It's probably got cast builder pistons with a giant dish and poor deck height putting it in the 9:1 compression range. The two barrel is probably the biggest limit right now. I'd guess in the 250HP range with 480lb-ft of torque. Putting a decent dual plane 4 barrel intake (Performer, factory cast iron), and a decent 4 barrel Holley (750cfm vacuum) would probably gain you 20HP. If you have cast exhaust manifolds, pitch them for a cheap set of headers as well.Great forum here! Has been and will be a valuable resource for me.
I recently bought a '79 F-250 custom 4x4. I bought it to tow 5+tons of boat and trailer from N.CA to N.WA and it did the trick (despite using too low octane fuel as I later found out due to pre-ignition and dieseling problems).
The truck has a transplanted D1VE 6015 AA block, C8VE-E heads, 2bbl carb (says motorcraft on it?). I have paperwork for the rebuild and it has the following info: bored .30 over; Molly rings, balanced; Crank .010-.010; Cam 262-272;, 479-504 lift, etc.
I am a newb but a growing enthusiast when it comes to motor tech, but I was hoping somebody might give me some idea of the HP/Torque output? I know it is not a whole lot to go on, but any ideas would be appreciated
I love the old Ford Highboys and I want to fix this truck up in the near future. It still has low miles on the rebuild, it can get up and go and seems to have gobs of torque, but I would like to get it up to the 500hp range in the future.
You're going to need a lot more of everything if you want 500HP. You can build 500HP with the shortblock, but it's probably not recommended if you want it to live. Fully port the heads, a lot more cam, bigger intake and carb, etc.
