is it at all possible on a stock headed lt1 to make this kinda of power with this cam....CC 503 375 HP @5000 RPM 426 TQ @ 4000 Needs same stall. he is claiming this is to the wheels? i've never seen anyone post this high of number for this cam?

when mine was a 355 with 306 i didn't make no where near that amount? and now i'm right at that with my 383 and 306 with shorty headers??

 

Maybe to the front wheels.
