Crane Gold Race Roller Rockers on 3400

[v6h.o.]

they bolted on the Crane studs, stock guide plates and rockers.

Yea. So far I have put Crane rockers on...

-Iron head 3.4L stock cover fits fine
-Iron head with Fiero Cover. Fits but had to file the top tip of the rocker just on the corners.
-Aluminum head 3.1L stock cover fits fine
-3400 Stock cover is not the problem needed to mod the intake manifold

So for future refrence there ya go... And I would asume these are the biggest rockers avalible for this engine so anything else will probabally fit aswell. Well actually 614 has the biggest rockers.

Ok pics are in.

Here is the intake all finished.

Notice all the plastic pushrod guides on the gasket had to be removed

What sort of gains are you looking at here?

[geoffinbc]

Well just lighter weight and roller tip. Probabally a more accurate ratio too since some say that stock rockers are not quite 1.6. But hey its all speculation.

More of just a cool factor and a look what I did kind of thing. Plus we put them on the 3.1L and why waste $400 rocker arms right?

ya i wanna know how much of a gain u saw from this. I'm planning on swapping 3400 P&P intake manifolds and some custome headers on my 3100 sfi and these may be a good idea too while im at it who much did this cost ya again?

[geoffinbc]

The only cost is the cost of the rockers.

[customandsound]

what stud did you use to install them ?

[pantera]

Hey, thats my engine and car, now who leaked my secret project j/k . Custom&sound the rockers come with new studs from crane with special 10mm x 1.50 bottom x 3/8" studs

[geoffinbc]

FINALLY HE POSTS!!! Pantera is the other half of the project.

Not my car. But half my work

[customandsound]

i went to crane and this is what i found a miss print:

Gold Race (Extruded Narrow Body) for Chevrolet V-6 & Center Bolt V-8 Valve Covers

Narrower body for use in Chevy V-6, 90° 2.8L/3.1L. Comes with special studs to convert upper section from metric to inch. Also available for 90° V-6 and small block V-8 center bolt valve covers. Needle bearing fulcrum and roller tip. 1.5 and 1.6 ratios

It is like the third one down 25750-12 or 25759-12

Here is the included note...
d For inline valve cylinder heads. Set includes special 10mm x 1.50 bottom x 3/8" x 24 top rocker arm studs (99148-12), no machining required. Check valve covers and intake manifold for clearance throughout the lift cycle.

They are just SBC narrow boy rockers with special studs.


We sure showed them. LOL "For inline valve heads" pfft

Yes Colin deserves partial credit. But when we first put the intake on it hit the rockers I was like F**K Colin. Then me and Lloyd are like "wait" Get the die grinder there is a 1/4" of intake material here

[Manitcor]

ok so the big question, was there any noticed difference?
