I was thinking about buying a Mustang the other day because there just easier to find. Then i got pissed off at myself for even thinking that. Then i started comparing the two and i came up with a question that i couldnt think of an answer for. Where do you guys think a stock displacement, pump gas, naturally aspirated, 3 valved, street driven 4.6 Litre Mod Motor would, say, run into a brick wall when it comes to power output. Now where do you guys think a stock displacement, naturally aspirated, pump gas, 2-vavled, street driven 5.7 Liter LS1 or LT1 would run into a brick wall when it comes to power output?
