[QUOTE="barstoolman, post: 10600822, member: 77671"] Here's what I mean......directly from Ford themselves...... "[I]Despite all those modifications, what's most interesting is what doesn't change. Compared to the Mustang GT's standard version of the 5.0-liter V8, the Boss 302's compression ratio is apparently unchanged at 11.0:1 (and still "estimated" according to Ford). Valve diameters stay at 37mm on the intake side and 32mm on the exhaust, and valve lift specs remain at 12mm intake and 11mm exhaust. The Boss 302 engine is more powerful, but it's not a radical revision of the Mustang GT version of the same engine. Ford isn't even claiming a change from the manual-transmission-equipped Mustang GT's 17 mpg in the city/26 mpg on the highway EPA mileage ratings despite the Boss 302's standard 3.73:1 final-drive ratio[/I]." My son has an '11 Mustang GT with 3:73s and Brembos and quite frankly, they drive very much the same when the Boss is in standard mode. We all know about the upgraded internals in the engine but really all those improvements are only going to come to light when the "TracKey" is engaged. [/QUOTE]
