Old vs New
My uncle wanted to see how his stock Mach 1 would fare against a modern muscle car, so we did 3 runs, all from a dig, on his driveway/private road. He even had his wife stand in front of our cars with two hankerchiefs to start each run. His car easily sounded much more intimidating than mine, but I took each run pretty easily. Now he wants to know how easy it is to mod an LS1, because he wants to throw one in his canary yellow 1980 Camaro and turn it into a monster.
My dad got wind of our little match and decided he wanted to match his old Duster 340 against me. His Duster is far from stock. Our first run was from a dig, and I took him by half a car because he had a bad start, our second dig run he managed to hook it and he had 2 car lengths on me by the time I hit 40mph. We did one more run from a roll starting at 50mph, and that ended with him taking me by half a car, with me starting to close the gap as he reached his top end and the T/A was still accellerating.
That Duster of his is a stone cold killer at speeds up to about 140.

Nice runs, I would have liked seeing that on video. I have a sweet spot for those old Dusters....

I think that would be a ok race, i have raced a cobrajet 428 and won, I think there high 13 second low 14s car not that fast. The would be a better run for a LT1.

2000T/A, it's so hard to get a fair comparison of what the old-school muscle cars were capable of. With 5.0s you could pick up 2-3 tenths of a second by doing a "ten-minute tuneup." With the old-school cars, though, you could pick up a full second or more just in the tune of the car. Things like proper jetting, timing adjustments, converting secondaries from vacuum to mechanical etc... made a huge difference in the performance of those cars.
You couldn't even get a good idea from the old magazines because some cars were ringers from the factory, and some weren't even tuned.
BTW, the 428 SCJ wasn't the same thing as a CobraJet. More aggressive gearing, tuning, and engine internals made it a little more optimized for drag-racing. They're hard to come by. I know an otherwise factory stock one would be comparable to an LS1 if it were tweaked and had similar traction. They'd both go 12s, my money would be on the SCJ. I wouldn't bet too much though, it'd be a close one.

The early 70s Mach 1s were my favorite mustangs of all time

I beat a highly modified 429 Boss Mustang with the almost stock 95 T/A I had. A young guy was driving his daddy's Mustang and thought starting a race will doing a brake stand was going to make him go fast!
After the race he pulled up next to me and asked what I was running because the Mustang has pulled 10's on a drag strip. I hope he didn't tell his dad he lost to an almost stock LT1 T/A!

He would be a great race for a stokc ls1 running a 13.6-13.7 but i ran a 12.8 so he lost by a good amount.
