Identical Cobras? Heck with that, bring on that 460 SPF, I'll race him in a 351 FFR anyday! The SPF wouldn't have a prayer by the 5th or 6th lap, it's brakes would be TOAST!
Think I'm wrong? Try this with YOUR "excellent" Cobra:
From 120 mph slow down as fast as you can to 25 mph. Turn around and come back the other way if you like, take your time. Now, speed back up to 120 mph and slow to 25 mph. This will simulate road course conditions on a track! You won't be "stopping" but you will have to SLOW down for that big sweeper at the end of the straight-a-way EVERY lap. Assume the track is about a mile in length.
I'm guessing MOST Cobras can do that FIVE TIMES in a row (MAYBE)! Number 6 you feel the fade start to come, the brakes are "going away". On the 7th time, have PLENTY of "run off" room, your going to need it! Your brakes will be TOAST!
So how many laps of a ten lap race did you do? 6? 7? Heck, the freaking VW you left at the starting line is coming dude, and he's coming for YOU!
And you want MORE horse power? Hell, you can't even STOP the car with what you got!
Drag Racer are you? OK, use a 460 bored and stroked and go get 'em for 1/4 of a mile and ONE stop! But if you can't run in the 9's it sure is going to be embarrassing when that TINY Buick V6 powered Cobra "spanks you"!
So the point of a "giant" motor was what??? Oh yeah, it FEELS and LOOKS so cool dude (uh,,,,,pass the wax please).
