Though similar in form, the small-blocks are quite different internally. The S/S engine has a 400ci displacement (4.185 x 3.750) built by Pennsylvanian Brian Tilburg’s Balancing and Dyno Service in Montoursville. Tilburg based it on a vintage block, laid in a Callies crankshaft, Manley rods, BME 10.5:1 pistons, and Total Seal rings. GM cylinder heads hold Manley valves, hardware and springs, Jesel pushrods and rockers. A Comp cam of undisclosed specification does the jiggling. Tilburg sealed the long-block with a Moroso pan and pick-up.
For the induction system, he began with an Edelbrock casting topped by an ancient, though rule-required Rochester Q-Jet (prepped by Jim Boburka, Corapolis, PA) that juts wart-like on the nose of this otherwise high-tech palette. Fire is from familiar MSD equipment, providing a total 35 degrees timing, including a Pro Billet Front Mount
distributor working off a Jesel belt system.
Master snake charmer Herb Gebbler (Baltimore, MD) constructed the 2-1/8x12-inch primary pipes merging with 6-inch long collectors. Typical of NHRA class racers everywhere, Gary was reluctant to provide gross output of Tilburg’s combination.
The Comp bullet is the quintessential 9,000-rpm small-block. The icon features a 4.0-inch bore and a 3-inch stroke for a total of 304ci. Who of the Chevy faithful didn’t happily rev the pee out of one these? Alan Patterson (pattersonracing.com, Augusta, KS) somewhat of aChevy icon in his own right, formed the small-bore motor around a whopping 16.0:1 static 
compression ratio (BME pistons and pins, Total Seal rings, and CFE cylinder heads).
Those BME slugs traverse on Manley connecting rods and one of Sonny Bryant’s finest forged arms. At the heart of it, another Comp roller of undisclosed specification works with Jesel and Manley pieces.
The fuel/air intake is a CFE manifold matched to the much fussed-over cylinder heads. To feed the rabid Mouse, Comp Eliminator carb specialists Book Racing Enterprises (bookracing.com, Frankfort, Il) built Richard a Custom 3 Circuit 4150 Holley. Back in Baltimore, Gebbler put up some stainless exhaust extractors featuring 1 7/8-inch primaries and 6-inch collectors.
