[citation needed] The Oldsmobile wedge-shaped/quench combustion chambers/pistons are more compatible with modern low-octane/low-lead motor fuels than the Buick 'hemispherical'-shaped combustion chambers and domed pistons. Using Comp Cams Desktop Dyno software, we specd out the motor using the specs from the block and components used, which included the detailed airflow for the ported heads. With so many different options, its important to make sure you are choosing the right cams for your build. Has anyone heard of shakers in Granger Indiana??

The TA Performance option is nearly 40 lbs lighter than stock, and they claim it actually outperforms the Poston for flow. The same procedure was performed on the oil pick-up tube passage. The 350 was the small-block engine that had exactly 349.3 cubic inches and was a V8. The Wildcat 410 was the two-barrel carbureted engine, standard on the 1962-63 LeSabre. It retained the aluminum cylinder heads, intake manifold, and accessories of the 215 for a dry weight of 405lb (184kg). This will prevent attainment of the proper torque and will require replacement of the damaged part. There are probably some minor errors in the shop manuals which appear in the following specs. Later Rover versions of the aluminum block and subsequent Buick iron small-block 300s with aluminum, then iron heads, 34 (0 and 350 with iron heads) went to a four-bolt-per-cylinder pattern.[8]. Make sure you are only buying race cams if you have a race build, and visa versa for smaller cams. Post-torqueing is not specified. Here are the readings from the computer and the dyno. Use a reliable torque wrench to obtain the figures listed below. [38][39] The regular 455 produced a rated 510lbft (691Nm) of torque at 2,800 rpm, more than any other muscle car engine. (Originally, it was known to hot rodders as the nail valve because the valves had long stems and small heads which made them look like nails. Would like to do a performance engine rebuild. 16. The Buick V8 is a family of V8 engines produced by the Buick division of General Motors between 1953 and 1981. All done, the short block is complete. 28. It was only produced through 1967, being replaced by the new small block 350cuin (5.7L) in 1968. that must be adhered to in order to make it last. Modest streets cams will improve power by 10-25 hp, while high performance competition cams can net 60-75 hp on top of other mods. See onstar.com or dealer for details. In their place were a variety of GM V8s were offered, both as standard equipment and factory options. It had the same 10.5:1 compression as its Chevy counterpart. 9-spd auto w/OD Transmission. . See the window label for the features on a specific vehicle.) The block itself is incredibly solid and is easily capable of taking more than 1,000 hp without any issues. There were two different carburetor options from 1968-1976, a double-barrel carb and a four-barrel quadrajet carb. The best way to fix this is to replace the oil pump and change the cast-aluminum timing cover to something more durable. In great shape. INT/EXH .

The water pump and cam drive are also subject to problems. Rod caps, or rod bearing caps, should be torqued to 45 lb-ft for the 327 engine and 35 for the 350 engine. When bolted on, this manifold will actually increase the air flow by 5% at .300" valve lift and 2.3% at .600" valve lift over the head alone. Known variously as the Fireball and Skylark by Buick (and as Rockette, Cutlass, and Turbo-Rocket by Oldsmobile),[6] the 215 had a 4.24in (107.7mm) bore spacing, a bore and a stroke of 3.5in 2.8in (88.9mm 71.1mm), for an actual displacement of 215cuin (3.5L). Axle, 3.47 Final Drive Ratio. [10] This raised the cost of complete engines to more than that of a comparable all cast-iron engine. Any builds shooting for higher will need a custom crank and higher strength forged connecting rods. Every torque specification should be in this table, however if there is one missing, please Contact Me and I will get you the spec and add it to the table. alleycat. Jim has been building high-performance Buicks for over 20 years and is considered by many to be one of the best. The 305cuin (5.0L) was a Chevrolet V8 engine shared with Buick: The 307cuin (5.0L) was an Oldsmobile V8 engine shared with Buick:[50], The 403cuin (6.6L) was an Oldsmobile V8 engine shared with Buick:[51]. proprietary (including but not limited to intellectual property) rights.

The front seal was also replaced with a neoprene seal. The pistons are much weaker than either the crank or the rods, and pretty much any build past 400 hp will need stronger and better flowing pistons. CO2, emissi. For that reason, the more common Buick version (which looks like a traditional Nailhead V8) has emerged as more desirable to some. The Buick 350-4 SP made 315 hp and 410 lb-ft, which was just 35 hp less than its big block 400 V8 counterpart though it made 100 lb-ft less in torque. Post torqueing is not specified, Perfect Seal is. The 430 four-barrel engine was rated at 360hp (268kW) and 475lbft (644Nm) of torque. 3) engine Horsepower / Torque Curve.
