While I agree a H/C LS1 may make close to 100HP more then a H/C LT1 you should know the difference in the way 450HP feels compared to 550Hp won't be nearly as obvious as the jump from 300 to the 450. At some point all that HP becomes useless to u unless you go to the track. To Be honest with you the absolute Happiest I was with the way my car ran was when i just had the teeny tiny GMPP LS1 hotcam in it. Sure it was wicked fast with the new engine but also harder to drive and caused alot more wear and tear on the drivetrain. Also not to mention that with a $400 cam I got to 11.7 in the 1/4 and after that it cost an additional $10K to get to 11.0 and have a reliable car that didn't self destruct every day. If I did it again there is no way I would go for such high power #'s on a street car, it would be less or I'd build a dedicated track car. I'd get a nice H/C setup for your car, maybe refresh the bottom end, a good stall and some suspension parts and you'll be shocked what you end up with.
