just a thought what would go out on the front suspension first if I put a cummins 6bt (1000 pounds fully dressed) in my 67 f100? The wheel bearings, kingpins, tires? Assuming I had air bags up front to support the weight instead of the old worn springs. Dont worry I am not going to do it I am just curious what the weak link would be since I am not very familiar with these stock twin i beams.

Thanks

With the 1000 pounder up there, it would be whatever hit first at the first pothole. All kinds of things bend with that kind of weight. Maybe you get a way with the fan into the radiator, maybe you bend an axle. Then the next time, something takes the hit and now you've got two things out of whack. 3rd time's the charm and something breaks.

I think the deal you have on the CV PI is fantastic. You can easily recover your investment if the project proves unsatisfying. This will be a runner and will be ok on gas.

Good luck with it.

Before you start though, look at this 300 and ask yourself "could this be me?"

Remember a F100 has the same frame and I beam's (axle's) and springs as an F250 so the bearings and five lug wheels are your only week links. You want big You have to move up to a F350.

 

so the bearingw will probably be the weak link in this setup then? I was figuring that would be where it was at but was unsure.I wonder if you could get a bigger bearing setup when you upgrade to disc brakes? I guess it would just be easier to get the front suspension off of a f250, I would just like to upgrade to a IFS when I install the new engine whichever one it is.

 

My opinion only with proper gearing in the rear the 4bt would be a great choice.
Some have said said no power apparantly have no experience with cummins.
I have seen many times you can pickup a complete running driving stepvan if it has a standard it will be a ford trans autos were 400 chevy. these motors powered the vans loaded pretty well and low maintence the reason they were used so much way more torque than a 4.6 triton. weight issue would not be a problem with a 4bt.
Another plus if you buy the whole bread van with the ford setup is most of these were aluminum at todays scrap prices if you are inclined to cut it up the body is worth most of the 3000 to 3500 price I have seen them going for leaving you with a cheap motor trans and accesories. the 4.6 would be a cool swap to but the ford pu's that came stock with them were no powerhouses I have a 5.4 triton can't complain about power but no better fuel economy than a 70's pu with an fe. My 2 cents only.

 

The 4BT 3.9 intercooled version is rated at 120 hp @ 2500 rpm with peak torque of 327 lb-ft @ 1700 rpm non-intercooled versions are 105hp

 

67turbo like I said my opinion only drawing from personal exp with these motors also a fan of the6.9s and 7.3s not as big on strokers. Without looking up the numbers I think you are right on the money. also cheap and easy to raise those numbers with cummins parts. what is torque on a 300 or a 4.6 at 1700 rpms.

 

I dont think the torque is as much on a 4.6 I think the 4rt is the way to go. I am going to offer the guy $1500 for the complete car if he will take it then I will take the power brakes with prop valve and use the front and rearends in my 67 f100. I will probably put the 300 6cyl back in temporarily untill I can find a good 4bt to drop in.

That is the plan what do you guys think?

 

what is it you are trying to gain with the car suspension.

 

Better ride, power rack and pinion steering, 12" disc brakes.

 

so whats everyones opinon on the 05 crown vic front suspension? Will it handle the 4bt? I beleive the weight of the 4.6L is around 500 pounds and the 4bt cummins is around 700 pounds.

Will it be ok in my f100? I have heard nothing but no from everyone I have asked, but these same people cant tell me why, only that the twin I beam is the greatest suspension ever. I cant help but think that the 05 crown vic front suspension could handle an additional 200 pounds, but I would love for someone to give me an actual reason why it wont handle the added 200 pounds besides the fact it was designed for a car.

Please help.

Thanks
Randy

 

Could you please email me the diagram of the Mark 8 wiring harness dgoins14@yahoo.com

I'm a huge fan of the 4bt but in this case, you'd be crazy not to buy the CV and swap everything over.

The 4.6 is plenty of motor for the truck, gets pretty decent gas mileage and will fit nicely.

You should check out the episode of Fast N Loud if you have any doubts. That episode is what inspired my whole Project F'nstein build (CV front end, 5.0L engine, Tremec T5 transmission).

Buy the whole car, swap everything over, decide what you want to do for a rear axle, enjoy.....

My $.02

FYI: curb weight on a 2WD F100 is right around 3500lbs. It'll be less when you swap over the CV components.

The Police Interceptor will weigh in at around 4000 lbs. Do the math.

 

That would have been the way to go at the time but Brent at Fatman frabrications set
me up with a complete IFS kit in 2006 so many of the crown vic swaps weren't widely
publicized at that time as it was such a new thing.
The rear is an 8.8 out of a town car rebuilt with a limited slip and 373:1 gearing and
2008 Bullitt Mustang rims and tires and a parallel 4 link kit with bags.
