We are doing an engine switch from a 327 to a Z454 on my '64 Chevy Impala and want to make sure there is enough room on it for new headers also and advice or personal opinions on what to use? What to stay away from?
Thanks for all you help you have made this partial restore much easier with your knowledge and advice it comes very much appreciated!
I have a Mark IV 454 in my 61 and run Sanderson Headers block huggers. They fit well with no issues with steering shaft, A-arm shafts, or 4 speed clutch Z-bar and linkage. Good people to deal with, also. The block huggers give much needed ground clearance, and they slid right in and no leaks.
