This is the typical 204/214 with .484/.510 lift but on 112 degree centers rather than the 114 commonly found. Can somebody run a program for me with 400, Performer, 600 Holley, stock exhaust?
Thanx,
R.

 

Those are the specs of the Edelbrock Performer cam #2172.

I haven't seen those duration/lift specs with a 114-degree lobe separation.

 

On the one hand, embarrassing!
On the other hand, one trip to the Edelbrock website gave me a torque curve for my combination.
This cam is also sold as Speed Pro CS1085R.

I have also seen it sold by Summit or PAW with I'm almost positive a 114 degree LSA.

PS: I usually do more research than that!

 

I have seen that gragh and was not very impressed. be nice if it had some more engine info.
what happened to low rpm torque?

 

What is a good Crane cam? Optimum would be low end torque, but maintain driveability, and highway use.

I found this one, is it possible to use a 351C cam?

"Buy a cam, get the lifters free!

Ford: 351C, 272/272 advertised duration, hydraulic, cam and lifter kit

This Crane Energizer cam and lifter kit provides good mid-range torque and horsepower, and better throttle response at a price anyone can afford. It's computer developed for non-emissions controlled vehicles with tighter lobe separations and single patterns for a fair idle quality. It includes a camshaft, lifters and assembly lube."

This one seems to be the best for a 4V intake, 625 CFM demon carb

"PowerMax cams for balanced intake and exhaust flow.

Ford: 351C/M and 400M, 260/276 advertised duration, hydraulic, PowerMax series, cam and lifter kit (See Product Guide)

This Crane PowerMax camshaft and lifter kit features a dual pattern for balanced intake and exhaust flow. The special profile produces maximum low, mid, and upper rpm power. It's designed to maximize the effects of nitrous oxide, supercharger, and turbocharger systems. This kit includes the camshaft, lifters, assembly lube, and a rocker arm pedestal shim kit."

I don't want too lopey, but still want decent power.

 

A 400 that's stock other than the components you listed (including the 2172 cam) dynosims as follows

HP
119 @ 2000
152 @ 2500
188 @ 3000
211 @ 3500
218 @ 4000
211 @ 4500

330 @ 3000
317 @ 3500
286 @ 4000
246 @ 4500
195 @ 5000

Changing over to small-tube headers, along with minor porting and port matching, upped the numbers to...

Max HP - 304 @ 4500
Max Torque - 389 @ 2500

What kind of MPG would this combo make?

 

Matt, all of those Crane cams you listed are too big for good low end torque and fuel economy. 351C cams are the same as 351M/400 cams.

The Edelbrock #2172 at 282/292 is also way WAY too big for fuel economy etc...

Try the Comp cams 255DEH at 255/265

I am using a custom 260/268HR cam.

 

I have a 77 Ford F-150 with stock 2V manifold and Motorcraft carb. I installed 268 series Comp cam and headers on stock heads. I don't know what my horse power is but I can pull a large gooseneck Hillboro with a car on it without too much trouble. Empty (without the trailer) on the highway I get about 12 mpg... I got up to 15 once but I think the wind was behind me all the way. I have been very happy with the power, and the fuel mileage is good for a 400 in a truck.

 

I get 12-14 mpg out of an old stock sick 400 with a death rattle in a 78F250.

 

Yes, but do you drive it 95 mph with 4.10 gears at 6000 to 7500 ft above sea level? Almost all of my trips cross the continental divide one way or another.... The joy of living in Wyoming. I'm thinking about giving the Edelbrock/4Barrel a try. That might kick it up a bit.

 

I have a new Crane cam/lifter kit waiting for the day I do another rebuild. It's the 260/276 version (.493/.502 lift). I did quite a bit of comparing, and this cam is really close to a stock 351CJ cam (270/290, 481/490 lift). It is a bit hotter than the stock Cleveland 4V cam (268/280, 420/450 lift). I trust the Ford engineers to have developed engine components that work well with thier designs, that's why I wanted to stay close to a stock performance cam. They would have designed them to work at street levels, so I would think this cam in either a Cleveland or 400 would have good low end. And these were probably engineered to drop the RPMs of the 4V heads for street manners, so grinds in this area I would think would be excellent for a replacement cam with 2V heads.

I had GT40man run me a desktop dyno on a 351C with this cam, bored .030, 9.0:1 pistons, dual plane w/Edel. 600 carb, and Sanderson FC3 headers, and he came up with 338hp @ 5500, 380 ft/lbs @ 4000. Not too shabby for a Bronco that would primarily see mud, and not rocks. Wonder how a similar 400 would come out?

 

I have a similar setup... heres what I got

*351m-30 over
*Crane cam-216/224. @050k lift 280/290 max lift 510/536 w/110* lobe seperation
*performer 400 intake
*performer 750 carb w/ calibration kit
*heads- 3 angle v-job, shaved .030 w/performance double v-springs, and cleaned up exhaust ports
*Hedman Long tube headers
*MSD 6AL ignition

I have no clue what kind of power im making, but it pulls hard all the way up to 5500 RPM.. I have great bottom too but I Didnt untill I put a 2800 stall in w/a shift kit

Ive did the math and I get almost 10 mpg, and thats not opening it up any.. Running it hard I get around 7-8

But I dont use my truck as a daily driver either, I used to till I got another vechical, I just get it out on pretty days and only drive it about 5 times a month

 

That high stall torque converter allows the engine rpms to get up into the power band for better acceleration. Unfortunately it slips a lot under cruise so it needs tranny coolers and gas mileage will suck like you noticed.

The new cars use lockup converters to solve some of those problems. With a lockup you can afford to go to a higher stall speed to get some of that performance that some of those new vehicles have.

Unfortunately Engineering is an "art" of compromise, -give a little here, take a little there...

Wyoming- get rid of those 4:10 gears man.

Torque1st, the Edelbrock 2172 is very comparable to your favorite cam. It is not way too big.
