Tri-Power - Rebuilding The Carburetors [S2 Ep. 5-1]
When it comes to classic hot-rod components, nothing gets people going like a multi-carb setup. And the king amount these is the Tri-power. Long admired for their stellar performance and macho attitude, the tri-power has become a hard thing to find. So why find one? Why not build your own? Today on GEARZ, Stacey walks you through the process of building your own tri-power out of old derelict parts. After that, Stacey pulls out the big Mopar guns and shows what it takes to put together a six-pack. If multi-carbs are your deal... you?re gonna love this show! Then Stacey gets down and dirty and shows you how to build some simple, ultra strong axle dollys by using some old scrap metal like the kind laying around YOUR garage. Who said gearheads aren't into recycling?
Dad's 455 Pontiac
A video of my dad starting up his .060" overbored 455 on the engine stand with open headers. Its for his 1970 Pontiac GTO.
1955 Pontiac StarChief Hardtop Bronze/Cream
A banner year for Pontiac...a new overhead valve V8 to keep up with the tech flow of 1955...the ever present dual range Hydramatic, the wrap around windshield, and interestingly a front end that seems to merge the grille area with the bumper..very trend setting for the time! The colors are fantastic..very popular...and they carried over to the inside. Notice the chrome bows in the roof, to continue the illusion of a convertible! Eventually those chrome strips on the hood would disappear, along with the iconic Chief Pontiac...but they are here now in force.

Pontiac 400 first start up
First start up of my bored out 400 from 1979 trans am. Now a 406 with comp cams extreme energy hydraulic cam and lifters, roller timing chain and roller rockers. Lightened and balanced Scat crank. Ignition upgraded to MSD HEI with Accel 8.8 mm sprial core wires. 6X-4 heads ported and port matched to ported factory dual plane intake manifold. Factory 750 CFM Quadrajet reworked by Cliff Ruggles performance.

Tri-power Rochester Model BC Chevy 235 Six
This is 3 carb set-up on a Chevy 235 inline Six. This intake is an Offenhauser for the 235. The carbs are large base Rochester BC's. The automatic choke is fed from a copper tube heat riser that extends into the Exhaust heated base. The tube exits the heated cavity to the atmosphere (does not pick up carbon from the Exhaust). Fuel line is plumbed entirely in solid brass pipe.
The engine is 1959 vintage 0.60 over with the late high compression heads. 3/4 cam with mild lope can be heard in the video. Exhaust is temporarily fabbed outside the split Fenton Exhaust manifolds...so sounds a little odd with my little digital camera. Sounds a lot better in person!
Pontiac Firebird 455 SpinTech 3" w X-pipe Mufflers thru Dumps Sound Clip
a short clip of what the new Spintech Exhaust Sytem I installed on my 1968 Firebird with 455 (462) Sounds like. Hedman Headers w 3"collectors. VERY throaty. Installed full 3" system thru Spintech X-pipe and Sportman XL mufflers and Spintech dumps just before rear axle.
1961 Pontiac Catalina tri-power convertible
Now this is the car to have!! Beautiful paint, interior and engine compartment. According to the owner, less than 20 remaining. This type car was built for racing with that 389 triple carb engine, 348 horsepower, and four speed manual transmission. Note how accessible everything was under the hood! Most amazing is that this car is unrestored. That just goes to prove that if you take really good care of a car, it can look like this 50 years later!! And you can drive it, too!
