what to do?

I've got a 78 ford bronco with the 400. It has mabey only 200 horse, but I want to use it for mudding. I'm only 16, and a little tight with money, so should I be putting a new cam in for more power, or putting some locking diffs in first?

thanks.

For power, get an rv cam, dual plane 4bbl intake (off ebay for cheap) and a 650cfm carb (you can get eblebrock packages that are well matched), then you'll have plenty, and if you want get some headers and exhaust work down if you have some extra.

As far as lockers are concerned, I'd save the money and get some good tires first, and learn what you can and can't do, as this will make you a much better driver, so when you get the lockers you will be in top notch driving form, well should be anyway .

it's been my experience that a good dual plane intake and a big ole gas slurpin holley make the world of difference on the 400's... might wanna check the 335 series forum though..

If you did that, then it would be easy to get to the cam then and might as well do that then too.
If you do the came, then you need to replace the lifters, and have to take off then intake for that, and might as well get a 4v carb and intake.
After you did all that might as well do headers and duals.

I'm 16 w/ a 79 Bronco, and this is what I did on a limited budget.
First I bought tires and wheels, then a bought and installed a 6" lift.
I used it and it did extreamly well for open diffs and a stock engine.
Right now I saved up enough to do front gears and lockers(should be finished in a few days), and through this summer I'll have enough to do all the above mentioned engine work.

When I did my chain I didnt do the rest even though I had the parts.After the lifters then springs then guides then head rebuilt...Then screw it rebuild the motor..Then screw it go with a stroker..But wait why not a 460 motor instead....The list could just go on and on.....Its really what you want and how much money and Bronco down time you are looking to have....I now try to only replace the bad and hope that the Bronco gods have the same plan I do....So far its working....I tried the 600cfm and the 650cfm carbs over stock not much difference....Had headers on my old 400.. A little not much...Sounded cooler though...But I like the chain the best...Idled much better and felt like a rebuilt motor for 4 hours worth of work...Have to take the rad out though...Probably gonna have to use an impact to take off the crank pulley....

There are 2-3 mods that will give you results:

1) Headers and an aftermarket muffler/exhaust (like a Flowmaster).
2) Aftermarket timing chain and set it straight up. Factory chains were retarded, as are stock replacements.

If you have too high of miles, save your money for a rebuild. There isn't much you can do for a cam unless you plan to replace the valve springs as the stock ones won't take much of a lift that good aftermarket cams provide.

Actually you can get stock chains timed straight up, you have to get the ones for 80 or later i believe (we put one in my 80 and it is a stock replacement timed straight up.)
