You can get 400 hp out of a 318 just by fixing the compression ratio, and allowing more flow in/out of the engine.According to this article
318 Engine Build - A Parts Book 400HP 318 - Mopar Muscle Magazine it can be done on the cheap. My question is what would it take to make that engine live a long life at a sustained 6000 rpm?By sustained I'm talking hours at high rpm and high loads.Goal is 6K rpm sustained, with a 6800ish redline for when your either lugging the engine in one gear or spinning its nuts off in a lower gear.
I was thinking of building a 5.2 magnum following the same receipt with a few other tweaks thrown in for good measure such as deburring the block,porting the oil pathways,balancing the engine,better valvetrain,etc, then topping it off with fuel injection with distributor-less ignition
How many stock parts could be reworked and reused (ie polished/shotpeened connecting rods)?I can do most of the work myself,and I understand that some new parts are essential.At the same time however, I would rather not pay for Summit Racing's employee christmas bonus out of pocket.
Engine would go in my 73 scamp with a 5 speed manual transmission 3.91 or 4.10 gears, 29" tires...
