Headers and Shift Linkage - The 1947 - Present Chevrolet & GMC Truck Message Board Network

muckyp · 12-29-2010, 10:16 PM

I need some help/advice. I installed some Patriot mid length headers on a 454 with a TH400 trans. It appears that the exhaust will now interfer with the shifter linkage. I have done a lot of searching but don't seem to see anything about TH400. The posts I find suggest the Lokar cable shifter or the Lokar rod style linkage. What have you guys that have used the Patriot or similar headers done about the trans linkage?

It is very common for headers to interfer with shift linkages. Especially with a big block. You may be able to change out your factory linage for one from Lokar or another aftermarket brand.

Lokar cable shifter is what I used. It works great and wasn't terribly difficult to install.

Has anyone used the Lokar rod type trans linkage in a similar setup?

i just installed the solid linkage, took about an hour to figure it out but worked great with shorty headers...

Project 67, what engine and tranny are running and do you know what brand of header you have? Any pics would be great. Thanks
