Roller Lifter Rev Kits for AMC

["Brien Tourville" <hh7x@xxxxxxxxxxx>]

Hey Bruce !!@

Is there a supplier for 'Rev Kits' for AMC ?

These mount in the valve valley area with 
springs keeping the roller lifters in place >
usually has a pair of machined bars with
spring reliefs that mount under the overhangs.

One cool thing:
ISKY used to have these *neat* Rev Caps
that mounted over the existing valve springs
and stem with a cap top the rocker would 
ride on > good for another 500 rpm.

I checked this year and didn't see them listed.

If you are using the older "non bridged" heads you WILL need to do
some machine work. This has been a problem with AMC heads for 
YEARS
and I am totally amazed no one has come out with a decent kit for
this!. Depending on what cam you are using you might need to machine
the stud boss down to get the rockers at the right height for proper
geometry. Use shorter or longer pushrods to get the geometry right and
then cut the boss so that the rocker is in the proper position on the
stud.

 The late model heads are a different story entirely. They are already
tapped for 5/16 studs but have NO pushrod guides once you remove the
OE rockers. If it's a street motor and you are using a hyd cam with
open spring pressure of NO MORE than 350 lbs you can use small 
block
ford studs and Olds 455 guide plates. You WILL have to machine the
heads slightly (especially on top of the Exh crossover). So the guide
plates will fit correctly. I have done several motors this way with no
problems. If you are running a solid cam with more than 350 open
pressure you will need to enlarge the stud mounting holes to 3/8 for
bigger studs. THEN you will have a problem finding guide plates.
 AMC roller rockers are the same as small block Ford. I have used them
interchangeably with no geometry problems. Some will argue with what 
I
have stated above. That's their prerogative. I'm just stating what HAS
worked for me. Bruce Hevner
