Can I do it by myself?
Yes, but having a helper is nice when hanging the tail pipe.
What tools are needed?
Cordless impact drill, 17/64 drill bit, tape measure, silver or white paint marking pen, 3M green tape, 5/16", 3/8",1/2", 9/16", 5/8", 11/16", 17mm, 19mm wrench and socket, hack saw, cut off wheel or vertical band saw, rubber mallet, vice with pipe or soft jaws and two jack stands to hold up muffler & tailpipe during mock up.
My pipes don't fit together, what should I do?
Pipes are a very tight fit so they don't leak. Check for burrs and check pipe ends for damage. Call us if you need help!
A special high-temp joint sealing compound that is resistant to corrosive exhaust heat and gas. Fuel injection systems require the elimination of all exhaust leaks for proper operation and this does it! Applies soft so it can be forced into small openings, cracks, joints and 02 Sensor bung welds. Sets like a weld. Direct heat rating of 1000° F and intermittent temperatures to 1500°F
90° Water Pump Bypass Hose, V8
Water Pump Bypass Hose with a 90° bend molded in to go with our 90° Thermostat for all 289/302/351W V8. Necessary for most Bronco II, 83-97 Ranger or 91-94 Explorer V8 Conversions.
Alternator Adapter Bracket 351W
This bracket attach the 302 alternator to the 351W heads. They retain stock 302 mounts and use the same belts and pulleys. Shown with 3160 Power Steering Adapter.
Quik Latch Billet Air Cleaner Keeper
For decades, people have been securing the air cleaner to a carburetor with a wing nut. Spinning it on and off is slow and often results in dropping it! Replace it with a specially designed mini latch that is a perfect finishing touch to custom build. Requires modification to the air cleaner to fit the latch button. Will not work on stock carb without mod. Diameter of latch: 1.23” stud: 4.125”
Stage 8 Collector Bolts (6)
Ordinary Header bolts can be a real pain to keep tight due to the expansion and contraction that headers go through. No one likes getting in there and busting their knuckles if they don’t have to. We swear by these (not at them)! They use a patented locking system that won’t come loose.
90° Thermostat Housing
Thermostat housing with a 90° outlet for your 289 302 351W Small Block Ford V8 in Early Bronco, Bronco II, 83-97 Ranger or 91-94 Explorer V8/5.0 Conversion.
Dual Exhaust TBP Header Conversion Pipes, 1966-77 Bronco
Adapter pipes to exhaust kit to complete our dual exhaust system when using Tom's Bronco Parts long tube headers.
Heatshield Products Lava Wrap
Keep the heat off your floor boards, out the interior and reduce the risk of vapor lock by reducing radiant heat near the fuel lines with Heatshield Lava Wrap. Made in the USA Lava Wrap has all the same performance enhancements as a traditional heat wrap, but with the cool carbon fiber look and long life of fiber made of crushed volcanic rock. The lava rock wrap fiber is 25% stronger than fiberglass wraps along with being asbestos free and chemical, acid, water and mold resistant. Wrapping Lava Wrap on a header and exhaust system maintains hotter exhaust gases, decreases gas density and allows the exhaust gases to flow through the system at increased velocities. Greater exhaust scavenging is produced, pulling intake gases through the cycle faster, helping to lower air-intake temperatures. This results in more horsepower and reduces radiant heat damage. Lava Wrap lowers under-hood temperatures by as much as 40%, further lowering intake air temperatures and creating even more power. Withstands continuous temperatures of 1,200°F and intermittent 2,000°F. 2" wide roll, 1/16" thick, recommended to do 1/4" overlap.
