Never install a cat where a cat has never been, they run very hot and if your car isn't protected from that degree of heat it could end in a very bad way.

LT1 came with a cat. You can emiliniate it, when you tune the car that issue will be addressed.

Re: lt1 in a 68 el camino

I believe 96 is the start of ODB II, four O2 sensors, two in front and two behind the cats. Leave the cats off, leave the second O2 sensors off. The computer can be programmed to eliminate the second set and the cats.

If you use the stock accessory mount you may have a problem with A/C compressor clearance on frame and suspension mounts.

It will run very well.

Those heads on the Impalas are decent, better than the Vette heads.

Do a full port, port the intake and a cam in the 218-220ish (intake), 525or so lift, headers and youll have an easy 360+rwhp with a good tune done on the computer. Youll need larger injectors. Should easily get you deeply in the 13s.
