Big Block A-Body K Member Selection

I'd go with the factory K 1) you allready have it 2) it was built by the factory to install the big block and 3) you juat can't beat the cool factor.
Thanks for responding.

Agreed, although I am a purist at heart and have the complete setup including exhaust manifolds that might be able to put another original back on the road. I was also lucky enough to find a complete, albeit unrestored ā€˜67 383-S Fastback.

The car Iā€™m building is a former /6 so no worries about originality. My other concern is the un-boxed idler arm on the ā€˜67 only.

Again, thanks for responding!
