Re: Header Clearance
I installed a 6.0L into my 69 Camaro and my driver side header hits the top of the power steering gearbox. I am using dirty dingo Double D adapter plates along with Dynatech 715-31425 headers. I know a lot of people swap out the ps gearbox for some type of quick ratio version. Does anybody know if one of these is smaller and may allow my headers to work? I am also interested in other options that I may have. I really don't want to change the adapter plates since the engine is already in the car. If going with another set of headers is my only option I can look into that as well. Thanks in advance.
I'm using 1-3/4" Holley-Hooker headers with 2-1/2" collectors and they have 1/2" clearance all around the ps box.
The motor mounts are also Holley.
Are your adapter plates adjustable ? Would moving the engine 1/4" or 3/8" solve your problem ? Just redrill the adapter plate mounting holes.
