Alright, it's just that I've read that you can gain a little more low end grunt by advancing the timing.

To explain a bit better. The original timing chain in your truck is going to be stretched, guaranteed. It just happens over time with miles. Since everything having to do with an engine eventually wears out, I wouldn't try to say that a double roller timing chain will never stretch. So, double roller or not, a new timing chain will tighten up the relationship between crank and cam, causing the valves to open and close at precisely the right time, where they may have used to be a bit inaccurate with the old looser chain. So that's benefit #1 of replacing it, and that benefit would be acheived whether one used an original "morse" style chain or a double roller.

Benefit #2 is the friction reduction. There is less contact between the gear teeth and the chain with a double roller set, resulting in less friction. The contact that does exist is also more optimized by design of the chain/teeth, so it creates the least amount of drag possible. The morse chain is also significantly heavier than the double roller. Weight multiplies when rotated at speed, so as engine rpms increase, more rotating weight makes more drag, hindering quicker revs and horsepower.

In the case of removing extra load from an engine, you would see an mpg gain along with the extra power.

Very nice post spot on.

Yeah I never heard they actually had less friction but that does makes sense. Just replaced a stock one today with a double roller and there is less chain/sprocket contact and i believe its lighter, thanks bud!

then get one. i think think one out of a 98 would work or any other dodge made before 2001. maybe you could get one with the wires at the junk yard for cheap.

The only place for a speaker is in the dash though, and all the wiring is effed up. Like bad...

so install new wiring for the stereo. it so easy. you would have to add a constant power wire for any new stereo anyway or you could just buy a boom box and somehow wire it into truck power.

I've thought about the latter. But for now, it's paint and repair.

lol. you should still call up a junk yard and see what they would want. i would take a stock stereo with wiring for $10 or less. if you could also get some speakers cheap that also be good. too bad you didn't live a lot closer. i still got the stereo that came out of my 81. i also had some old speakers that would be better than nothing.

Local yards around here want $75.00 for a stock radio... I hardly bother with them for anything.

I'll likely end up just pulling the radio and whatever wiring I can find, out, and making a plastic cover plate.


That WAS a power wire, I think...


That is the radio. All the connections fell apart and nothing is labeled, so I have no idea where anything goes.

But anyway, thread-jack aside.
