Have my stock, 1966 Plymouth Satellite, 361 (5.9L) motor half a part getting a head job done. While it's a part, was thinking of putting in a new timing chain and cam.

Mechanic says I should go with a small 4bbl cam for improved efficiency. I'm about as mechanically inclined as a 2 year old, so have no clue what so ever on what to look for.

He told me to look at http://www.summitracing.com and check things over. As far what that site calls for, for my car, it shows 3 cams, none of which are probably any kind of upgrade, are they? Here's that link, http://www.summitracing.com/search/m...t-usage/street

Anyone have a suggestion on what would be a decent SMALL upgrade? I'm going to stick with the original 2bbl carb, at least for now.

Thank you

 

Here is a list with descriptions, I like the 252H or XE250H for what your wanting. Those others look a little bit big. Try Comp Cams Camquest program and fool around with it.

Thanks for that link coronet. Looking it over.

My brother says this would work good in my car. It's one of the 3 in the list from summitracing.com.

Would that be any kind of an upgrade? What are the specs on a stock cam anyway?

Thanks

 

Don't know stock, but that cam if at .050" is accurate then locks pretty good. If the advertised duration numbers are an indication of what the cam is, then it is heavy.

This might help: http://www.hughesengines.com/TechArt...lattappets.php

 

I can get to that site but every one of the links for the parts get me a hughesengines.clients.nharmony.com could not be found. Please check the name and try again.

The ONLY one of those that looks like it is what I want is the very first one and then I can't get to the description of what ever the link should be. Might have to try a different browser.

Does "heavy" mean cool, as in good and an upgrade?

Thanks again

Edit:
Can't get to the link description in any of the 3 browsers I use!!

 

When I say heavy I mean too much. Go to Hughes Home, then Tech Articles, then Camshaft articles, then #3 Basic Camshaft...Hyd Flat. Other articles there should explain duration. When advertised at .050" gives a true indication of the camshafts potential. More duration is higher RPM, rougher idle and poor off idle breakaway with low nunerical gears. When you see advertised full duration in the 280-290's your talking about hot street closer to race cam type specs.

If you go to CompCams web site you should find their Camquest program which has tutorials on how to use it if needed, then put in your car data and useage, several cams will come up as suggestions.

 

You talking about this thing? See attachment. I saw that previously.

I have no clue what to enter in there and I'm not even seeing the WHOLE thing there and in fact went back and tried to enter something and it doesn't work. The edge of that window is some what cut off.

Like I said above also, I'm about as mechanically inclined as a 2 year old, so have no clue what so ever on what to look for.

 

If you compare the numbers at @.050 it will give you a more "apples to apples" comparison.

Your's stock was in the 206 / 209 ballpark.. I think.... Small but considering what they wanted it to do it worked well. I want to say 115LSA.. But know Im really stretching my memory.

The ones Coronet500 suggested are my pick as well... For a couple reasons. If you leave everything else as is it will work well. Be much more responsive and you will be happy with output and drive ability.

The second reason is that if you add an intake or headers down the road she will really wake up nicely ( big jump in power) and you wont need to go back into the front cover.

Those cams you picked should be in the 206/212 range but have a 110LSA which will make more peak power. Lifts are the same as yours. A 600 cfm vac secondary would be a nice complement as well.

 

Very difficult to compare different brand cams "by the numbers" because they can be measured differently, and the ramp profile is not fully "explained" by just numbers.

I would contact comp or hughes and try to get an "equivalent" cam, that is, one which performs similar to the original HP 383 in the 68--70 Road Runner / Super Bee era. These are sometimes called "cheater" cams.

Unless you have headers, good free flowing exhaust system, HP intake, don't go "too big." This is the single biggest mistake most people make. Also, in a heavy car, high rear end gear and low stall converter, too much cam will hurt bad.

 

Try starting here:

http://www.compcams.com/downloads/register.asp

 

Yep,
Did that and downloaded the program, tried to watch the tutorial but get an error saying program must've been already installed (duh) and can't enter a thing in any where there also. Just now makes the second time I've tried that thing, on 2 different computers, and get nothing. That's why I thought that thing I posted an image of would work online, and if it was the same thing?

Like I said anyway, when it comes to this stuff, I'm dumber than a box of rocks, but when it comes to computers, I can do wonders, just in case you're going to say my computers must be screwed up is why that thing isn't working. Don't take that wrong either, not attacking you or anything remotely similar.

My mechanic is supposed to be calling me some time today, so we can figure out which one I decided on. He's the one who told me to go to summitracning and explore there!

 

Here is some ramp speed for you but don't use it without header's and intake...

LOOK AT THAT LIFT...

 

I cheated and just called summitracing. The guy I talked to gave me a couple other cams to compare with that are a notch or two below the one I posted before.

Opinions on these?

Thank you

 

HUH?

Those are the two recommended above by Coronet500 in the 2nd response. You will appreciate the first one you posted above more with add ons.

 

No way?!

Told you I was dumber than a box of rocks at this stuff!

Same part, different numbers from different companies?

 

No worries. No one is critical on this board. And the first cam swap can be daunting never mind learning the terms....Then you need to negotiate the marketing bullsh@t.

Everyone has their favorite brands and the "best" grind. Dont be afraid to search the forums and find someone who has that cam in your car. Shot them a PM and ask them how they like it.

 

I know a little about cams as I used to make/machine them at Federal Mogul, but yeah, the marketing BS and just plain number of them is overwhelming.

One of the few times I wish there wasn't such a selection!!

Showed those 2 cams to my mechanic and he says those are both pretty good selections. He agreed that the first one would probably be more than what I was looking for.

Thanks for the help. Good to see people who actually help without turning it into something totally unrelated to what was originally asked. This is how a forum should work.

If these 2 http://www.summitracing.com/parts/cca-21-220-4
http://www.summitracing.com/parts/cca-21-212-4
are the same as the ones you posted 252H or XE250H, I'm ASSUMING this one is the slightly bigger of the 2, http://www.summitracing.com/parts/cca-21-220-4

Am I reading that stuff correctly?

 

You are correct, not just "bigger" but a better more modern profile. If your red blooded and WHEN you try a 4 barrel carb you'll see a bigger improvement. I say these things because any improvement to a V8 engine is like a narcotic and is addicting.

 

This cam has as much lift as my last comp cam, their 268 H
that's what i see in every lunati cam using such modern cam grinds the lift and duration ratio's are far beyond any i have seen or used, and from what iv'e learned work best with the mopar long rod motors...
