Others are considering breathing new life into the 335-series by building stroker 351M/400 engines, but their larger bellhousing patterns will be unlikely, IMO, to find the level of acceptance that is seen by true small blocks.

Apr 10, 2008 · The 351C oiling issues can be remedied with an external oiling line, and some pipe plugs in key places in the oil passages, after which, the 351C becomes a nice, solid, high rpm motor. The 351W, in contrast, has huge 3" main journals, which are too large to run at high rpm, as all that surface area creates a lot of friction and heat.

Jan 21, 2010 · A 1970 4V 351C makes 300 horsepower at 5400 RPM's. The 351C is a racing bred engine. Throw some cash at it and it will scream. The stock crank will withstand turning at 8k and aftermarket forged cranks can do 10k plus. Just let it breath and it will run away from anything. The valves in a 4V cleveland head are HUGE.

Feb 7, 2011 · Yes but it will be some work. Any 5 speed that will bolt to the 302 or 5.0 will also bolt to a 351C. The problem is the amount of torque and hp that the Cleveland makes can destroy all but the strongest (most expensive) 5 speeds on the market.

Apr 13, 2009 · Start the engine and run it at 3000 rpm. Set the timing to 36 - 38 degrees (use a timing light with a built-in advance) Return the engine to idle an check the timing - that is the maximum timing you can safely set at idle unless you recurve the distributor.
