Repco-Brabham also based their F1-championship-winning V8 (SOHC per bank) on the Oldsmobile 215 turbo block, and subsequently developed it into a 5-litre quad-cam 32-valve sports car engine. Main bearing caps on 327 engines should be torque in two steps to between 60 and 70 lb-ft, while 350 engines should be taken to 75. This essentially creates a dual-cam effect, where at low RPM, the cam is more subdued, but once the engine hits 2000 RPM, the lifters stay pumped up, allowing the cam to do what it does. https://streettechmag.com/2015/03/23/porting/. 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. 15-35 . The cam was installed along with the timing chain. Going with aluminum or steel long-tube headers is a great way to reduce weight while opening up flow. 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. The all-aluminum V8 engine was dropped after the 1963 model year, but was replaced with a very similar cast-iron block, aluminum head version for one year, and then in all-iron versions. In order to tone down the low RPM effects of the cam, we used a set of Rhoades lifters which feature a high-bleed off rate under 2000 RPM. 220lbft (298Nm) of torque was produced at 2,400rpm with a Rochester 2GC (DualJet) two-barrel carburetor and 8.8:1 compression ratio. For that reason, the more common Buick version (which looks like a traditional Nailhead V8) has emerged as more desirable to some. 26. All of this adds up to an extremely durable motor, which with a little tweaking, is capable of supporting 1,000 horsepower.
