can I install a cam shaft in my driveway?

IM trying to figure out exactly what engine modifications I want to do to my '91. Im definitely doing TFI, 670 TA, and an Air Gap, but I was thinking about a cam. My dad told me that he had one installed in a BMW with an I6 in the 80's and it made a big impact.

Is this something I can install by myself?

This kit seems like a nice deal: http://www.jegs.com/i/Comp+Cams/249/SK10-200-4/10002/-1

thanks

you can,the rad and a/c condenser will need to come out to make room for withdrawing and installing the cam.

performer cam is cheaper and works great.

670ta is overkill on a stock block 360,as is the rpm intake. will cost you some throttle response and fuel economy.

as long as it's not a hi-lift cam it won't scrape the bottom of the car as he drives over it.

That said I still wonder why someone would wanna put in a warmed-over cam that elevates a motor's performance in ways that cannot be used without running the risk of ticking off the cops only to lose stability and control at the low end which can be important in offroad use where you may have to gently finesse your way out of a tight spot....

When the weather finally becomes decent here I plan to do a 2-to-4bbl mod on my Waggy, and that's the extent to which I am apt to go. I'm not sure I'd want a car that is champing at the bit and lurching around like a racehorse at the gate. Ridden enough horses like that, thanks.

Sorry to be a grumpy old Yankee here, but changing my attitude is too much like work for a lazy bahstid like me....

Thanks for the response. First of all Fuel Economy is not a concern. I didnt buy a V8 Wagoneer to save gas, I just want to make the most power for my money. I was looking at the Edelbrock mild performer cam, and performer intake, but I feel like EVERYBODY runs this setup. I want to try something different.

On the JEGS site the 670 is recommended for a 350-400 ci V8, while the smaller 470 is recommended for a 4,6, or 8 cylinder under 330ci. This is gonna be a street machine, so maybe I would be better off with a street avenger? However, If a TA would work just the same, I would prefer it because it is a Jeep!
I am also going for a full 3" Doug Thorley exhaust. If that matters.


I was doing a little reading about installing a cam.
-First I remove the intake and carb (doing this anyways!),
-pull out lifters and push rods,
-remove timing cover, remove timing chain (probably worn out after 130k)
-remove 3 bolts holding upper timing gear to cam
-slowly pull out cam, spinning carefully

I would definitely take this opportunity to install a new timing set, new lifters, and new rods. maybe even new valve springs. I dont know a whole lot about rebuilding motors, but im pretty sure I could do all of those things without specialty engine tools. Guess I would also drop the pan and inspect the oil pump, and replace the rear main seal. I would also do that oil mod while I had the intake out!

How is your oil pressure?
If it is is low you probably need new cam bearings, and that may be tricky with the engine in the truck.

Its great, especially running 15W40. I have never seen it drop below 40 psi after start up. It usually sits around 55psi.

What do you think about a "thumper" cam. They supposedly give the sound of an aggressive cam, without hurting the cars streetability,

I think there's a reason that the Performer Plus cam is very popular. It's a good cam.

Lunati has one that shows slightly more torque than the Performer, but it's also about $150 more, IIRC.

Sounds like it's a pretty good setup then. But, then again, there is something to be said for being different.

I'm in the planning & purchasing stage of an upper end upgrades, including an RV cam.

I asked a similiar question recently knowing cam R&R is possible by yourself, except I asked about cam bearings. Turns out it requires engine removal and bearing R&R by either a pro in his shop, or yourself with an expensive cam bearing tool, and with risk of screwing things up badly.

And the reason I was asking is because its known that cam bearing wear is a major contributor to low oil pressure, and hardest to get to for a cure. And I wouldn't want to put in a new cam on old bearings. I would think that the older the original cam is, the less desirable it would be to replace it without doing the bearings too.

It would be a shame to go through all that work only to have low oil pressure issues and be the only reason for another tear-down long before it would otherwise be necessary.

Wow thanks alot for that input. Your probably right. I should hold off on the internal engine work until I do a complete overhaul, which wont be for a while because this 360 is pretty tight. But still, 130k miles is up there for an AMC V8.

Do you think it would run good with a 670 TA, an Edelbrock air gap, and a full D.T. exhaust? I know it may be "overkill", but will it give me more power? Im getting pretty sick of the choke on the stock 2bbl.

If you do plan to rebuild the whole engine, then you'll want to go to a higher compression piston for the cam/intake/carb you want to run. The exhaust planned will be nice for that setup too. With the higher compression, you should build nice torque with the increased cylinder pressure over low compression with that setup and have strong power too.

You would have better performance with the edelbrock performer cam, intake, and 600cfm carb with the stock compression.

I definitely remember "higher compression piston" when I go to the machine shop. I have alot of reading to do before I pull my 360. Im sure the shop will know what to do when I tell them what mods I want done.

BUT I dont want to buy 2 carbs and 2 intakes. If you were gonna put a 4bbl holley on your stock 360, would you go with the 670 over the 470?

Hey that's my truck I enjoy the cam it's a pain to warm up in the morning but with performance parts there are compromises. It actually starts pulling around 1500 rpm, and since I have a manual trans its fine. With an auto you may need a different converter. It sounds really good not just at idle but all the way through the revs, I get lots of compliments on it.

As for hurting streetability it does somewhat, for instance if I let the engine get below 1500 in gear it starts loping and the truck will rock some so you have to drive a little different, it's not as bad until the ceramic clutch actually starts warming up and getting grabby . I haven't really hated it offroad either since I always have low 1st if I need to drive really slow, but most of the offloading around here is mud and hills not rock crawling, so I'm not too worried about a bunch of torque off idle.

I'm only 20 though so my idea of whats fun for a daily driver is different than a lot of others. Maybe I'll wise up when I get older but I doubt it

Not a matter of wising up, but what your back, neck, shoulders, ears, lungs, etc., can deal with anymore. Y-o-ou-u-'ll see!
