390 Turned 445 Stroked Mudder Project
Hey guys! This is an amazingly great forum! This is my first post, but I've checked out a good deal of the threads for a while now. Hopefully, this won’t come out too badly.
I suppose it would be a good idea to tell you about the situation. I’m a Ford guy. I’ve only ever owned fords, and rarely driven anything else. I’ve had 2 – ’77 F-250s, 1 2wd, the other a Factory Highboy 4x4 – a ’84, and ’90 Bronco II (lifted 7” on 33’s), as well as a 2001 Ford Escort ZX2, And my recent purchase of a 2008 Ford F-150 FX4 super cab. Blue Oval! Next step is a Ford Racing Tattoo… But enough of that. I’m surrounded by the Bowtie boys, and the dodge guys. I need a hand gathering info, and recommended parts for a (budget) blue oval powered decimator. Just want to shut them up.
Application: The ’77 f-250 Highboy, my Mud Toy. Factory lift(4”?), 3” body lift, divorced transfer case, np435 top loader, Though I believe it may have come with a 360? The original owner... Put it this way, He knew the truck worked, and didn’t care about anything else. D60 rear, High pinion 44 front. Standard cab long bed. I am currently running 35x15x16.5’s, though I would LOVE to switch to maybe a 13/13.5 wide, and change rim sizes so I have better beads until bead-locks are acquired.
Future Plans: Dedicated Mudder – Rockwell’s, 44’s, and new 10” total of lift. For now though, street able for in-town jaunts for future work on the truck. Or I may just keep it as is, though with a Hp D60 steering front.
Target/Desired Outcome: At least 400 HP/TQ, naturally aspirated, and exceedingly reliable. Any more than that is welcome! But I’m searching for the minimum 400 of both, if possible.
Constraints: Not looking to buy a new block (have 2 to work with), And I Don’t want to spend more than $5000 after a stroker kit (which I will explain). If need be, so be it though.
My experience (if it helps): I’ve done a few engine swaps for/with friends, changed the heads on a 390, done a few trans/t-case swaps, few bolt on mods here and there, But that’s about it.
References: If it helps, I’ve been closely following Jef Perkin’s build, and a build Carcraft has done.

What I have: (I am checking, and writing down the block numbers tonight when I get home)
390 block 2v 4bbl from a 68 Galaxy
75,000 original miles
10,000 miles off a poor rebuild (looks and runs as if original 100,000 miles)
Everything else is stock minus a cheapo-msd rip-off distributor/coil
Everything else is pretty much going to go.
The Plan:
I wanted to go with the Prison break 445 Stroker kit from Survival motorsports, which requires going .030 over. I Wanted to make the basis of my build. After that is where things get a bit fuzzy for me.
From my research, I would like to go with: (from top town)
Carb: Holley/Edbrk. 750 double pump, or truck avenger (due to odd angles when wheeling)
Intake: Edelbrock Performer RPM
Rockers: Depends on the cam type, right? If so, No Clue.
Rocker-shaft end stands: Should i be grabbing those for support?
Heads: Edelbrock, assembled, changing springs to match cam specs
Lifters: Probably go with the Survival lifters, depending on the cam
Pushrods: Not a clue
Camshaft: Need help with this. Would love a nice low lope, aggressive and mean. Need a cam that’s got potential for HP and TQ, in an operating range that would suit what the motor will run with that stroker kit, which I also don’t know.
Ignition: need some input here.
Most of the lower end stuff comes with the kit.
Oilpan: I want to go to at least a 7qt rear, or possibly dual sump? It’s for mudding, and will see odd angles, which direction should I head? Not to mention the windage tray.
Oil pump: Probably a pump to match the pan?
Headers I have, though the make/type is unknown. They are rusting through in a spot or two, and will soon need to be replaced as well. Probably go with the super stock header plug wires so they wont melt. Full Fel-pro gaskets are in order.
Machining:
I will more than likely have everything ported/polished to match.
What should I look for as far as deck height, piston deck, and squish go? Or will I need the parts to figure out the stack first? Sorry, this is way above me at my level.
What kind of machining, porting/polishing do I need? As well as oiling modifications to my otherwise stock block?
Accessories:
As it stands, the motor/wiring harness are set up for Alternator (which I may as well replace), and power steering (which the whole system will be replaced).
Also, in relation to the ignition system – I was thinking of going with a new wiring harness from Painless Performance. This would increase the energy going to the coil/distributor increasing spark, therefore horse power, correct? Seems like a very good investment. Though my wallet won't feel too good
Is there anything I overlooked?
Thank you for taking the time to read this, and I value any and all input. Questions will be answered as fully as possible, and as quickly as I can, so please don’t hesitate to ask! And please correct me if I am wrong!

Several years ago we did quite a good trip of USA, and on our trip we got to meet Mike and Christine Frade. We didn't stay long with them, but in that relatively short time we both gained a great...
