Hell yes I've got a 66 with the original engine i stroked the 289 to like a 331 i would have gone to the 347 but for an original 66 block i didn't want to take the chance of it cracking. As is everything else I put in it titanium valve springs racing roller rockers etc. As is on the Dino it peaked at 548 hp. I'm just waiting to find the correct twin turbo set up. Ot isn't as pretty as yours my interior is all new white pony. As for the exterior it looks like a bit of a rust bucket😅😅 also 66 is before emissions were passed so i have basically the same exhaust as the Shelby GT 350. Hooker headers Glass pack's that shoot any unburned gas out both sides ya the exhaust goes out in front of my rear wheels. She sound's amazing I love in Utah with the snow its been hard to drive so I usually park it from December to April 1st. Fire her up once a week to make sure she's good😊
