I'm with Pete on the concept of trap speed as a great indicator of actual hp applied to the road, (strip), as e.t. is useless in this regard.
Although my only dyno runs (stock) with my car cranked out only 326 whp. With a good intake ("forced air"), and free flowing exhaust listed below, it actually trapped over 117mph. in the qtr, on a humid Florida night at over 80F. That's 7mph. more than it was able to do bone stock.
If I ever make the leap to all the top end mods, I could only hope to be in that 550+chp. territory. That's phenominal for a naturally aspirated, stock block,350 Chevy.
LT5's rule, and they "don't need no stinkin' blowers".
