Wanted STR-15

Here's pics of STR 15's ,I have had these since mid 80's I replaced a stock 4 bbl set up on my high compression 383 with the thermo-quad STR on my Cuda and on the first test run I pulled out on the street and punched it......boggggg.I had traded it for a three piece glass Road Runner front end and thought for a second that I made a bad deal .Second time punching(this time pissed off!!!)same thing boggggg.....but this time stayed on till about 3200RPM then BANG felt like someone hit the the Nitrous button.These intakes take away the bottom end and put it all on the top end I've been sold ever since.I may part with one "make offer".
