for a friends 389 and went with Crower camsavers in the similar time frame as your engine. Couldn’t buy...

I really doubt the 4/7 swap will add any power on a small street cam, the 4/7 swap will sound a little different. Howard’s retrofit HR cams use a stock distributer gear, which is nice. I think they...
