Built it last winter to use as my tow rig/DD when ranger is down.
Specs:
79 Ford on 85 F350 4x4 frame. 11,000 gvw.
Dana 60 front, sterling 10.25 rear 3.55 posi.
Alcoa alum wheels, 89 Cummins 12valve, 96 NV4500 5spd, NP241 transfercase. Slip yoke elim, custom made intercooler setup, 60mm turbo housing, 4" stainless exhaust, train horns. Future upgrades are a DennyT fuel pin, 3200RPM gov spring, and some bigger injectors. I also bought a PTO and hoist to make the flatbed dump but haven't had time to install yet.


yes those are 2 more 79s in the back of photo and yes they both have D60 fronts also.

Don't suppose you want a 12cm wastegated turbine housing ? The stock 21cm housing a lag monster.

Being the motor is a 89 it has a non wastegated 18cm onit now. I'm thinking of going to a 16cm.

A '79 F350 with a Cummins! That's definitely a vehicle/build that should be featured in an article for the fullsize site I'm building!

That think probably has mad torque !! What is it a Cummins 6bt ? God I'd sell my niece and nephew for a rig like that (sorry I don't have kids of my own to sell)

My pops owned one with that same orange color (don't know the yr) but I asked him about it since getting more into the Ford trucks and he said it had a 390 in it.. Man if he still had it and sold it now I would seriously buy it from him.

Yes 6bt. It hasn't been dynod but it is prob close to 500ft lbs from what I have read online based on other people with the same mods. But hopefully if I can sale some of the extra axles and stuff I got I will be able to buy some new injectors and exhaust housing for the turbo plus install my other parts I already have waiting for it and I should be around the 600ft lbs area.

NO, don't downgrade wastegates!!! your housing pressure will skyrocket.
Just upgrade right and proper..... never down-grade.

I'd do an HX 35-40 hybrid if you couldn't afford anything better, btw I hit 65psi with my old hybrid running from the cops, and cracked a head............... they aren't kidding when they say 45psi max on those.

but then I upgraded again (yes the proper word is upgrade!!!!!) to O-ringed heads, 200hp injectors, blablabla a crap ton more money, and an industrial injection 66/71 with a 3 in downpipe.............. aaahhhh much better.

Whats the difference between a HX35-40 hybrid and my H1C with a 60mm inducer housing and wheel?

the hybrid is just the HX 35 exhaust wheel, with an hx 40 inducer wheel.....

it spools as fast as a 35/35, pulls the air of a 40/40, and doesn't have the shaft snap from turbo "bark" associated with the 40/40's. the 40 wheel is just a jag bigger than the 35 inducer wheel.

Yea, but what is different between my H1C and a HX35? I know mine originally was a 50mm inducer and 18cm exhaust. now it is 60 and 18. And a HX35 is 56mm and 12. being I shouldn't downgrade the exhaust housing why is the 35-40 better? Are the rest of the internals better? Why does the 35-40 build more boost than mine and cool better?
