If i can give anyone a piece of advice when installing the headers…make sure you follow directions and put the drivers side header in when your dropping in the new engine. I didn't and had to role the engine on its side until the transmission hit the tunnel and started lift the car…and i still had a bear of a time. All clearances are good and the transmission is sitting down at a 3 degree drop. These kits are going to save a lot of people time, money and frustration!

The outlet of the reducers are 2.5" straight tubing, so you'll have to adapt the end of your exhaust to fit to it if it features 3-bolt flanges. If you want to be able to butt connect it to the end of the adapters on the headers with the same type of coupler clamps shown in my photo above, we offer them in a 2.5" version as well.

The stock idler arm for a 69 Camaro is 5.25 inches long center to center and this is what I originally had on my car. It cleared the 302-2 oil pan but just barely and I had to dimply the header to fit which I posted pictures of above. The moog replacement idler arms for a 68 and 69 is 5.375 inches center and center had the best clearance at the oil pan but the clearance at the passenger header was about the same. I found out the 67 used a 5.8 inch idler arm so I ordered one of those Proforged part 102-10003. The clearance at the oil pan was about the same as the 5.25 which confused me a bit because I expected it to be better but I believe this is because the 5.8 inch arm allows you to have a little more steering throw because of the longer length. With the 5.8 inch arm there is still a header clearance issue but it is less than with the shorter arms. I with my dimple I had minimum clearance with the 5.25 arm but here is pictures of the clearance with the 5.8 inch arm.

Net Net there is no solution to the holley long tubes without modification. You will either need to move the engine back a half inch or so or modify the header. The 5.8 inch idler arm from a 67 Camaro gave me the best clearance at the header but its really close at the oil pan. The 302-2 pan will fit with the tru turn setup but the steering to oil pan clearance is really close.

Stock pitman arm lengths:

Non power steering 5.25 inches
Non power steering quick ratio 5.8 inches
Power steering 5.8 inches

Stock Idler arm
67 5.8 inches
68-69 5.25 inches
Moog replacement part K6099 5.375 inches
67 replacement Proforged part 102-10003 5.8 inches

These pictures are with the holley 302-2 oil pan, holley mounts, 1 7/8 long tube headers and a 5.8 inch pitman and 5.8 inch idler arm.

Here is where I got most of my steering info:

Put the nut into the wire then push it up against the frame were the bolt comes through and push the wire until it bends to the angle of the frame. I was able to put the nuts on the bolts as easy as having direct access

Cwylie should have it back in the car soon and be able to update everyone on the compatibility improvement.

Todd,

Any idea if these pans shipped to Jegs yet? Have one on order for a few weeks now. Getting anxious.....
