A 429 was everything the 427 was and even better (except for the heads). Large bore and small stroke for high RPMs. The 429 only had a 3.59" stroke which is not far from a 351/352 stroke of 3.5". The 390/406/427 had a 3.78 stroke which was not far off of the 460 stroke.
The 428 crank was too much stroke for high RPMs. A 4" stroke with a poor oiling system was a disaster. The 460 only has a 3.85" stroke. Very large bore with a moderate stroke. fine for 6500RPMs with no special oiling system mods. Try that with a center oiler FE and you have serious issues.Last edited by Mercracer; 03-18-2010, 04:53 AM.

This is what i found in regards to a 428 crank in a 390 creating a "410"
The stock 428 is actually 426.54.
A .020 plain 390 block upgraded to a 410 = 414.24
Only 12.3 less than a 428.
A .030 plain 390 block upgraded to a 410 = 416.28
Only 10.26 less than a 428.
And the difference from 428 is by bore so it affects torque less, and torque is what you're really after in a heavy car like a Galaxie. Meanwhile, the 24 or 26 cubes you're gaining over the 390 is all stroke which means lots of torque. Upgrading a 390 to a 410 allows you to nudge into 428 territory without the expense of getting a worn 428 block or the worries punching a 390 to 4.13 bore.
And if you only overbore that 390 block .020 or .030 over you're likely to get another rebore out of it 175,000 miles down the road. Whereas a used 428 block at .030 is likely as far as it can go (unless it's a CJ block).
i dont mean to thread jack but i thought this would be good addition to the conversation. could a bored out 390 with a 430 crank indeed be better than a 460? maybe cheaper? maybe have more mods? i dont want to start a piss match i was just curious.Last edited by Leo; 03-18-2010, 08:23 AM.sigpic

He puts a 460 in a box switches it to propane sells it for 800 and doesn't even have a picture of a under hood shot.1984 CV tudor 351W, 4bbl, 5-speed best time in the 1/8 8.39 at 80 with 1.80 60ft time.

I seriously doubt that has a 460. People are goofy...like the ones who say they have a 302 HP engine because they think the engine size is it's horsepower...sigpic

Cars seem to be getting too damn heavy for their size, if I may digress slightly.
Anyhoo, yeah, the stock 460s won't give you horsepower - what they will give you is gobs more torque at stupidly low RPMs, which can always be fun. It's not about maximum horsepower, after all, it's about the amount of horsepower/torque across the entire spread of your RPM range....Last edited by King_V; 04-02-2010, 12:27 AM.1987 Ford LTD Crown Victoria 2-door Coupe - perpetually "sort of" for sale...

Mind you a 400 cid engine is usually going to make a fair bit more torque than a 302 inch motor will, so even if you're even hp to hp, the torque of the bigger motor will still win. I realize the power levels are a bit apples to oranges when you talk net vs gross hp, but my point was still that in the early 70s, a car the size and weight of a panther would have had more go power under the hood.
agree that modern cars are damn heavy for as big as they are. Its all that safety equipment they carry now. The crumple zones, side impact beams, miles of wiring for abs, air bags, crash sensors, etc all packs on the pork. of course, considering how much more likely you are to survive a major crash in a modern car vs a 70s car, its probably worth it.Last edited by gadget73; 04-03-2010, 10:46 PM.86 Lincoln Town Car (Galactica).
