we have made over 420 RWHP on SLP headers 
If you get long tubes and want to dump them cheap let me know. I want a set laying around for when I put my car back on the street

Ive been reading these boards for a while also and have seen this issue come up a bunch of times and I still dont know what to think.
I too would really like to see a side by side dyno chart of a car with long tubes vs shorties with NO mods done in between and see what the gains may be and where they occur in the RPM range.
I would think a mag like GM High Performance or Hot Roding or one of those has to have done a test like this in the past.

I have or had (i can get them again) of 2 different cars, one with shorties and one with LTs, the peak was the same for both. And these were bolt on LT1s.
I always reference the GMHTP LT1 shootout in NJ. Russ had the field covered by 2-3MPH and ET by a couple of tenths and he ran the Edelbrock shorties, all the other cars had LTs.

Ive been wondering the same. I have SLPs on my car I bought off ebay. The plug clearance does suck. Ill probably ending up waiting till I find a good deal on some long tubes before I swap.
