Thread: 383 bumpstick question!

Tweet

im tryin for about a 2800 to 5800 power curve captain. 25 ft/lbs isnt all that bad considering it probably more than made up for it higher in the curve. maybe i shouldnt get too greedy with the duration and go with the XE 276HR. Hmm...... decisions, decisions... Chevy HiPerformance Mag did a 383 called the twister that pumped out 480 ft/lbs with that same 282 cam. It was quite streetable with 436 ft/lb at only 2600 rpm, maxing out at 486 ft/lb at 4200rpm. Im hopin this power will get my 3300lb nova in the high 12's considering im gaspin for air myself at 3600' elevation!!!

The duration issue changes when you spread the LSA. By going wider you can run more duration and get away with it. That's why the companies routinely do it. Either of those two cams will get you what you're after. They should put you solidly in the 12's.
