Here's some of my latest updates for my 65 Fastback:
I have installed 1.9" int, 1.6" ex valves, with Lunati roller rockers. Topped off with cast aluminum "Cobra" valve covers. Heads and maniflod are port matched. The heads completely ported...actually flow better than a set of GT-40 heads.
Changed the cam to a Crane hydraulic flat tappet energizer with .498" lift
Changed to a Weiand Stealth manifold.
Bore: is .030" over with TRW forged aluminum piston and gapless cast iron street rings.
On the list of things to do tis winter is....a 5 speed conversion and install disc brakes.
Oh! did I mention...first 1/4 mi: firstname.lastname@example.org using a 50/50 mix of Turbo-Blue and Sunoco 94
