34 35 36 37

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.

I didn’t find them in 92 or 96 catalog.

they kinda look like TA, but I’m unsure. Fit OK on quick 906 mockup

Thanks

First off, pictures would help...
I found these two on a Russki site:
P4532234 is a 1.6 ratio aluminum roller rocker rt. for b engine
P4532236 is a 1.6 ratio aluminum roller rocker lt. for b engine

The Mancini folks might be able to help. Give them a call.

Hi,

I saw the Russian site, too.
Mancini was no help.
Neither was Fiat- MP.

Hoping somebody kept some old MP Catalogs.
They dont have correct #'s for Stage 6

Thanks for the help. Here are the Pics. Hope this helps. They are kind of uniques with offset adjuster and roller.

good find on the Russian site. At least it says big block.
Generally I’ve found that exhaust rockers are the same Indy, Eddy, OEM, stage 6.
Intakes have various offset.
I suspect I’ll measure offset.

Stage 6 .450-465
Eddy Victor .650
Indy .825

strangw that these part #’s are lost or they Got superseded or discontinued as soon as produced. Fiats MP performance line said discontinued 2005 so they may in print in 2003 or 2004 catalog

I wonder if those are something that was designed for use with the MW port Chapman stage 6’s.

The offset is measured from the center of the roller to the center of the adjuster.

I have 2 sets of the .485” offset intake rockers here(part numbers P4876438 & 39) that fit the non-Chapman stage 6 MW heads(P4876818 & P5249579) and they’re def not the same as what you have there.



Maybe if someone had the instruction sheet that came with the MW Chapman stage 6’s, there might be mention of what rockers are recommended.

Crane sold a rocker set they advertised as for the stage 4,5,6, b1-bs, and Indy SR.
It had intake rockers with slightly more than the “normal” offset.
They are offset .290.

The thing is, Indy SR’s and non-MW(and non-Chapman) stage 6’s work fine with std rockers. No additional offset needed.

A little off topic, but it does help narrow down what you don’t have.

Thanks, Duane!

Sure looks like the .290 Crane. Ill do a rough measure.

Quick measure solves it.
I was unaware of .290 offset heads.
