Looks like a stock cam.

Looks like a stock cam.

But with more lift. I guess it would breath better and generate a bit more cylinder pressure, especially if it were ground with a little more advance.

more lift with about the same duration means quicker valve action.
The stock cam in a 200 was most likley designed in the early sixtys.
Any aftermarket cam has to be at least 20 years newer than that.

Isky doesn't update their profiles very often.

The Mile-A-Mor has been around since the 70's???

WIth 415 lift the valve lift is higher than what I think is 331 for stock with similar duration. The valve is opening faster and is opening more. It must help some without moving the torque curver to a higher rpm range.

same duration + more lift = more torque at same RPM

Every cam company I can think of has 80% of the same profiles in thier catalog that they had when I worked at Crane. (90-94) You want a special ford grind? It will cost you more money. The latest profiles made will be solid lifter ford specific grinds due to the fact that all winston cup teams must run .875 (ford) lifters. The more modern the profile the smaller the lash most of the time. The TLF (tight lash series) typicly have a lash of about .012 and .014
The H-260-2 I bought for my 300 this year is the same part # (and profile)as the ones I reccomened to customers 15 years ago. It was called A HMV profile back then. I asked the eningeers back then how much of a .842 lifter
(off brand) made contact with the cam. I was told it is about all but the outer
.010 of a inch. With a bigger lifter base the ramp of the cam can have a faster rate of lift.
All the aftermarket cams are miles ahead of of most stock profiles.

Dur @.050 - 214/224

i would like 4.5k be top rpm
i want all low end

Then don't get that cam.
Get the one on the top of the page:
Adv dur - 268/274
Dur @.050 - 208/218
Lift -.455/.480

the 214* at .050" intake event will just start to have a little lope, and you will lose some low end.

The 208* @ .050" intake event is a better choice for what you want to do.

Junk-Falcon, what is your intended compression ratio???

That will be the final determining factor in your cam choice. I agree with Linc but you will have more low end power if you are around 9-1 compression & use a cam with a 208 degree @ .050 with a lobe center of 108-110 with the cam advanced 4 degrees as long as your cranking compression stays under 195#.

With that combo you will have plenty of low end.

Get in touch with Mike at www.fordsixparts.com & he will check with George at clay smith cams for his professional recommendation. William

Use the stock cam w/ 1.6 adj rockers and backcut the intakes. From the Falcon Handbook this will give .030 w/ the rockers and backcutting will act like opening the valve sooner as in a cam with higher lift (@ another .030 estimated), with less on the pocketbook I might add.

If your chambers are 62cc, your compression would be around 8.2:1.

I have a 200/250 head with 64cc chambers, and mine reads at 8:1.

Another option would be to use a later model 250 cam in your 200. Just a tad more lift and duration.

Here, dude, this will help.
