Hi everyone Im just wondering what brand / part number solid roller lifter people would recommend for a 440 big block that will see some street and some track use. I have heard that some dont have pressure fed oiling and are more for race only use and wont last long on the street. Thanks

Do you know approximately how many cc's was taken out of the 240cc port to get these figures?

Thanks, just curious as a friend has installed some of the 325cc runner procomp heads on a 458ci/440. They flow only a few cfm more than what your Edelbrocks did, but i am assuming yours are a fair amount smaller cc wise and more efficient.

With the ported edelbrock heads,do you recall how much was taken out of them and what the final intake runner volume would have been roughly?

Just wondering what peoples opinions are on these heads. A friend has the 325cc cnc ported ones that run the offset rocker fitted out with decent valves, springs, guides etc. They are a huge inlet port and he had them flowed at 356cfm at 700 lift on the inlet and 295cfm on the exhaust. Im...

Thanks for that, what brand of rockers do you run? I think his are 1.6:1, which I'm not sure if that would make things worse?

Hi everyone,a friend of mine has built a big block with victor style knockoff heads and has used harland sharp roller rockers Does anyone know if there is a valve cover that will work without modifications to the rockers,they are rubbing on the std steel covers mainly on the inlet manifold side...

This decision could also be affected by what aussie A body is it going into and the legalities of engineering it . A 383 may be legal out here for engineering purposes but a 440 may not be. This can sometimes favour a 383 or 400 being used (can always stroke it and they wouldn't know)...
