Well, he doesn't have to change the heads. A stone-stock 429 passenger engine has enough power to shred the tires off a Mustang. These engines were intended to drag around two-and-a-half-ton luxury cars. The Mustang is barely half the weight of these huge cars.

More like $400 to get it into the car. If there is no transmission included, he'll also have to get a 385-compatible C6 at a yard. Any big Ford, Mercury, or Lincoln can provide this trans, even the 351M equipped cars. Some work will be required to attach a shifter to the trans.

That looks exactly like a Windsor. The 429/460s I have seen with normal heads have had flat top valve covers like the Clevelands. Regardless, I honestly have not seen a 429 without hemi style heads in a classic mustang. Surprising that it will fit.

This is the 71 Mustang 429SCJ:

Take it. The C6 is your only realistic automatic. Manual on this conversion would be a can of worms.

Well, for that you'll need the big-shaft toploader, that'll run you easily over $1000, then you'll need a 429/460 bellhousing, clutch, flywheel, then you'll need clutch linkage, pedals, etc, shifter…

Suffice to say even if you have to get the C6 rebuilt, going 4-speed will cost three or four times as much.

The flat valve covers are oem most aftermarket ones look like a windsor.Yeah it will fit its kinda tight so a tiny bit of shaving the shock towers will help later on when you change the plugs.Yeah a toploader for a big block isnt cheap to do id look more in to a tko or something with a over drive on it.
