’440Source.com’ rockers,

After contemplating in which car I wanted to put this engine, I ended up deciding for my 1960 Chrysler NY.
I have also installed a set of LongRam-intakes on the engine in the car, so I had to alter a couple of things on the engine before this would fit. Therefore I’ve changed the cam for a more milder hydraulic grind which works better with the longram intakes.

Cool setup! So what cam are you using? I am building a similar setup and having trouble deciding on a cam…
Hi Dave,
I used a little above stock cam in this motor. Don’t know the specs exactly as I bought it used with all the lifters in place.
If I had to guess I think the cam is in the 268 to 272 adv. duration region. Pretty tame.
I did use 1.6:1 ratio rockers to increase the cam’s lift a bit.
In the mean time I have bought a roller cam to be used in the motor, but haven’t gotten around installing it yet.
The roller has the following specs:
CompCam XR274R-10 – Mechanical Roller
Advertised Duration 274/280, Lift .564/.570
I’m not yet sure how well this cam will work with the longrams, but with 500 cubic inches on tap for streetuse only I don’t think I won’t loose much power anyway.
Good to see longrams in place. Have two pair with the carb heaters butchered-off my p.o.
Set of short rams too.
Intend to do a build-up ona 440 wit Holley propane carburetion

Hello Lee,
Propane is widely used over here aswell. It’s about 1/3 to 1/2 cheaper then regular gas here.
Short rams are cool. I’ve got 2 pairs of longrams.
At the moment the longrams are off the ’60 NY’er for the time being, and a dual carb inline intake has been installed instead. Since I’ve just installed a mechanical roller cam, I’ll be adjusting the valves a couple of times probably. Without the longrams in the way this will make the job a lot easier and faster.
