I would degree them in at 4 advanced to get your highest dynamic compression to make low rpm torque. He added some small divots with an awl, where the seal goes, to give it some teeth to help hold the seal from turning. 29.

By 1975 its horsepower was down to 150. Pre-tightening is done by going around the bolt sequence three times, gradually increasing the torque on each round. [33] Most parts except the pistons interchange with the 430 and 455. Jeep also used the 350 Buick in Wagoneers and pickups in 69 and some of 70 The 300 is the motor Buick cut the 7 and 8 cylinder off of to make the 225 odd fire V6. Long-tube headers are a great upgrade for the Buick 350 because they replace the incredibly restrictive and heavy cast-iron exhaust manifold. [10] The engine had an abnormally high scrap ratio due to hidden block-casting porosity problems,[10] which caused serious oil leaks. Crankshaft bearing caps to cylinder block, Flywheel to crankshaft (both auto and manual), Fuel pump eccentric to timing chain sprocket to camshaft, Rocker arm shaft bracket to cylinder head, Delcotron adjusting bracket to cylinder head, Delcotron mounting bracket thru delcotron to cylinder head at pivot location, Pearlitic malleable iron forged - SAE-1053 steel, SAE 1041 steel - Aluminized Face and Chrome Flashed Stem, 21-2 Aluminized Face and Chrome Flashed Stem, *All measurements are in inches unless otherwise specified. 144,000 miles. Skip to content. site (including ProfessCars and automobile-catalog.com) are protected under applicable copyrights, trademarks and other The Buick 350 also shares an integrated aluminum timing cover, which incorporates the oil pump mechanisms, leaving the oil filter exposed to oncoming air for added cooling. . More 300/340 specs here Buick 300 - 340 - 350 to 1970 Buick 350 from 1970 Buick 400 - 430, 455 In the mid-1970s Buick's 400/430/455 big blocks became unable to meet fuel economy/emission requirements and were phased out, with the Buick 350 remaining as a factory option until 1980. His work has been featured in Car Craft, Hot Rod, Rod & Custom, Truckin, Mopar Muscle, and many more. They had a pretty hot 87 Turbo T. Honestly, any one with modest engine building skills can build a proper Buick engine, they just need to be willing to build it to your specs. When massaging cast iron, use a fine-tooth bit, coarse bits will jump around, causing more damage than good. The only thing that wont need upgrading at that point at really any point is the block, which is rock solid through over 1,000 hp. It retained the aluminum cylinder heads, intake manifold, and accessories of the 215 for a dry weight of 405lb (184kg). of torque at 4000 RPMs. [10], The 215's very high power-to-weight ratio made it immediately interesting for automobile and boat racing. Conversely, getting massive cams on a 350-hp build is also a recipe for disappointment and problems. Daily, PowerNation In 1966, the 300's stroke was increased to 3.85in (97.8mm) to create the 340 (340cuin (5.6L)) as a replacement for the four-barrel-carbureted 300. In 1965 the 300 shows 10 bolts and increases the torque to 70-75. 5.3L EcoTec3 V8 engine, 355 hp [265 kW] @ 5600 rpm 383 lb-ft of torque [518 Nm] @ 4100 rpm Paired with a 10-speed automatic transmission May require additional optional equipment; Capless fuel fill, Prevents paint scratches that can result from a tethered fuel cap Creates a tight seal around the fuel-pump nozzle when the nozzle is fully inserted The horsepower was somewhat reduced in 1971 mainly due to the reduction in cylinder compression ratio, a change which was mandated by GM in order to cope with the introduction of new federal laws which would require new cars to use low octane gasoline in an effort to reduce exhaust emissions. Vehicle Valuation . It is important that these specifications be strictly observed. Spending the $4,000 asking price was also a big step as that was pretty much all the money I had in the world, being a broke college student. Yes the cams listed there are all lower rpm . INT/EXH . As we mentioned earlier, the highest performing 350 V8 that Buick released was with the SP engine code. Now it is ready for the dyno. This ATI Super Damper bolts onto any Buick 350, but it comes with a caveat. 1970 Buick 455, original, was told only 54,xxx miles. The Buick 231 cu. That will help your Buick engine live a lot longer. (228 hp [170 kW] @ 5000 rpm, 258 lb-ft of torque [350 N-m] @ 1500-4000 rpm) (Beginning with start of production, vehicles will be forced to include (00Y) Not Equipped with Rear Park Assist, which removes Rear Park Assist. Manifold Features. This engine produced 275 hp and 325 foot-pounds of torque. [170 kW] @ 5000 rpm, 258 lb-ft of torque [350 N-m . If emissions restrictions had not forced Buick to neuter it every year after who knows what they would have done with it. This 400 engine had the distributor towards the front of the engine, as opposed to the 401/400 nailhead, which had its near the firewall.[34]. Pontiac used the Buick version of the 215. An early-development supercharged version of the 215-cubic-inch (3.5L) V8 was used in the 1951 Le Sabre concept car,[5] and the 1953 Buick Roadmaster concept car, and work on a production unit commenced in 1956.

