So i finally go them bolted to my 383 LT1. I dont know why people have soo much trouble with long tubes.

Drivers side went in in like 30 seconds no problem at all. Had to do it from the bottom with the filter off.

Passeger side. We jacked the motor up as high as possible, then pried it towards the drivers side. The jambed the header in from the top.

I also have a LT1 started of course and it had alot of room around it.


They wernt bad to install tho.

***NOTE the knock sensor will not work on the passenger side. I dont have one in right now since I couldnt get the plug out of the drivers side. I think I am gonna run a 90* elbow off the block so the knock sensor doesnt hit the primary's. I had this dont on my old 355LT1 do it would detect knock as easy.

I will post picks when i charge my cam.
