Add a little Amsoil.

Here are some pics of the 440 Installed.

The engine builder replaced the bent push rods, and replaced the original rockers with some expensive crane rockers. It’s running better now, or at least on 8 cylinders anyway. It still needs to gone through and have the timing set up, carb, etc. I can tell you this, the Whiplash cam does...

We broke in the cam at my cousin’s garage and noticed it didn’t sound right when we were done and let the rpms come down to an idle. So I trailered it to the guy who did the engine work and he quickly realized it was only running on 4 cylinders, and making an excessive amount of clatter under...

After talking to my stall speed torque convertor guy, I decided to go ahead with a cam/intake swap. With an automatic trans, my 440 engines current set up just wasn’t going to work without using a 3500 stall and changing my rear gears to 4.10 so the converter would lock up on the highway. And...

My rad measured in at 22" and my standard 7 blade fan 17.5" and I don't have a shroud right now but I'm planning on getting one.

Sorry, I'm running BF Goodrich Radial TA's, 255/60/15 which have a tire diameter of 27.1"

I saw an episode of engine masters last week where they tested a bunch of different fans to see which one was the best in terms of the least hp to run and although the electric fans where by far the clear all out winner saving about 32hp and 24ft/lbs over a stock fan, I want my car to still look...

Is there anyone on here that is running there Cuda or Challenger without a fan shroud? I noticed mine doesn't have one and wondered if its a big deal or not?

Hi guys, the speedometer is off on my 70 Challenger. It reads around 85mph when I'm actually going about 60mph according to my GPS. I'm just wondering if it may have the wrong gear in the 727 transmission where the speedo cable threads into it? I've been told there are different colours...

I think I'm going to leave the engine the way it is for now with the mopar 557 cam and mopar m1 intake. Try it out and see how it works before changing things on it. Previous owner said it worked amazing, and that I would be crazy to change anything on it. I will have to get a larger carb for...

If I found some 452 heads, and had some work done to them. Would they not flow better and have less compression then the current mild ported 906s?

That's great news, because I really want to run the Whiplash cam in my 70 440 but there is a warning on there website to only install them in low comp engines 8.9:1 or less... Whiplash cams are designed for the very low compression Mopar O.E.M. engines such as all the 318's, 360, 400 and all...

Does anyone know the real world compression ratio for a 1970 440 engine? From the research I've done on the topic, it looks like Chrysler rated them at 10.2:1. But I've been told enough times by multiple people that this number was not accurate, and that those CR's could be in fact off by 1...

Yah the only thing I don't like about the 557 is its power band of 3000-6800rpm.
