Having both, is the key, but controling the power is the art.

Getting traction with our Cobra's can be an issue, but a lot of owners (even racers)
don't have a clue on how to set up the drive train, chassis, suspention, tires and even steering.

Just like you high end engine builders, every make of engines and every engine is different. You can have two exact blocks, heads etc,...but it can be amazing just how different they become, no two are exactly alike.

Every driver is also different, some prefer TQ other HP, some both. One driver likes the car loose, some tight. Weight bias front to back is also critical in most cases, even drag racing.

I would say most people don't think about how shocks and springs can effect any kind of driving, and how to set them up. Most of the time, to get a car dialed in, you must have 4-wheel scales. When I set up my Cobras suspention I eye balled everything, but when I set up the electronic scales, I was amazed just how bad my eye balling was. lol....

Being 54 years old, I grew up in the "Pro-Street" years, so Ilike the power, sound, feel and smell of those cars, but also like the "Pro-Touring" of todays muscle. My first build as a teen was a 1977 Camaro. 468 RATT with a mechanicl cam on AV gas. Muncie rock crusher, pro 9" rear with fats and a 4-link.

Anyway, I need both high TQ & HP, even if it's over kill.

You'll have to try and talk me out of a solid roller cam, even with a lot of idling on the street.
What do you think of Isky's roller lifter on the street ?

Oh, do you happen to have the TQ & HP results down real low rpm, like say, 2,000 or 2,500 ?
Or a estimated good guess ? Just curious as it's a torgue monster.

I almost went with a 460 based big block and probably should have but I think I will be okay in the long run. I ended up keeping my 427 but having Brent from Lykins Motorsports spec me a cam and then I Lance do all the machine work and freshen my Brodix heads. I am throwing a ton of gear and T56 speed at the car so I am pretty excited to experience the results.

If you are REALLY serious about a 460 based big block then have Lance or Brent build you a motor and get on down the road. Personally I would spend the extra $2,500 or so dollars and get the A460 block and punch that sucker out to 570-600ci with a hydraulic roller. You should be able to make 750hp and enough TQ to tear your car in half on pump gas. I literally had to talk myself down from the big block. My car wasn't a complete turd before we dug into in and we thought it was down about 75-100hp and had a ton of mismatched items for what the intent of the car was. I'm not ruling out a big ci motor in the future but for now I think I will have all I can handle for a street car. Fresh 427W that should peak around 6000rpm with a 6-speed T56, 4:30 gears and 325-50-15's We have had the car down since August 2016 so I plan on having to learn to drive the car again as it should be on another level.
