VINTAGE ENGINE TECH (Part 2)

THE BOMB IS BACK

cherry-bomb-glasspack4x61

Forty years after its debut, the Cherry Bomb line of mufflers is back with a vengeance, including a wide array of street and race thunder wonders. One of the new releases, and a blast from the past, is the oh-so-famous and oh-so-Friday-night-cruising tubular glasspack. The Cherry Bomb Glasspack, the original high-performance muffler, is insulated with high-temperature fiberglass to absorb high-frequency sounds. The Glasspack’s reversible, straight-through design not only allows for the classic glasspack sound, but also reduces backpressure to maximize horsepower. It’s round, linear shape creates a universal fit, making installation a breeze.

First introduced in 1968 by the Maremont Corp., this bright red 2′ long straight pipe muffler with a baffled channel lined in fiberglass produced an unmistakable, one-of-a-kind throaty sound and less backpressure for a noticeable improvement in performance. It’s timely introduction occurred at the beginning of one of the most exciting times in the development of hot rods, 1968-1971.

This is when Mopar was king with its development of the Charger, Challenger and Plymouth Roadrunner and GTX. The Chevelle and Nova were introduced along with the first generation Camaro in response to the growing success of the first generation Mustang. Relatively inexpensive to own, these cars were easy to modify and packed with power. The Cherry Bomb Glasspack became a standard bolt-on as it embodied in sound, the horsepower under the hood.

The original Glasspack had a brightly painted steel housing, a metal baffle interior channel surrounded with a layer of fiberglass insulation. Today’s Cherry Bomb Glasspack is produced from high-quality cold-rolled aluminized tubing and
features a more durable, rust-resistant powdercoat, still in its characteristic red color. Tuned to perfection in a first-class dyno facility, the Cherry Bomb Glasspack still has a throaty sound and is available for most vehicle makes and models.

DEMON 98 CARB FOR VINTAGE-ENGINE HOT RODS

demon98

This evening the Demon 98, a new, retro two barrel carburetor for vintage-engine hot rods, discharged its first air-fuel mixture into the cylinders of a 292 Y-block Ford Starliner during factory drivability tests. As this year’s first snowflakes fell on the hills of North Georgia, the 1961 Starliner took to the road with Barry Grant at the wheel and carburetor engineer Dave Wasson. Grant beamed after the road test, saying, “It needs no more development-it starts easily, it idles smoothly and responsively, and its off-idle and part-throttle performance is as good as I know. Let’s get them into the hands of our customers.” Wasson added, “Dang! I bolted them on and she fired before I got my hand off the ignition key.”

Two days earlier Wasso and Grant made their preliminary tests, starting with the original Autolite 2100 two-barrel on the Starliner. As expected, they recognized its reputation as a durable and reliable carburetor, but one that’s not known for lively performance. Then followed extensive road testing with three Stromberg 97s. “These performed well, exhibiting no obvious shortcomings, but when compared, the 98s were more responsive, especially at light, part-throttle loadings,” Grant said.

During wet-flow tests two weeks earlier, the 98 demonstrated greater airflow capacity than the 97, indicating its potential when adapted for use on more powerful engines. Also, fuel pressures differ between the two carburetors: the 98 employs conventional 6-7 psi rather than the Stromberg’s 3-4 psi. Finally, replacement carburetor parts may be a little easier to find for the Demon.

Two models of the 98 are now available: a primary and a secondary. They differ in several ways; chiefly, the secondary model has no choke mounting, idle-mixing adjustment, or power valve. Rated around 205 cfm (per unit), these three-bolt beauties are direct replacements for the Stromberg 97, adapting to most vintage engines, including the Buick Nail Head, Oldsmobile, Chrysler Hemi, Fords Y-Block, Cadillac and Pontiac.

Editor’s note: By the way, I recently viewed this setup in person and pictures simply don’t do it justice. This is the real deal and so pretty I wanted to mount it on my fireplace mantle and just stare at it. It has nostalgia written all over it, with current techno efficiency hidden inside. Very, very, very cool.

SHE’S SO FINE

348-409-head

Edelbrock has released its new Performer RPM cylinder head for the oh-so-timeless Chevy 348/409 W-series bigblocks. Bolt-on versions, P/N 60819, and bare P/N 60809 heads are both available. Like all Edelbrock Performer aluminum heads, the new manifold is designed to produce exceptional power and torque in the 1,500-6,500 rpm range. Edelbrock engineers designed the 348/409 rpm head with a 7/16″ stud and guide plate setup, requiring hardened pushrods and stud-mounted rockers. Additional features include stock intake and exhaust port locations, stock valve cover rail height and stock valve angles for simple and effective use. The castings feature a 5/8″ deck, 220cc intake port and 90cc exhaust port volumes, 2.190″ stainless intake and 1.72″ stainless exhaust valves, manganese bronze valve guides and ductile iron interlocking valve seats and Heli-Coil inserts in critical areas (including rocker stud and exhaust flange bosses).

TWO ARE BETTER THAN ONE, ESPECIALLY FOR THAT MUSCLE-CAR ERA LOOK

dual-quad-manifold

Edelbrock has released two new 348/409 dual-quad intake manifolds for the Chevy W-series. P/N 5408 is a standard port for 1958-65 348/409 applications with standard port heads. The other, P/N 5409, is a large-port version high-performance 349/409 application for factory 583 or 690
castings, or Edelbrock’s RPM 60819 heads. Both intake versions are designed to yank in the 1,500-6,500 rpm range. Both intake manifolds are designed to accept a front oil fill tube and include PCV provision. The standard port version features 2.06″ x 1.15″ port exits, while the large-port version has 2.39″ x 1.15″ exits. The dual-carb flange features 6 7/16″ centers.

YEAH, I RECOGNIZE THAT

348-409-cover

The days of tromping through swap meets in the boiling sun and mud are over for those who lust after a set of authentic Edelbrock 348/409 classic series “scalloped” valve covers. The hi-po parts maker has re-released these famous rocker covers, manufactured from high-quality sand-cast aluminum. The finned covers are now offered in either a traditional polish or in a very sweet black crinkle coating (but the fins and logo are machined for contrast). Now you can have your covers and eat ‘em, too. No more trying to salvage beat-up oldies.

FLATHEAD BIG-CHAMBER HEADS

large-chamber-flathead

Edelbrock now offers a newly-revised cylinder head for your ol’ buddy. The high-lift/large chamber head for late model 1949-1953 8BA applications features a raised roof combustion chamber that’s CNC machined from the company’s popular No. 1115 Flathead castings. This head will support high-lift cams and is ideal for reducing compression in supercharger applications, or if you just wanna be stingy and run low octane gas. The 74cc chamber size offers increased valve clearance and increased flow.

CAN’T FIND (OR AFFORD) THE ORIGINALS? BLOCK LETTERS ARE BACK

block-letter-flathead

As yet another component in the firm’s newly introduced nostalgia-targeted stuff for Ford Flatheads, Edelbrock has released a faithful reproduction of the original Edelbrock block letter logo Flathead cylinder heads, featuring the old style (and much sought-after) block-letter company logo. This new head, P/N 1126, is intended for 1938-1948 applications. It’s functionally the same as the current P/N 1125 head, but snazzed up, retro-wise, with the old lettering. All of the heads are now cast in the company’s ultra-modern aluminum foundry here in the U.S.A. using A356 aluminum.
