Are 440 source roller rockers any good?

I had them on my 505" 10.04 131.54mph Coronet that weighed 3800lbs for 3 years (before I sold it to a guy in Denmark) and I never ever had any problem. They kept the valve lash rock solid perfect.

What sort of spriNo pressures will you be running?

Any more feedback on the 440 Source rockers? I'm looking at putting a set on a 440 with Comp Cams XE274H-10 cam and Edelbrock 5090 heads.

The ones on my 512 in my Challenger seem pretty good. No problems here.

Thanks Plymouth67, that is good to know.

I have about 900 miles on mine and no issues. 440 with a .545 lift hydraulic flat tappet cam.

I never actually ran my Source 1.6 rockers. BUT the screws were very impressive. Back in the day I ran Isky ductiles, Crane aluminum, and some Crane ductiles in my bracket motors. The main issue was adjuster screw. Eventually just switched to the Isky screw. The Source large screws look like a very stout product.

I have heard many people say they are not good but I never ran them and never saw anyone have a problem with them. Thats about all I know about them though. Ron
