If you're dead set on only using original speed parts, 71 Mustang coupe, 429 SCJ, 4 speed, 4.30 Detroit. The 385 stuff came along too late to really make an impact back then, but pound for pound, I'll put that stagger valve SCJ notch up against any Hemi E-Body, Ram Air Bird, ZL-1 Camaro <span style="font-style: italic">or</span> FE powered production Ford. </div></div>

Let me preface this by saying I loves me some 385's. I had a 796 hp 514 in my 67 Fairlane and it was a BEAST. However, I think you give up too much in a 71 Mustang -- a bit on the heavy side, and that 429 is a heavy lump. Same thing hinders the 351 Boss, IMO -- awesome engine, but car is too heavy.

Here's my old '67 -- not really Day 2, but still one of my favorite cars.

Love that Fairlane. I had a Lime Gold 67 500XL with a Cleveland/Toploader setup for power. Miss it every day.

On the Mustang, yeah, the 71 gives up some weight to the 68. But them heads though. Im picturing a 71 coupe with Edelbrock intake, three barrel Holley, 2 inch primary headers, and a massive GK solid roller. I'm a die hard Windsor guy, but there's no arguing with the canted-valve stuff when it's breathing right. Using modern speed parts the inline valve wedge stuff can compete. Using only old school stuff? I dunno.

Boss 429? Ive ridden in true Day 2 Boss '9 and its a face-melter. They'll run if done right. Problem with the Ford Hemi stuff is paying the tab.

'67 sounds like it was a sweet ride.

Boss 9 or 71 CJ 429 work best in FAST cars. With a relatively inexpensive stroker kit and a good OEM block, you can get close to 600 cubes. You're constrained by factory intake (ported of course), carb (massaged extensively), and exhaust manifolds (extrude honed), but you can still make some serious power and torque. A few years ago someone with a 429 CJ Mustang was the first person in the 9's in a F.A.S.T. car.

71 Sportsroof weights are around 3,650 for a 429 car; not great, but not as bad as you would think. Had 375 hp and 450 ft/lbs to move it around. Looks like around 3,300 lbs for a 68 CJ Mustang, with the 428 rated at 335 hp/440 ft lbs. I'm still going with the 68 as the better car, but I think it's close.
