The crane adjustable vacuum can was one of the first things I did, I have an awsome ignition. That said I don't really listen to bear he doesn't seem to get it.

I guess I need to do some cam and manifold shopping soon I think I'll do the work after the holidays.

 

Yeah, Bear just doesn't get. But he has been winning at the track since the 60's and his equipment always runs, but damn he just doesn't get it.

 

That's vary helpfull.

I've been looking at cams, does anyone know or have a source for the stock cam specs?

 

int .436
ex .480

Stock cam from my chiltons, I used to have a book that told how to build performance fords and it had the timing on it but I cannot find it.

The cam I have in mine now is a int. 204* intake 2.050 and .484 lift with 214* @.050 and .510 lift listed as a 262/272 advertised, with a 112* lobe seperation its a Performance Automotive Warehouse cheapo #10331 and in 2000 was only $50 and now listed as $70 that is cam and lifters.https://secure.pawengineparts.com/sh...art/search.cfm

When you look at the cams make sure you get one with the wider lobe separation, that will help build cylinder pressure which helps power, also 460's like the dual pattern cams for torque.

 

I used this cam in my 460. Summit SUM-K3501 - Summit® Cam and Lifter Kits - summitracing.com I thought it had too much low end grunt, so I took it out, gave it to my neighbor who put it in his bone stock 460. He said it woke his motor up, especially above 3,000 RPM, he loved it! I had that cam in when I downgraded from headers to exhaust manifolds, it ran excellent to 3500 RPM, then the motor hit a wall. The cam kit is cheap enough, it should be compatible with your existing valve springs, I have not heard anything negative about it for normal use.

 

Is there such a thing as to much low end grunt?

 

Yes, especially when you can't keep your tires from spinning below 25MPH. Off-road was even worse.

 

you have one of the best 460 guru's in the country located down in tacoma (scott johnston),who's done extensive work on making these run good ,give him a call and he'll help you in the right direction and a super guy to do business with ,heres his number 253-988-6848

 

Then you are a liar as I can prove my claims.

 

I really woke the original 460/C6 in my 84 F250 with the above mentioned modifications. The early timing chain set, dizzy recurve ($3.00 or so from Mr. Gasket, and it seemed to add 30 hp on the bottom of the power curve!), brand new stock replacement 600 cfm Holley and I added some Hooker headers to the mix. Nothing else.

I barely noticed any load attached to it after that.

I timed it to reliably start and run without detonation on 87 octane gas. The milage was HORRIBLE! But then the power and sound were intoxicating so it was real hard to keep my foot off of the floor board. (I bought 91 octane petrol occasionally and bumped the timing when I really wanted to play. Didn't help a whole lot, but noticable.)

 

The bottom end of the power curve has nothing to do with horsepower. It is all torque. Horsepower is top speed, torque is acceleration.

 

Nah, it's all inter-related mathamatically and physically. HP can be added on the lower end of the power curve.

But I did think about putting torque into my post, but decided it would be too busy of a sentence. Most people would get the point.

Bear,does your user id refer to the cartridge?

 

Ah yes, "45/70 Government; Is the only Government I trust !!"

My favorite cartridge, due to it's connection with American history and it's stunning ability to stop game in it's tracks.

 

Good old cartridge for sure, with a lot of history. I used to hunt with one myself.

 

It's all I hunt with anymore and with 405 and 500 grain lead bullets too. Six guns chambered in it, including a pistol.
