2000 454 Mag question
 
We have two 2000 454 Mags MPH (385 hp).
Do these have roller rockers?
I searched the board and did not find an answer.

Thanks in advance!

Should have rollers
 
That engine should have roller rockers...pull a valve cover and see!:eureka:

NO!
Only 52 hr on them:D :Dand no leaks.

Pantera,
You are correct and thanks.
I found a manual I thought was
200 miles north at Lake Eire with the boat.

Thanks again.

Actually, you can pull the PCV /vent hose out of the valve cover & see if they are rollers or not..... I believe they are roller rockers, but not roller lifters.

I have a 95 454 MAG EFI 385hp and it does not have roller rockers. I added them two seasons ago. I thought the later cool fuel models also did not have roller rockers, but they did have hydraulic roller lifters.

It will have roller lifters, but not roller rockers. They will be stamped non-adjustable from the factory.

I have a '99 454 magnum. It has stamped steel non-adjustable rockers.

RPM and Checkmate are right, it has a hyd. roller cam with non adjustable rocker arms, only the 500hp's[and higher] have roller rocker arms, you can add them to that motor with no problem

yeah, what those guys said -
factory style hydraulic roller lifters
factory style stamped steel bolt-down rockers (no rollers anywhere).
