This is a previously-owned, adult-extra-large (XL), blue long-sleeved hooded shirt with “390” printed on the front and “V8 / 390hp Engine” printed on the left sleeve. It measures approximately 25 inches (from underarm seam to underarm seam) and is in pretty good condition for a used item (No Boundaries brand, 65% polyester / 35% cotton). A V8 engine is a V engine with eight cylinders mounted on the crankcase in two banks of four cylinders, in most cases set at a right angle to each other but sometimes at a narrower angle, with all eight pistons driving a common crankshaft. Most racing V8s use a single plane crankshaft, as it allows faster acceleration and more efficient exhaust system designs. Lately, Chrysler and GM have designed larger displacement V8s out of existing modern small-block V8s for use in performance vehicles, such as Chrysler's 6.1 L (372.2 cu in) and 6.4 L (390.6 cu in) Hemis, and the LS7 7.0 L (427.2 cu in) version of GM's LS engines.
