| RE: What are the HP limits |

| It is sort of a redline max that dictates safety for the engine, not HP. I built mine conservatively...Crane cams did a computer profile and said 480 HP (optomistic I think...more like 425 HP), but the next cam up was capable of 540 HP according to Crane...but at what rpm? You are definately safe under 5500 rpm....I hear the rods are good to 6500 rpm without shotpeening and polishing, but it must be at a limit, so I don't do it. Build a high torque low HP, low revver for the street, and you'll be safe...and Happy!. The cam dictates this. Compression ratio doesn't increase HP dramatically, but it allows you to use a cam that will. Look for a cam with a broad torque curve down low for the street and forget HP figures, For drag racing...go with the high rpm, high HP cam and be prepared for heartbreak from time to time. Sorry I can't qualify this more. |
