It is a good idea to install the timing chain at this point as there is very little room between the rods and the cam. Allowing for better flow reduces exhaust reversion and increases scavenging, which allows for cleaner and cooler air to enter in the combustion chamber. Build a 350 or 383 you'll be happy. commercial copying, redistribution, use or publication by you of any such 26.

I haven't taken the heads off the RP block but I think the difference between the 74 and 69 motors are the cylinder head volumes are less on the 69 giving it the higher compression. A clearance of .004 to .005 is good. The gears must be packed in assembly lube or the pump will never prime. When massaging cast iron, use a fine-tooth bit, coarse bits will jump around, causing more damage than good. The GS350 made its name from 1968-1970 as an absolute performance machine. Does that sound reasonable? So basically, any builds under 400 hp and nothing needs to be done. Some product and company names mentioned on this site may be trademarks of their respective owners.

Buick used a five-bolt pattern around each cylinder, while Oldsmobile used a six-bolt pattern and a wedge combustion chamber, which allowed larger valves. Tightening emissions controls would cause the engine to drop in power still further, a little at a time, through 1976. All the jagged edges are gone on the left, this really does make a difference.

The difference between this measurement and the previous measurement is the bearing clearance, in this case .002. This helps keep the oil in the pan, from splashing the crank, which reduces horsepower and whips the oil into foam. Some of these Buick V8s, such as the 350, 400, and 455, had the same displacements as those from other GM divisions, but were otherwise entirely different engines. Garage, PowerNation do you know of anyone who has built a low rpm torque monster from a sbb 350 and has dyno tested it? Morgan used the Rover version in its Plus 8. the 212 would rev higher as for its design and will give up Alittle power lower but still works. Like the cylinder heads, the stock unit is made from heavy cast-iron and does flow exceptionally well. Copyright. I wish I had 7 grand, I would buy one!
