Hi,

I just love the 427 has such a deep low rumble at idle, harder and harder to find people now a days who recognize how good they sound, also performs well, had one in mt 67 Shelby for the past 30 years.

That dude is super smooth. Anyone who has ever auto X'd knows how hard it is to go fast and have smooth & accurate transitions. For all the power that baby really hooks up. Fun to watch and hear.

Thank you, Scott does make it look easy but in reality it is very difficult because it will break loose instantly if he is too quick on the throttle. He only got to 75% throttle twice on that run and the traction control pulled timing back to 15 Degrees BTDC when he did. There is a movement to handicap the car with a 2 second penalty going in because of competitor complaints. All cars with less than a 100" wheel base or any tube frame car under 3000 lb will be assessed 2 seconds to "equalize" the competition. Our reward for making the car handle, accelerate and stop is more work! I guess it is a compliment to our efforts.

Latest outing with CSX3170 last weekend, over 9200 several places. The red "heads up" reflection on the windshield indicates the traction control is pulling timing, as much as 20 degrees. We have a way to go to hook this thing up on concrete.

It is hard to believe this performance is from a 50 year old car. I am still amazed every time I drive mine.

Actually if will be 54 years old in November, I bought it in November of 1965. They are so short, narrow and light it takes a very skilled driver with quick hands to extract the performance that is within. This is a very extreme example but it was a handful even brand new with about 1/2 the HP it has now.

It is described within this article but it is an FE based aluminum engine that makes 820 HP @ 8200 and 562 lb/ft@7000 red line 9400 rpm, it is 440 cid.

Congrats to Cobra498 (aka Cobra #3170 in other places)


What an engineering accomplishment to transform a Cobra into this.
