Big difference between a Boss 429 and you're average 429. But either swap is a waste of time and money. Just strap a blower or turbo to your 4.6 and you'll have more power then a nicely built 429 and quite a bit lighter too.

RE: 429 swap
Just saw on American Muscle, they dyno'ed factory muscle engines from the late 60's. The 427 wasrated 425hp, actually dyno'ed at 657hp, at the crank. Wonder what it would be at the wheels?
As an aside, the 409 was 406hp, the L-88 was, I think, 537hp, and the 426 Hemi, came in at a monster 820hp!!!
I think I would like a 427 under my hood.

My brother just had a 429 builtand my mustang will wipe the floor with it. His 9 is in a 70 Torino Convertible. Small world!!!
The entire FE engine family was a grossly over looked and under rated series of motors for the Fords. If you look back in history the majority of the LEGENDARY FORD'S were powered by FE's. The 427 and 428 CJ's were the engines that Shelby used to establish his reputation of High Horsepowered street fighters as well. Even the Boss 9 would be hard pressed to compete with the Tunnel Port 427's, and the 427 SOHC..

I know if your built up the bottom end of a 4.6 it could handle some serious HP. But I think the idea of stuffing an old motor in would be to put on dual quads, tunnel ram, normal distributor and get rid of the computer. Which I wouldn't mind if I was loaded. But we know if this was still meant to be a street car (daily) emissions would play a factor. But for race and or show who cares right? Good luck for those that can afford something like this.

RE: 429 swap
Yeah, in NC it would never pass inspection until it was 10 years old. I have a CEL for variable valve timing (P0010) that will not clear. I started the engine with one of the plugs off the front of the engine. Now I need to fix it (the local Ford dealer refused to touch the car twice--blaming it on the supercharger). I've had it on for 12,000 miles now...
Trading in you aluminum block for a heavy 385 series (429 or 460) or heavier FE (360, 390, 427, 428) will put quite a bit of weight on the front end as well.

RE: 429 swap
Those are some interesting numbers. One would have thought some of those cars would have performed even better with all that power, or they lost a bunch of it by the time it hit the ground.
I think the problem was they couldn't get the power to the ground.
My dad had 2 cars he raced in showroom stock class. 1 was a 66 Dodge Coronet with a Hemi. 1st year for the street Hemi. You think our cars have problems with traction? In 66-67 the tires were very narrow. He came off the line at idle so he wouldn't sit and spin. His other car was a 69 Coronet R/T with a 440. Had the same problem with traction. This car had so much torque that he kept snapping traction bars. He finally removed them and put in 3/4 ton truck shocks. He raced plenty of 428 Mustangs with his 69 Dodge. Never lost to them even when he missed 3rd gear (sounds like a familiar problem).The 428 was not as strong as people think.The only car that gave his 69 Dodge problems was 396 Chevelles. If he didn't miss 3rd he'd beat them but barely.
You put good, Modern slicks on these old muscle cars (Ford, Mopar or Chevy) and see what they run. I see them running at the track in the 10's and 11's regularly.
I let my dad drive my Stang once. He said off the start it is probably as fast as his 69 Dodge, his 69 would definitely pull away once going though. (darn cubic inches)