Photo of the moment: 2020 Seat Leon 1.4 e-HYBRID (204) (Photo: Seat Motor (VAG)) Quick access to automobile-catalog website - type in a browser: a-c.li This is a low-revving torque monster. The cam drive issue is related to the premature wear on the cam chain and gear. ). Of all the GM 350-cubic-inch (5.7 L) engines, the Buick 350 has the longest stroke, which lends to making significantly more torque than any of the others. The computer generated a power curve with an impressive peak 408 hp at 5500 RPMs; 430 ft. lbs. all rights reserved StreetTech Magazine - site developed by ampnetmedia. Set 1978-81 Firebird Buick 231 V6 6 Main Bearing Caps with Bolts $65. Buick's first generation of V8 was offered from 1953 through 1956. The major differences of the 350 in comparison to other GM V8s are Buick's "deep-skirt" engine block construction, the use of cast iron with increased nickel content, an external oil pump, a forward-mounted distributor, under-square cylinder bore sizing, 3in (76.2mm) crankshaft main journals, and 6.385in (162.2mm) connecting rods. This is a grooved cam bearing with relocated oil holes, from the stock 8 oclock location, to a more desired 4 oclock position. The car came standard with an automatic transmission, and a manual was available. A little more compression would not hurt. The bearings were fit to the main bearing saddles. Radius the back sharp turn, smooth and radius as much as you can. The Buick 350 has the longest stroke of all the GM 350 engines. The Special came standard with two-barrel carburetor and 250hp (186kW), where all others had the four-barrel, 300hp (224kW) engine. ENGINE, 3.6L V6, SIDI, VVT STOP/START (310 hp [231 kW] @ 6800 rpm, 266 lb-ft of torque [359 N-m] @ 2800 rpm) (STD), TRANSMISSION, 9-SPEED AUTOMATIC (STD). The major design differences were in the cylinder heads. This helps the Buick create low-end torque as well as excellent mid and high-rpm horsepower. ANother key issue is the tolerances, Buicks like tight tolerances, you cant slap it together using SBC tolerances. Specials. Definitely make more torque .big valves would make more power. The cam was installed along with the timing chain.

[10] This raised the cost of complete engines to more than that of a comparable all cast-iron engine. It was only produced through 1967, being replaced by the new small block 350cuin (5.7L) in 1968. There is a huge amount of support for the 215, principally because of its lengthy use by Rover, spanning a period of 38 years (1967-2005). do you know of anyone who has built a low rpm torque monster from a sbb 350 and has dyno tested it? The same procedure was performed on the oil pick-up tube passage. Your IP: 350 HP / 400 ft.-lbsTQ. Servicing GM's 3800 V6 Engines.
