Thread: 429 or 460?

Tweet

I have a 70 429 in my 57 Ford. It's a lot stronger than the 78 460
in my 78 Ranchero for obvios reasons. I prefer the short stroke of the 429.
I think the 429 was 360 HP stock. Mine has a 280H cam, Stealth manifold
and a set of headers and Dove heads (1970). For a street engine hard to
beat. I wouldn't have a late stock 460 in anything!Except a tow car maybe. The stock 400M that came
in my 78 pulled a load as good as the 460.

There's just something romantic about the 429. Maybe it's the connection to my all time favorite motor, the BOSS 429. I had the option to use whichever I wanted, but chose a 429 for my roadster build.

Using flat-top pistons with D3VE 97cc heads will yield a 9.2:1 static compression ratio, just right for pump gas with a tight squish. Whatever you do, don't use the 1972 D2VE heads. They were so awful that Ford only used them for one year. You could use the earlier 72cc D0VE heads, but you'd have to use deep dish pistons with them. I feel that flame propogation would be better with flat-tops and larger chambers.

Haven't heard a current price on them, maybe Jerry has a contact to find out how much they are.....

I bet they cost more than my entire engine! But....

• The 1970 429 has a 10.5:1 compressision ratio, while the 1978 460 has a dismal 7.8:1 compression ratio.
• The 1970 429/460 cam has a more aggressive cam profile than the 1977 460 cam.
• The 1970 429/460 has a straight up timing chain, the 1978 460 does not.
• (etc.)

Of course the 1970 engine will be more powerful than the 1978 engine due to reasons as noted above (and there are more differences, too). The 1978 engine can be rebuilt to have more horsepower than most people would care to have on the street. Your comparison is really no comprarison at all, except for maybe serving as a study of how emmissions killed engine power over the 1970's decade. Fortunately, the 1978 460 can still be modified to make really good power.

Thanks Paul. It was not making any sense at all to me, but your right, with a longer stroke, you would think the compression would be higher. I'm still going with a 1970 presmog engine and heads, so the extra cc's with a lower resulting rpm for the same hp makes sense to me.
