Okay, most of you know I'm going to be changing out my cams and valve springs soon. The valve spring swap will be a major evolution and I'm going to document it step by step (photos provided by Trucky of course).

djwolf37 a friend of mine from www.customdakotas.com is going to send me his MOPAR 4.7L head and cam tool kit. He is currently building a Kenne Belle supercharged 4.7L 2002 Dakota.

This is going to be the procedure for valve swap with heads still mounted to the block.

VALVE SPRINGS DESCRIPTION
The valve springs are made from high strength chrome silicon steel.
The springs are common for intake and exhaust applications. The valve
spring seat is integral with the valve stem seal, which is a positive
type seal to control lubrication.

REMOVAL
(1) Remove the cylinder head cover (Refer to 9 -ENGINE/CYLINDER
HEAD/CYLINDER HEAD COVER(S) - REMOVAL).
(2) Using Special Tool 8516 Rocker Arm Remover, remove the rocker arms
and the hydraulic lash adjusters (Fig. 46).
(3) Remove the spark plug for the cylinder the valve spring and seal
are to be removed from.
(4) Apply shop air to the cylinder to hold the valves in place when
the spring is removed
(5) Remove the camshaft (Refer to 9 - ENGINE/CYLINDER HEAD/CAMSHAFT(S)
- REMOVAL). NOTE: All eight valve springs and seals are removed in the
same manner; this procedure only covers one valve seal and valve
spring.
(6) Using Special Tool 8387 Valve Spring Compressor, compress the
valve spring. NOTE: It may be necessary to tap the top of the valve
spring to loosen the spring retainers locks enough to be removed.
(7) Remove the two spring retainer lock halves. NOTE: the valve spring
is under tension use care when releasing the valve spring compressor.
(8) Remove the valve spring compressor.
(9) Remove the spring retainer, and the spring.
(10) Remove the valve stem seal. NOTE: The valve stem seals are common
between intake and exhaust.

INSTALLATION
(1) coat the valve stem with clean engine oil and install the valve
stem seal. Make sure the seal is fully seated and that the garter
spring at the top of the seal is intact.
(2) Install the spring and the spring retainer (Fig. 47).
(3) Using Special Tool 8387 Valve Spring Compressor, compress the
spring and install the two valve spring retainer halves.
(4) Release the valve spring compressor and make sure the two spring
retainer halves and the spring retainer are fully seated.
(5) Install the camshaft (Refer to 9 - ENGINE/CYLINDER
HEAD/CAMSHAFT(S) - INSTALLATION).
(6) Position the hydraulic lash adjusters and rocker arms (Fig. 46).
(7) Install the cylinder head cover (Refer to 9 - ENGINE/CYLINDER
HEAD/CYLINDER HEAD COVER(S) - INSTALLATION).

VALVE STEM SEALS DESCRIPTION
The valve stem seals are made of rubber and incorporate an integral
steel valve spring seat. The integral garter spring maintains
consistent lubrication control to the valve stems.

cool build. Awwweee how I want a kenne bell so bad nothing better than supercharger whine. Does ur centrifugal SC whine?

 

It does, but its due to the new gears of the drive pulley input shaft. Its nothing like the whine of a twin screw or roots though.

I'm thinking I will do this in two parts. When the 224s arrive I think I will get Trucky help me swap out the cams and once I get the kit from Jay we will get under the valve covers again to execute the spring swap.

 

when are those cams suposed to be in?

 

I should get them this week. I ordered them on March 8th, Marty shipped them from KRC April 8th. They might be here tomorrow.

 

I wouldnt be able to sleep!!!

 

So are these the same as the HO cams or a higher lift?

 

224 Blower Cams
224/224 .500 lift, 115 lsa with negative 9 degrees of overlap.

HO Cams
.472 lift intake
.429 lift exhaust
With an 18 Degree Overlap

Regular 4.7L
.443 lift on intake
.429 on the exhaust with 254 degrees of duration.
With an 18 Degree Overlap

 

so what do the springs do/increase/improve exaCTLY
