Did you peep his trap speed Stu?
In a thread I made, he was telling me that a bolt on cammed 5.3L ecsb should run mid 7s n/a.

wow. 460whp is more than Jons cammed, full bolt on, little head work LS2 put down. You sure that wasnt with spray? Also did the dyno hook up to your lugs or were you on a roller dyno? Sorry, thats just a really high NA 5.3 number.
Funny how this has been mentioned several times and just now are people getting on it. Read the whole topic again :lol:
