The perfect Engine Calculator App for Professionals, Racers and Auto enthusiasts! Satisfaction Guaranteed!Save time and money by experimenting with parts specs before permanent mods are made! Try different parts combinations until finding the desired displacement or compression ratio!A true Professional App made by Professional Developers. This is not an abandoned freebie made by hobbyists!Excellent user interface designed to provide the right look and feel of a performance tool!This what Engine 2LBox will do for you and your ride:* Engine Displacement. Calculate engine displacement in cubic inches or cubic centimeters. Experiment with overbores or stroked cranks! What if combine this block with that crank? You can do it with this App! * Compression Ratio. Static or dynamic compression ratio calculation! Easily determine your engine compression or experiment before purchasing pistons, head-gaskets or ordering machining operations! Need to choose a cam but need to know how will it affect your running C/R? You are just a few taps away! * Deck Height. Get your deck height based on your block's deck height, piston's compression height, rod length and crank stroke. No more guesstimating! * Cylinder Head Power Potential. Interested in a set of cylinder heads for your engine but would like to know the amount of power you can get out of them? Easy! Just enter the head intake flow data and the number of cylinders of your engine and find out! * Valve Lift. Want more lift without a new cam? A quick and easy way of injecting 10-20 hp to an engine is with more valve lift! Depending on cam, head-flow, compression and other factors you can get away with more hp by simply swapping your rocker arms! Experiment with this calculator before purchasing parts! * Unit converters. Convert cubic inches to cc's and cubic inches to liters. * Rod/Stroke Ratio.Determine optimum ratio between rod length and crank stroke to minimize piston, ring and cylinder wear on high output engines.* App includes valuable engine data like bore, stroke, rod length, block deck height, displacement in liters for Chevy, Ford, Mopar, AMC and Honda engines! Examples included for every calculation! You can't keep modifying your engine without this App! Download now! Constant and free lifetime updates!
