Projects 63 fairlane build **Camshft 1-3 build starting on pg 4**

You might check out this link:http://www.howardscams.com/index.php/ford-v8/ford-v8-221-302-50l-except-ho-1962-1995 Howard makes a hydraulic version of the 289 COBRA K-code cam.This is what it sounds like:https://www.youtube.com/watch?v=3lgIfOYYADU

 

Well i will not be using this cam. I think I'm going to use one of the following: Comp cams XE274H or N+271H, N+271S or C30ZS. any thoughts on these or real world use.

thanks in advance

 

Several forums show posts from guys that are having lobe failure issues with Comp Cams,if your mind is set on only using their product pay the extra bucks for nitriding :http://www.compcams.com/nitriding/ Howard,Isky and others already have this feature without the extra cost.http://www.summitracing.com/parts/hrs-mc210041-12/overview/make/ford

 

thanks for the heads-up Jeff!! does not have to be comp cams just like those cam profiles will probably go with the Howard's have heard good this about them. anybody ever had any issues with a Howard camshaft???

 

Think I might go with this on from Howards

Something doesn't seem right with that cam....It looks to me like they got the specs mixed up in the catalog to include duration#s from one place,and lift #s from another cam.....those lift specs look crazy high for a flat tappet cam....unless they misnamed it in the listing and its a solid roller.....Usually a cam with .050" duration around 230* ends up with .510"-.520" lift.....

For a sbf anyway...

Howard's web site shows the same specs for 210542-08, I found the cam on there site first but could not get the spec to copy on to the site.

 

With that amount of lift be sure you get the matching springs and convert to screw in studs and better rocker arms than stock.

 

already have springs good to .600lift, screw in studs with roller rockers.

 

Modern cams will out perform the old factory stuff. Give Comp Cams your engine specs etc & let them spec one out for you. Youll be much happier with it.

 

already did that Have contacted Comp Cams and worked out a custom grid Solid lifter also.

Specs are

110 Lobe Sep
Dur@50 230 IN 236EX
valve lift .522in .536ex

 

I like the 108 lobe center as opposed to a 110-112 on a SBF(also sounds a little more wicked), also degreeing it 4 degrees advanced will bring in low and mid-range torque a little earlier.You might consider this also:http://www.summitracing.com/parts/lun-10350704/overview/make/ford You can order any of the cams with the 351W firing order also used on late 5.0 H.O.Fords there is an advantage in doing so,here are some good reads on why:https://www.google.com/search?newwi...3349.0j27.27.0...0.0...1c.1.17.hp.asnr3Kme0bU

 

That's true,but you'd be surprised how well an old cam from the '60's performs,when it was originally designed by an engineering group that is part of a multi-billion dollar company,for the owner's pet project,to settle a vendetta at the biggest 24hr endurance race on the planet.....

That's weird...it was supposed to have a quote with it....the one about the modern cams...

well after calling Howard's today and talking with a gentleman named john I think i have my camshaft. http://www.summitracing.com/parts/hrs-210991-08

 

That's a bit shorter on duration than I would have chosen,but I'm a bit of a caveman...lol!
With 220 duration,and that tight lobe separation,I think you may have picked a winner though.It will have decent street manners,and should make pretty explosive midrange power,and idle with a really nice,tough sounding lope to it.The lift is high enough that it should make some pretty serious torque for a small engine.
Keep us posted when you stab it in the motor!Im really anxious to see how it performs.

I would verify the lobe lift, if 543 with 1.6 @ 220 is true that's a hell of a cam.

 

I was thinking that too...almost looks like 1.7ish numbers,or a roller...The other Howard's cam had unGodly high lift for its duration....maybe they have a glitch in the catalog?I would expect a 220 dur to be right around .490"-500"ish for a flat tappet.....I have a 228* thats .512" lift...?
If its true that that spec is for a 1.7 ratio,with a 1.6 it should be right around .510",which seems about right.

 

The specs on that cam were given to me straight from a persons(john) mouth no catalog.

When i asked about the odd duration vs lift has said that it was not a error. he said that they don't make cookie cutter cams and that the Duration vs lift had to do with high ramp rates working well a sbf .874 lifter size. i don't get it but that's why i asked these questions and called a cam guy.

 

I think I found the lobe specs;



Seems to be right on, cool!

 

hey hoop where did you get these spec??? i also see lash @.022 are these spec for a solid the howard's is a hydraulic.


I'm not that SMRT when it cam to this cam math stuff i just make sure i ask a lot of question to the right people. And then ask some more.

 

guess if you look hard enough you can find the answer to anything

Q. Why should I care about the lifter diameter?
A. A flat tappet camshaft's design is based on lifter diameter. The larger the lifter diameter the faster the rate-of-lift that can be designed into the cam lobe.

Q. What does rate-of-lift mean?
A. The rate-of-lift is the amount of tappet (or valve) lift in relation to the amount of degrees of crankshaft rotation.

Q. Why do I want a fast rate-of-lift?
A. The faster the rate-of-lift, the quicker and harder the air starts to flow in the port. This is the key to a longer, fatter power curve. This is why a roller cam works so well. It has a very fast rate-of-lift.

 

I fixed it!, That was the flat tappet spec. Check again, it's from Howards website

Engle grinds Chrysler cams with the same thing in mind....the Mopar lifter diameter is huge compared to the Chevy....that Howard's cam looks like its gonna be a snarly little bugger that should surprise a few Chevys...
Hey,does
That dude out on Walker road still have that R-Model GT-350..?I never saw that car when it wasn't sideways at about 7000rpm....Man I loved that car!

John gave you some sound advice,I think you'll be a happy guy.Maybe you can post a video with sound after you "Git Er Done"!

 

I'm starting to feel the same way. I can tell you this I will be sending business there way anytime i get the chance. Very refreshing to deal with a company that you can get a person on the phone in 2 mins and then get real help and answers to your questions with out feeling belittled or that they are just pulling them from a screen like your at autozone.

+10 for Howard's so far i will let everyone know if this changes

I will post a video once the cars up and running. thank for all the great feedback on my cam choices, that what makes form like this so great.

 

Placed my order for the cam on Wednesday will keep you all updated.

 

Boogity-Boogity-Boogity!

 

any updates?
