Header questions
 

I have a 67 c10 that was originally a 6 cylinder and been converted to a v8. The motor is mounted in the 6 cylinder mounting holes on the frame closest to the firewall. And I have a 4 speed manual. 1. Is there a long tube header I can buy that will fit without any modifications? 2. Or am I going to have to get a block hugger style/shorty headers?

Re: Header questions
 

Most likely C3 Corvette headers will work great. They should clear everything including clutch linkage and tuck up above the bottom of the frame. BUT this is just an assumption on my part based on a set of 4x4 headers I have and a set of 'vette headers.

Another possibility is a set of 4x4 headers from a 67-72.
