WE BEGIN THE BUILD OF A BORED STROKED PONTIAC 455 TO OBTAIN 501 CID AND ABOUT 600 PONIES. THE GOAL:TO CREATE AN IDEAL “INDIAN” POWERPLANT FOR STREET, STRIP AND STREET RODDER APPLICATIONS Prior to block machining, the block exterior was smoothed and detailed. Not only will this ressurected Pontiac provide some ground-pounding thump, but it’ll [...]
WE BUILD AN LS ENGINE ON A BUDGET AND TRANSFORM THE MODERN ENGINE INTO A RETRO MOTOR THAT HARKS BACK TO THE GOOD OLD DAYS IN THE PROCESS. BASICALLY, WE’RE BUILDING A CARBURETED 327 CID LS ENGINE, WITH CUSTOM TOUCHES THAT REMIND US OF AN EARLY 1960′S SMALLBLOCK CHEVY We started with an [...]
Holley has announced their all-new, whiz-bang LS engine components catalog, chock-full of newly-released go-fast goodies for GM LS engines.
The vacuum pump and alternator setup hangs low, leaving the head area clean. Belt tension adjustment on radius tooth setups don’t require much tension at all, which removes a bit of stress from the crank. The tooth engagement alone provides a positive pulley drive. Routing the -12 plumbing from the vacuum pump to the valve [...]
Even though the drive hub system will be clamped to the crank snout with the 6-inch long center bolt to prevent the possibility of independent hub rotation, two roll pins are installed to the hub. The countersunk inside face of the ATI Super Damper was then drilled to accept these roll pins. Plumbing the vacuum [...]
The BG fuel log is adjustable for length, allowing bowl-to-bowl spacing to be set by simply slipping the male tube inside the female tube. The male tube section of the BG fuel log features three sealing O-rings. Fitting the BG fuel rail to our Dominator was a piece of cake. I installed the Race Pumps [...]
Our initial distributor offered a very neat low profile, but the large diameter of the head made installation impossible due to a lack of intake plenum clearance, so I switched out to a smaller-diameter-head MSD. The MSD Pro-Billet distributor (P/N 85501) provided the intake manifold plenum clearance that we needed. Our MSD distributor features a [...]
CARBURETOR/FUEL PLUMBING Our big-gulp carb is Holley’s Ultra Dominator (P/N 0-80673), an 1,150 cfm race carb that features billet metering blocks, three-circuit metering, mechanical secondaries and oversized sight windows for easy float adjustment. Recommended fuel pressure is 5-7.5 psi. The anodized billet metering blocks feature changeable idle feed restrictors for easier tuning of the idle [...]
We build a big, big block drag mill just for the sheer hell of it. by Mike Mavrigian photos by author Some folks love to claim that bigger is not always better. While that may be true in some cases, let’s face it…when the conversation turns to displacement, well, bigger cain’t never hurt. After all, [...]
