How hard to install a Retro Roller Cam?
 

Mark IV stroked to 496
OK, this will be my first Roller Cam install:D . I have always held off because of the horror stories I have read on this forum.:(

Big concerns are
Cam Button or what ever else is needed.
The block has the three holes for a retainer plate?
How to get the correct clearance?
Can stock timing cover be used?

Distributor gear need changed?
Timing Gears need changed?
I know push rod length will change.
I know springs probably will need changed.

I was going to contract him as soon as I find out how hard this is to do.
Probably like installing my first distributer 30 years ago, once you figure it out, it is easy:drink:

NOT A VERY HARD JOB IF ITS NOT MY BOAT. LONG STORY SHORT I HAD TO GRIND ALL MY MANIFOLD BOLTS OFF JUST TO GET TO THE HEADS.
JUST DID THIS OVER THE SUMMER ON A 1991 MKIV
I WAS ABLE TO RE-USE THE TIMING COVER
I PICKED UP THE CAM PLATE AT A LOCAL CHEVY DEALER $8.00 I USED A ZZ502/502 CAM
COMP CAM RETRO LIFTERS 854-16 406.00
PUSH RODS 35.00
ROLLER ROCKERS 13744-16 1.7 188.40
TIMING GEAR I ORDERED FROM JEGGS # 220 9-3149 119.99

YOU WILL NEED TO GET NEW VALVE COVERS
ALSO CHECK VALVE PISTON CLEARANCE. I HAD SOME VALVE SLAP. WHICH ENDED UP IN NEW PISTONS AND MORE HP:evilb:

I did my first roller install a couple years ago on my 525SC. It was a retrofit for a Gen V. It was really no big deal. Just need to have the right parts and follow the directions. Timing set is different with a bearing incorporated on the upper gear. I did not use any precision measuring to set the cam end play. Just made sure it had only a very slight amount. you use the stock timing cover.
