Lazer 2860639 Comp Nostalgia 271+ In stepping things up, we decided to utilize the same short-block, though we did have to disassemble the motor to have valve reliefs cut into the pistons for our more aggressive cam profile(s). Wondered why it did not come up to the full line at 5 quarts. Same thing goes for the heads and I have a set M-6049-C3 part number high port (not Yates) heads. While the CHI heads offered CNC combustion chambers and an impressive 320 cfm right out of the box, they were given the once over by the gang at Dr. Js. Flow Data - Flow Test done by myself on a Superflow600 at 28" valves and seats were 100% stock out of the box Manley 11878 Intake, Manley 11847 Exhaust. Not bad considering we were dealing with a static compression ratio near 10.5:1. The Boss was topped off with an original aluminum dual-plane intake, 750 Holley carb (they came with 780s originally) and a set of 1 3/4-inch Hooker headers. Boss 429 stock heads:flow specs. . We swapped out the original Comp cam and installed the stick from Cam Research Corp (www.cam Intake - 2.19 inches Some camshafts may no longer be available from the manufacturer.

The odds of you building a vintage Ford BOSS 302 engine are slim because Ford built so few and so many are already spoken for. Lots of great information. Small block Ford PRO1 20 170cc Aluminum cylinder heads feature high flowing as cast ports with profiled valve guide bosses and are bowl blended on 5-axis CNC machining centers. Every time I put a bigger carb on it, it ran faster. The oiling system upgrades were critical for our high-rpm needs. Boss 302 Mustang; Overview; Manufacturer: Ford: Production: 1969-1970 and 2012-2013: . Boss 302 is a Windsor engine; uses Windsor cam lobe profile & 1.6 Windsor rockers. Required fields are marked *. Junk ass Chevrolet stroker engines.puleeeeeze. HOLMAN and MOODY C30Z The as-cast port dimensions (170cc intake and 66cc exhaust) compared very favorably to the stock E7TE 5.0L head castings. The Race head flowed a bit over 300 CFM at .700 lift with a fair amount of turbulence hurting the flow. TRW developed these pistons and suppled Ford with them for both racing and production engines. File reflects which was used. The pistons and the compression ratio, carburetor size, carburetor jetting, the valve sizes, the rocker arm ratio, the transmission gear ratios, the rear end ratio, the wheel size, the tire size, the exhaust system Well, we hope you get the idea that choosing a camshaft is not to be taken lightly and you must understand its importance on your car's performance and meeting your expectations. For the 1968 Trans Am season, Ford took the 302 cubic inch Tunnel Port out there in search of victory. . That being said, we still have to recognize that the late-model 5.0L Windsor-based engine jump-started the modern blue-oval performance revolution. The 4V heads flow amazing numbers, and will give the aftermarket heads a run for their money. Companies like Edelbrock, AFD, Pro Comp, Trick Flow, and Cylinder Head Innovations (CHI) have all tooled up to produce aluminum heads for Cleveland applications. b. Production casting part numbers: ENGLE 2122 Ford engineers took the new 351 cylinder head and modified it to work with the Tunnel Port block. rough idle, The part number of the head was M-6049-C351, this head was cast specifically for 351 cubic inch motors, its combustion chamber volume was 62cc, as opposed to the 58cc combustion chambers of the similar heads from Australia. The 306-horse 289 cubic inch High Performance small-block V-8 in Shelby GT350s took on Corvette and the rest and managed to spank Americas sports car in SCCA competition. Ported Chapman Alum, Edelbrock 61139 Victor 15 Deg. This is a little known fact; the US-DOT allowed manufacturers to use thinner sheet metal in 1970, so the 1970 BOSSes are about 300 lbs lighter than the 69 BOSSes. Manganese Bronze valve guides are used . C302B or C3 Cylinder Heads - Don Terrill's Speed-Talk To better the already stout stock 4V Cleveland head, CHI not only improved the airflow, but also reduced what many consider to be an excessive (245cc) port volume. The BOSS 302 engine could use better cylinder heads with right-size port and valve sizing in a set of Trick Flow cylinder heads and a more compatible roller mechanical camshaft.
