1986 Jeep CJ7
Engine: 1997 4.3l Vortec v6 Direct multiport fuel injection (from a Chevy Blazer). Original Chevy engine had 260K miles on it and was running when taken apart. Engine was rebuilt with the cylinder bore (.060”) and crank done by Clegg’s in Provo. Engine wiring harness conversion and ECU programming completed by Novak Conversions in Logan. The engine conforms to 1997 emissions standards and contains all emissions components including OBDII system. Aluminum 4 core radiator with transmission cooler. Aftermarket cold air intake, new battery and new alternator. New in-tank fuel pump conversion by Novak Conversions.
Transmission: 4L60E Electronic Automatic that came from the same vehicle as the engine. This is a matched set. The transmission was rebuilt by Tanner Transmissions in Lehi and an upgraded shift kit was added as well as a new torque converter. Transmission to transfer case adapter from Novak Conversions.
Transfer Case: DANA 300. Original parts with single shift lever.
Axles: Front: Original DANA 30 with new disk brakes and rotors. Manual hub locks. Bearings and seals have been replaced, but no change to axle gears.
Rear: Original DANA 44 with new drums, brake shoes, wheel cylinders, and hardware. No change to axle gears- Ratio 3.54:1
Power brake booster upgrade with new master cylinder and all new braided stainless-steel brake lines and hoses. New emergency brake cable.
Drivelines: All driveline work done by Pugh’s drivelines in Lehi. Front is original, and rear is shortened with a CV joint added. The transmission/transfer case have been lowered 1” to accommodate a better driveline angle.
Exhaust: All exhaust work done by Pugh’s drivelines in Lehi. Catalytic converter has been added for emissions compliance as well as all O2 sensors.
Suspension/Lift: 3.5” overall lift. (2.5” spring lift by skyjacker springs along with 1” greaseable shackle lift). New Skyjacker gas shocks and steering stabilizer installed. Power steering upgrade added with new gear box. Tie rod assembly flipped to eliminate the need for a drop pitman arm and thereby reduce bump steer.
Wheels & Tires: 18” polished aluminum XD KMC wheels with BF Goodrich AT 275x70r18 Tires that have 7/32” tread still on them.
Body: The tub has been converted to a CJ but was originally from a ’94 YJ Wrangler. The conversion includes tailgate, defroster vents, body mounts, and fuel fill access. The tub has been professionally coated inside and underneath with Rhino lining. The paint and finish body work were done by US Street Rods in Mapleton.
Interior: New carpet, new cloth seats, new seat belts, brushed stainless-steel dash, brushed aluminum control knobs. Steering column has been rebuilt with new bushings and bearings.
Exterior: Camaro yellow paint with stainless-steel hinges, hardware and mirrors. LED upgrade on tail, side marker, and running lights.
This CJ7 has been taken apart down to the frame and meticulously rebuilt with many improvements and upgrades. All parts were sandblasted and painted with rust proof paint. The jeep originally had an inline 4-cylinder engine with a T4 manual transmission. The new complete drivetrain was pulled from a ’97 Blazer and completely rebuilt before being installed in the jeep. It is now a fuel injected automatic with power steering and power brakes. The jeep has 62K original miles on the odometer, however the newly rebuilt jeep has less than 100 miles on it and is still in the break in phase. It drives great at all speeds and performs well on the freeway. Every nut and bolt has been replaced with new grade 5 or grade 8 bolts for strength and durability. The jeep comes with a hard top, bikini top, and soft doors. Words cannot describe all the time and effort that went into this build. Below is a link to 4 YouTube videos that I created during the project. I also have thousands of photos to go along with it.
