Camshaft question

[Sweden Bronco]

If am change camshaft to CS1217R 1500-4000 RPM 280/290 Adv. Duration .448/.472 lift 112 Lobe.

Would my 5.0L Bronco-88 still works well ? I have stock fuel injection.

We need a bit more info. It's hard to gage from just the info provided. What cam manufacturer ? Part # ? If we have more info we can be of more help.

Ok, after seeing what Google had to say this appears to be a Federal Mogul camshaft. I cannot find any info on it other than it's a $10 camshaft and it *may* require an aftermarket chip to work. So here's the deal. I usually try to stay away from $10 camshafts. Federal Mogul is indeed a major manufacturer but this is probably NOT a cam I would buy, not without more info. Try a major cam manufacturer like Erson or Comp Cams.

The cam will be more expensive but it will be a *better* cam. You get what you pay for. A cheap cam is a CHEAP cam. Either that or buy one from Ford Motorsports.

Chances are the cam you're looking at will run fine on a carburated engine but a fuel injected engine will need either a custom chip or an aftermarket chip designed to work with the airflow changes it will introduce. Mass Air can maybe (probably ? ) handle it, Speed Density will almost surely need a chip to set the computer straight.

Well, judging by the specs you'll be "fine" and by fine I mean it MIGHT run. If you put a computer in it that's programed for that then it's fine, if not, you'll have a hard time getting your engine to stay running. As for most of the cam, I run close to the same thing only my cam is a 260-270 duration but everything else is the same. The best lobe sep you can get for your truck would be 114* and if you stear to far from that then you get into running issues. With the duration of this cam your vacuum would be little and you'll notice it most in the idling and brakes. Also, like Broncobill said, if it's a $10 cam, I would be VERRY CAUTIOS of it. Cam's are like anything else you get, you get what you pay for. Also, I believe your current motor is a "roller" motor which means you'll have to get lifters and pushrods. Oh, also, with the stock springs on your heads, don't run 1.7 rockers because they'll bottom out your springs and you'll break things.

I understand its not a point without a aftermarket chip. Anybody have any ideas what chip Im gonna need

 

[bidibronco]

Summit racing has chip you order threw them. Within a couple of hours a "tech" will call you and ask what ALL the specs are on your Bronco and they'll go from there and burn a custom chip for you. That's about your only choice I believe. I'm not sure how it would work with sweden though?

If you're looking for some more performance try a new intake and some shorty style headers that'll fit just like "stock" and have the heads polished. A cam realy insn't anything if your intake and exhaust wont feed enough. I hope that made sense?

Thanks for good answers. Perhaps its much better to forget my plans and spend my money on a swap to 351w.

Speed density fuel injection :angry: really sacks.

Yup, speed desnity can be a real bear to work with. Any increase in the airflow just throws the things for a loop. You *might* want to consider removing most of what you have & going with either an open or closed loop Holly Projection type system. You could use a basic carb intake manifold & the Projection throttle body. You could just leave it at that and have an "open loop" system where it pretty much just dumps in the fuel you set it for and that's that OR you can use the O2 sensors to get the exhaust feedback & it will then be a "closed loop" where it automatically adjusts fuel to get the exhaust ratio it wants. Both systems give you the reliability & milage of fuel injection with the simplicity of a carb. The cam you chose should work well with it since there won't be as many inputs for the computer, all the Holley cares about is maintaining the fuel pounds per hour & adjusting fuel inputs to generate the exhaust ratio.

Just a thought. Sure would be a lot cheaper & much less work.

Am I the only one who kinda likes the SD over the MAF?
