351W Rev. Rot Cam Specs

Could someone tell me the original cam specs for a '79 PCM 351W Rev. Rot?

What would be a good cam for a rebuild? I'm thinking about using GT40 or GT40P heads and a Edelbrock Performer intake.

Thanks!

the pcm book lists the lift at the cam at 0.26 , so with 1.61 rockersthe total lift is .4186.

no other specs given.

if you can pick up some 69-70 351 heads, they have comparable flow to the gt-40's unless you get the 'p' heads. here is a nice head flow comparison chart.head comparison. if you do go gt-40's, i think the explorer ones are the 'p's. make sure you won't have issues with pulling the plugs if you start playing 'head' games.

hey man. are you being redundant? used heads for cheap.

the aussie stuff looks interesting also. i have some cleveland heards i would like to modify and use someday before gas is 3 dollars a gallon.

they are just 2v's, so yes they would be considered part of the herd. i lived on lake erie in bay village for a couple years as a kid, so i'm qualified.

I really don't know I would have to call and ask if they recorded the casting numbers. I'm not going to unbolt the heads and flip it over to find out. I posted a link on skiboathelp listing a pair of DOOE with large valves on ebay. From what I have seen and read with the DOOE heads you can install larger valves and the combustion chamber is a little smaller than the GT-40's. With the 40's when you increase the valves the web between gets to thin and cracks.

Now be easy on tryan he's just a good old tennesee boy they do thinks different down there. My step-dad was from livingston and would translate for me, so tyran I understood every word.

Darn, those 351 heads just sold. His pictures he had posted however were of 302 and 289's and not the 351's, except for maybe those painted blue, but regardless, the ones he was selling were nice and worth every bit of the $600 they sold for.
BC, Do your new heads have the older 18mm, 13/16" plugs or the smaller plugs. I'm older so it's taxing my memory but when they went to the smaller plug in about '75-'76 they also went to back to the smaller 302 size valves. So if Jasper was duplicating a '79 model engine you probably have small valve heads, so you might want to invest a few extra bucks in the heads to take advantage of that cam and extra compression. And if anyone wants a used set of D0OE heads, I've got two pairs which need servicing which I'll let go right.

In case any members or guests aren't familiar with these Ford model/casting numbers, the D0OE breaks down as follows: The letter "D" represents the 1970 decade, a "C" is from the 1960's, "E" the '80's etc. The next digit is Zero, which is the actual year within that decade; D0OE heads are thus from 1970. The last two letters are the particular model/casting number.     

Jameen,
As BC noted, Comp Cams apparently will grind you a RR cam, but as for the roller spec I don't know. I came across a company called Shadbolt cams, "shadboltcams.com", who will grind you just about anything. I spoke at length on the phone to the owner, Barry, who gave me more info on cams in 1 hour than I had learned in the last 30 years, and quoted me verbatum cam specs from the last 40 years. He's going to be grinding me a slightly agressive bumpstick for a new/old RR 413 Chrysler destined for a 60's vintage Nautique- stay tuned. Anyone having problems locating a camshaft to their liking, or in need of a recommendation, should make a call to this senior gentleman and you'll take pleasure in vastly enlightening your camshaft knowledge.      

On the heads there where two different auctions one just included shipping. I would contact the seller and I would bet they could still set you up with a pair. Looked like it was a machine shop selling them and that they specialized in ford.

I talked to my guy at jasper yesterday and found out what heads are on the long block. They do a sudo flow test on all the heads they get and put back the ones that flow the best for there class II engines. They only use
D70E-AB or D8OE-DE heads with stock valve specs they do replace the seats and everything else but do not increase valve diameters or port and polish. So I would say these sould be as good or better than the GT-40's based upon the OE model disigmation.

ReidP,
The Gt 40 heads did make a great HP increase You are right,App 20-25, with the exhaust system they use.They can produce more with open exhaust. The cams however are still of the industral grind, nothing spectular, like 194 204.They use a dual pattern and 112 lobe seperation to mantain high vacumm and good idle Remember the newer boats use reduction transmissions 1.23.1 and need the low torque to turn the big dia props and pitch they use.. Torque and HP cross at 5250 on all engines and they turn their Fords app 4400- 4800 RPM. However the newer 6 and 8 point Chev offer much more They maintain there torque with the manifold style. Fuel injection is a connivence not particular an HP maker, if that were true Busch and Nextell cars would be useing them. Although they are trying to make that change. If you want I have a Dyno 2000 and if you want call me.

Reidp,
I am told that the reason,is that there are no availble cam blanks for RR roller cams. The hydraulic are cast and are plentiful. The roller blanks are a different process and Crane makes that type blank, and no longer do so as they would have to set up a new line. The call for roller RR cam are nil and stopped makeing them.
Crane shopped the country to make a experminental cam for mine to no avail and ended up with a flat tappet. However flat tappet are plentiful, just that Crane doesn't do them any longer.
