HELP!- Identify Rockers P4532234, 35, 36, 37 - 09/15/20 01:26 PM

I bought a set of Rockers from Mancini at the Nats a few years back.
#'s dont come up online and MP Tech line says discontinued in 2005.

Unsure of offset or intended usage.
I think I got them for Eddy Victors with .600 intake offset.

Thanks

Here are the ones MP marketed for Victor/ Stage VII.
Very short lived part numbers as Crane went out of business at the same time
They were kicked off.

I haven’t been able to find the numbers posted as of yet.
Not having access to the systems anymore, it can be an uphill battle....

I put them on a 906 head and they seem to line up pretty well. Could be Stage 6 so Id still like Catalog ID if somebody has it.

Guess they are just the 1.6 for stock valve configuration.

Sucks that even FIAT ( MP) Tech Line doesnt have the old catalogs.

Same reply, copied from the other board:
---------------------------------------------------------

I worked there for shy of 9 years, pre-Fiat and through Cerberus, the beginning of Fiat and all that.

I was provided with -some- old catalogs but not all of them.

Alot of folks aren't aware---the physical numbers on the parts usually never corresponded to a cataloged/packaged part number.

Many P numbers could be searched for until the end of time in every catalog, and won't be found.

The main tool that I would have used to ID physical numbers (and relate to a packaged/cataloged item)
would be the Performance Engineering Database, which, when I left in 2013,
nobody who was supposed to replace me could seem to figure out how to use anymore shruggy

I offered to provide training as a consultant, and oddly never heard from anyone after that.

Last I knew, the Tech Line consisted old buddy Don sitting at home in his underwear (unless he's retired by now. Guess I should check in with him, been awhile).

Those can actually be used on a bunch of different heads with no issues.
It’s not that much more offset than the ex rockers.

They seemed to line up OK on a set of 906.
I didnt do a final spacing, just a rough alignment.

Think they'd be oK?

They should work fine on stock heads.

If you bought the complete kit from Crane, it would have come with shafts, 32 .015” thick shims to go on either side of the rocker, and springs to go between the rockers.

Depending on what you use for hold downs, if you used spacers between the rockers instead of the springs....... you could also do away with the .015” shims that go on either side of the rocker.

The .290 offset Crane intake rocker has the pushrod oil feed hole set up in a very odd(and ineffective) way.
With modest solid roller spring loads they would routinely wear out intake adjuster screws.
I would connect the groove in the body to the adjuster feed hole by using a very small burr and making a small channel.
That seemed to be enough to cure it.

I only used those rockers on solid roller cams, so the mod may not be necessary with lesser spring loads.

I checked 95 to 2001 catalogs nothing,P4532693 is in most of the later ones {alu.roller rocker package offset 1.6 for stage 4 5 & 6 heads ] but is gone in 2001,maybe in 2003/4 catalogs.

PS found P4532693 as a NEW item for 1992.
