Donnow if its street ( oem-style) or race billet under your hood Rick, but Taylor 135 boots is all I ever used, with coated pipes. These are "roll your owns", not precuts. 180 ends on the other side for the full 1967 "medusa" look. And an MSD box you cant find easily unless you carefully follow the wiring!
Header wrap for race cars. It'll eat the headers on a street car. Thins them out to cheese. BTDT.
And academically, IF I had had Mark build me a 4" stroke 468, with my 2.98:1 M23Z, I might even opt for the OEM code 3.07" gears, in lieu of the 3.31 it sports now. I'd also take the pipes down a size to help balance that.
