| RE: headers on before or after- both. |

| My FPA try-y's in '69 mach1 went like this. I removed the engine, chased the threads with a btm tap and put heil-coils in all the top threads as they were about rusted away. trial fit the headers & gaskets on the engine while on the stand. the goal is to get all the bolts in by 2 fingers. I then put the engine mounts on. I trimed some part of the metal off the mount as it was allmost touching one of the pipes, I don't recall which side. I strongly recomend getting new mounts if yours are old and deformed/splitting. I also ground a little off the bottom rear left edge of the block, right below where clutch pivot would go as the one pipe was just touching the block. I just could not beat dents in those new headers with the $200 ceramic coating. Now for the fun part. you need as much room to work in, but there is none so you got to make it. remove the frame mounts and master cylinder. next time I will remove the bolt in cross member, outer tie rod ends, idler arm, pitman arm and power ram. Put the engine back in with the drivers side hedder laying in the car. bolt the transmission on, C6, loosen the rear tran. mount hang the engine from the hoist, go up and over as far as you can and bolt the header on. most bolts are done from below. remember 2 fingers! swing to the other side and repeat. the pass. side header goes in from below. Install the engine mounts and check for clearance on the top bolts for 1,3,5,7 and the steering box. For those cylinders I ground down the bolt heads for extra clearance on my big block shock towers and still put shims between the engine bracket and rubber mounts to get the clearance I was happy with, about 3/16" shim. The starter goes in from below with the idler arm unbolted and the 3 bolts go in from the top. I suggest making a bracket to go in the bolt holes just above the pan rail on pass. side to hold the starter cable away from the header. do this while on the engine stand. I might have left out some choice words or 3 but I do like my headers w/o running aground etc. Courtney Bolze. |
