i installedd a b&m line lock system on the 1976 supreme yesterday .picked it up from summit racing for a good price and opted for summits version of the universal installation kit .it was by no means a quick and easy install since the kit was missing two key fittings i needed ,but napa came through on that .i would suggest buying the tubing and fittings individually it would be cheaper and you wont have a bunch of fittings lying aroud that youll never use.that being said it works great !! i dont race the car but do like doing burnouts ,and its awesome for that .the 455 has no problem torching the rear tires with a 2:56 gear posi .in the end the line locks will cost me for tires,but no more power braking

 

LOL Well what can i say another problem solved with more smoke! Cheers

 

I don't mind doing burn outs either, but don't care much for power braking anymore, I usually just nail it from a dead stop and light em up, line lock might be nice. RE tires just replaced a set in one car, I found my frequency to burn out increased dramatically as the tires neared end of life, now that I replaced em, haven't burnt out $ince

 

Tires are not cheap no more...
