LA 360 budget build ideas

Also remember most of these theories, rule of thumbs etc.. are originally from race engines not mild - hot street engines. Not saying velocity isn't important but when talking low power stock parts it's being over used, 360 was never meant to be a high power engine so if smaller valves and ports would improve idle to 4500 rpm they would of used 318 heads if it would of increased power. Most stock low power engines suffer from being over restricted thats why bigger carbs cam intakes headers better heads all add power and torque through out the 2500-5000+ rpm power range.
