Yup, another 318 thread

Only 222 @ 50 and when combined with the tight 106 gives good cylinder pressure for the rpm range of the cam.
Most cams good to 6000 rpms will be to big.
This one gives up nothing..........................................
It will sound great and run even better.

T67, thank you! When going through cams, most are made for the bigger inch motors, and most don't understand the need for a tight lobe cam in a smaller engine, I have been suggesting tight lobes for a long time, even 104* on that cam would be great in a 273, sound like stink, and go like nuts. I ordered a cam from ISKY, custom grind for my truck, 228/228 .050, 440 lift, 106* C line. While it is 390 cubes, a truck needs that low end "hit" even more.

Hind end kissing over, I just don't feel so alone now!

On another pondering point off the subject, sorta, say, for example 1965, they had two 318's for the trucks. One, had 8.25-1 compression, and the heavy service 318, with 7.50-1. the Standard had a .380 lift cam, and the HD had a .381 lift cam. You couldn't hear the standard 318 idle with no muffler, and the HD 318 had a nice lump bump lump bump...... The lobes on the HD 318 were 6* closer together, same lift, 2* more duration. The HD 318 also made more torque, and HP, lower in the power band, even though the 3/4 of a point different compression. Power at an idle, even though the HD had a pretty nice lope, was greater too.

Not really relevant, just something Ma Mopar knew about making useable power a long time ago. only drawback, and why the HD 318 was only used in bigger trucks, unless ordered? The tighter lobes get worse MPG's.... Not much, but they do.

Sorry for the thread hijack. :)
