i was looking at the numbers in the sticky and i was just wondering, if our cars from the factory are supposed to put down close to 300, why are header , exhaust, lid, ported t/b, maf, and tuned cars not making much more than 300? or is the 300 to the ground inncorect and im just ignorant of the facts. i havnt had my car dynoed yet but i have most of what i listed above and i am expecting 350+. is this unreasonable? sorry just thought most of our cars were making more.

Bone stock I put down 297whp and I can't remember the torque. Cars with headers, exhuast and lid seem to be about 330whp.

My car stock put down 297rwhp/308rwtq as well....

Lid/Longtubes/Tune/Stock LS1 intake put down 352rwhp/360rwtq....

After I installed the 12bolt and 3.73s with dual cutouts, I dropped to 344rwhp/356rwtq....

These cars should dyno around 3xxrwhp stock. Most of the ones that have dynoed with lid and full exhaust and are still close to 300rwhp are probably auto cars or are on a mustang dyno, so....
