This app covers Casting Numbers associated with the 348,366,396,402,409,427 and 454 Big Block Chevy Engines from 1958 thru the mid 1990's.
With so many combinations of Bore and Stroke, Valve Sizes, Crank Styles and Intakes that were used it is hard to know exactly what you have in your hands at the Swap Meet or while checking those CLAIMED "Numbers Matching" Auction Vehicles.
This app will give you information on Big Block Chevy Engines Blocks, Heads, Cranks and Intake Manifolds. Other Specifics of valve sizes, accessory mounting holes, forged or casted cranks, and much more on some of the items.
This app is a Native App meaning it's loaded on your mobile device, not depending on locking into a website for it's information. This has NO connection to a useless app that was offered a year ago.
