so what do i have here ? a 429 1971 block,1973 heads,1976 intake and 1972 water pump ?

No, not necessarily.

The numbers you looked up are not casting dates, they are engineering revisions, and they indicate the revision of the part in question...not the date that it was created. For example, D1VE blocks were not used only in 1971, they were actually used from 1971 through 1978. Same kind of story with the other components you noted.

Taking into consideration the info you have provided, best assumption is that your engine was likely made between 1973 & 1978. But based on the actual numbers provided, my guess is that your engine is an early-mid 1970's Ford that has a later intake manifold installed onto it (a lot happens to these engines over the decades). And technically, we still don't know if it's a 429 or a 460, but the odds have increased slightly in regards to the possibility of being a 429.

The most certain way to tell for sure which engine you have is to look at the crankshaft after unbuttoning the pan and reading the crank's casting number, which is located on the leading or trailing EDGE of the third counterweight from the crank snout.

4U, 4UA, or 4UAB = 429 crank.

2y, 2YA, 2YAB, 2YABC (or 3Y) = 460 crankshaft

DOVE c heads
headman full leangth headers
Edelbrock performer rpm intake
Edelbrock performer RPM cam & lifters
True-Roller timing chain set

havent decided on a HEI Distributor or not

open for suggestions,and comments,

thanks guys

The engine could have come from a Lincoln, a Ford, or a Mercury, regardless of the casting number indicatiing Lincoln in the decode books.

Start with your timing at 30* BTDC @ 3000 rpm and jet to spec, them investigate timing advances...shouldn't have to go over 34* BTDC @ 3000 rpm, and ususally 32* makes for a plenty happy motor in fair tune.

well thats fords system.... your date codes might not match but your engine is still matching numbers... i personally love it... it makes it a lot easier to make a legitamate matching numbers build

well this engine is in a 1965 f-100, and im not so concerned about matching numbers, im wanting performance

If it's a 71 Lincoln, it's a 460 unless the crank has been changed.
Timing calls for 10B
later, Ron

is there a formula to determine what engine compression is by checking compression at the spark plugs ?, i did a compression test mine is reading 90lbs, i took 1 spark plug out at a time and turned it over 3-4 times,

Year is easy.....assuming a stock/not messed with engine....pull any rod or main bearing half. They all have the date on the back of them.
