390 specs
Hey guys. I asked a question about the 390 in some other thread and they yelled at me and redirected me here.
Anyway, I have a 1973 Ford f-350 super camper special that I was interested in gaining a little more hp/tq. I have so far ordered a holley 600cfm carb and a new edelbrock dual plane manifold. I bought this truck from my dad which he semi restored and the truck is in nice condition. Can anyone tell me the Cam profile type of these truck engines? Am I right to assume they probably somewhat follow the cam specs of a rv cam since they are made for pulling?
And mainly, I want to get "better heads" what would you experts recommend for this pretty much 'stock' motor?
And since i am not that mechanically inclined (yet/learning) can someone clearly explain the MSD ignitions role, and how it helps with power?
Thanks guys, sorry for the lengthy questionnaire...

Welcome aboard! I'd like to apologize in advance: If it seems like I'm yelling, it's because I don't see so good. LOL
I don't know a whole lot about cam profiles. Someone else will have to fill in there. I can tell you that the stock grind for a truck is pretty mild. The typical truck engine also has a lower compression ratio than a comparable car engine.
If you plan on working your truck like...well, like a truck, you probably already have the better heads. A little port matching and clean up may be all the benefit you'll have use for.
The 600 CFM 4V carb is perfect for these engines.
I think just about any electronic ignition system will produce a hotter, more reliable spark. Never spent the big bucks for aftermarket stuff. Stock systems handle my current needs.
Hope this helps, Mike

Do you guys happen to know what kinda hp increase i might see on this stock application as well with just the intake manifold and carburetor add? I think it's rated at 201hp/376tq as is standard...any educated guess would be appreciated. By the way... I'm not looking to make this thing some badass roadster... I just want nice reliable power compared to a modern truck and good torque to pull whatever. I was think 300hp/400tq would be just fine.
I know the compression ratio is 8.6.1. Probably can't get away with anymore than that running 87 octane right?
If anyone can reply on easy top end builds that would make this goal attainable... I would be very grateful.
By the way.. this forum rocks.. I've been reading peoples post and replys for about 2 hours now... FORD geniuses....

What ever you can find that fits and you can afford. You don't have a lot of choices in an F350. Keep in mind though, that headers are a must, whether you do any other mods or not. The stock manifolds just plain suck. Big time. The heads aren't a bottle neck to power on FE's, the manifolds are.

Not with the cam I listed. The stock springs are good to at least .500 lift. Ditto for the rockers. I've used both with a .516 & .523 lift and one cam was a 272 degree duration (advertised not the @.050 lift) and the other was a 296* duration. Both hydraulics.

The Comp 268H is a 268* duration and .494 lift. Smaller than both i used. If the springs on the heads now are old, it would be a good idea to install new ones after the new cam is broken in.

If you decide to get a new distributor, consider our custom curved Duraspark Distributor built with our new Full Length Oil Impregnated Bronze Bushing. The full length bushing improves timing stability and spark scatter. If stock appearance is not an issue, take a look at our one piece D.U.I. Distributor. Whether you choose the Duraspark or the D.U.I., we curve each on a distributor machine based on your engine combination. Please see them at:
http://www.performancedistributors.com/forddistributor.htm

Also, there is now an excellent installation article on the D.U.I. Distributor on the Ford-Trucks.com site at:
