[FONT="]There seems to be some talk about the OEM Engines, and transmissions installed in the Deuce.[/FONT]
[FONT="]I haven’t read anything about people doing any conversions yet so I thought I would just ask. [/FONT]
[FONT="] [/FONT]
[FONT="]Hey!!! Any of you doing any great conversions??? [/FONT]
[FONT="]I have seen the Bob Jobs, the disk brakes, and paint; then there is wheels, and tires, and I think all that is awesome; I was just wondering the power to fuel ratio.[/FONT]
[FONT="] [/FONT]
[FONT="]I came across this web page, and I Like the Horsepower, the Torque, and the Fuel Mileage.[/FONT]
[FONT="]The Information here states that it is too much power for any on road use. Then again, he isn’t driving a Heavy old Deuce![/FONT]

[FONT="]1966 Ford Bronco - Diesel Power Magazine [/FONT]
[FONT="]Once in a while, we here at Diesel Power run across something that just makes sense. When we saw Chaz Lightner's '66 Bronco, that feeling hit us. We knew the 4BT Cummins that powered the Ford had more than enough torque to propel the beast on boulders and trails yet still achieve excellent fuel economy. The fact that the swap was cleanly done-with excellent ideas and execution-was simply icing on the cake.[/FONT]
[FONT="]The idea behind this swap first started after the wicked-quick throttle response on the 520hp, 408-cid Ford V-8 that was in Chaz's Bronco led to a spin after trying to pull into traffic. He wanted something to match the torque of the 408 while being a little less temperamental. He wasn't so crazy about the 7 mpg he was averaging either, so the idea of the 4BT swap was born. Mounting of the engine itself required minor notching of the frame (for turbo clearance) but not much else in the way of custom fabrication. An NV4500 transmission was sourced and mounted behind the Cummins with little trouble.[/FONT]
[FONT="]We get questions about the 4BT from time to time, so let's talk about the engine. A call to Turbo Auto Diesel and a talk with Ken Diaz convinced Chaz that a 400hp four-cylinder would not be a problem, and Ken delivered. The Cummins in Chaz's Bronco is one of the first 4BTs we've seen that has been highly modified, so we made sure to dig as deep as we could on the details.[/FONT]
[FONT="]For starters, the engine was rebuilt, balanced, and blueprinted to ensure vibration-free operation by Beck Racing Engines in Phoenix. The head received the usual high-horsepower, 12-valve treatment and was fire-ringed and machined for 14mm ARP studs to handle some serious boost pressure. A 12-valve lift pump was used, and a four-cylinder P7100 pump built by Turbo Auto Diesel was used as an injection pump along with marine injectors. Vortech helped Chaz design an air-to water intercooler (complete with a small radiator to recirculate and cool the water for the intercooler), and his good friend Ray Bong helped test-fit the engine 17 or 18 times in the Bronco's chassis until they got it right. As far as turbos, there have been many-the first providing an outrageous 453 hp and 712 lb-ft of torque at the wheels and 88 psi of boost pressure. The engine, however, proved almost undriveable with this turbo, not making full boost until 3,000 rpm and defueling at 4,200 rpm, only leaving about 1,000 rpm of useful powerband. Eventually, a compromise was reached, and the engine was detuned to about 350 hp while remaining torquey, driveable, and fuel efficient.[/FONT]
[FONT="]Even though Chaz has more than 400 hp (crank) on tap, gets 25-28 mpg, and can even run on biodiesel or vegetable oil, his '66 Bronco has even more mods in store for it. Right now, he's switching over to a 4R100 automatic transmission with a custom-built Sun Coast torque converter designed to always keep the engine under boost. He's also looking at adding A/C to keep him as cool as his custom ride. Now that Chaz has taken the steps to create an awesome 4BT swap (he took First Place for best engine swap at the DHRA Vegas Nationals), we hope to see more four-cylinder swaps out there. Almost 30 mpg and 400-plus horsepower in these times of high fuel prices sounds like a good idea to us.[/FONT]
